Craft Design 2.3 or is it 10.2? (But this is THE ONE!)

Procrastination

It literally feels like yesterday when Smile FM Radio announced live on 13 May 2019 that I was going to kayak solo and unassisted across the Atlantic Ocean. Much has happened since then, but this story is to pick up on the latest update around the actual design of the OCEAN X KAYAK.

Fast forward to post-Covid and the 13 August 2020 …

Almost to the day, eight weeks ago, I was having coffee at my local shopping centre with a well-known yachtsman, Nick Leggett, and while I was trying to convince him to join the team and offer his weather routing skills, a friend, Shaun Ferry, popped over to say hello.

Shaun asked for the latest news on the kayak design and build. I told him that I was still looking for the best boat builder to fit my needs and that I had been in contact with several possible options but had nothing concrete. He casually asked if I had chatted to Richard “Thirsty” Bertie?

Keep in mind that I am a terrible procrastinator, of the worst kind!

“No, not yet. But I was going to,” I replied.

Shaun is not a procrastinator. He just took out his phone and called Thirsty then and there. After a quick chat. he passed the phone over to me and said: “Here you go, speak to him.”

That was the start of what I needed to get Ocean X back on track.

Later that day was the first time since July, when my friend, kayak builder and designer Uwe passed away, that I was able to get access to his laptop to see if I could find a copy of the design drawings. Unfortunately, all that I could find was a single CAD file. Most of the latest design discussions and modifications never made it to this file. Check out my blog post from June here.

A week later I met with Richard in Noordhoek to seek his assistance in the construction of my kayak. I think it took him a few long minutes to digest what I was planning and whether I was a complete nut job, or if there was something more to it.

I am very pleased to say he became quite intrigued by the whole idea and by the time we had said our farewells he had contacted someone to do the build. He also contacted a good friend of his, a yacht designer by the name of Phil Southwell, and convinced him to spare a few hours to complete the design that Uwe had started.

I remember driving home over Ou Kaapse Weg and thinking how amazing that short meeting was. The kindness, honesty, enthusiasm, and knowledge that Thirsty was going to bring to the team gave me the huge boost that I so badly needed.

The Designer

Phil Southwell sailed into Cape Town in 1981 and has been in South Africa on and off ever since. He designed with Lavranos & Associates for almost seven years, gaining the required experience after completing his degree for membership of the Royal Institute of Naval Architects. Phil Southwell established Southwell Yacht Design in 1989 and he designs exclusively in 3D.

I finally met Phil the following week. I had sent him a few screen shots of the CAD drawings beforehand and must admit that I felt a little out of my comfort zone. Uwe was a good friend and we talked openly and debated each concept of the design until we were both happy with each item.

I had never met Phil before. I knew of his reputation as a top-class designer. What I did not know was to what extent he was willing to assist. I should not have been concerned. Phil has put in countless hours into the design and is a remarkable talented designer.

In the past five weeks we have taken the original drawings and have gone through another 10 versions/design changes! We have a design/build team meeting weekly and when I listen to Phil, Thirsty and Dylan discuss how each aspect of the design fits into the reality of the construction, I sit back and smile quietly to myself knowing I have the best of the best on my side here. Well, it’s actually because I have no idea what they are talking about! ?

Phil, Richard, Dylan discussing craft design

ABOVE: Phil, Richard, Dylan discussing stuff I don’t understand.

The design

The basic dimensions of the Ocean X kayak are 8m long and 94cm at my paddle entry. The rudder is transom hung and will knock up if it collides with anything. I prefer the transom rudder to having a rudder shaft running through the hull from a safety aspect and accessibility should anything need attention.

For increased stability and weight reduction I have opted for a short lifting keel with a lead bulb (30-50kg) versus using water ballast in the hull. There is a compromise between using the weight of water ballast versus the drag of the keel. I feel confident that my design is on the correct side of this equation.

The keel box has been designed to absorb a collision with an object or beast. It has compression/absorption zones fore and aft as well as shear pins. If the keel was to fall off, then I have the backup of using water ballast bladders for extra stability.

In the front of the hull there is a lifting canard (skeg). This will be pulled down only when there is wind from the side. The windage on the cabin, which is in the front, will cause the bow of the kayak to blow away from the wind. The canard will help counter this action.

The kayak is of a carbon core construction and should weigh in at around 85kg without the lead bulb of the keel. The maximum overall weight of the kayak, gear, food and I can be no more than 400kg. Obviously less is better but to take enough equipment and supplies to keep me alive for up to 80 days does not come without its weight challenges.

See below for a snapshot of the design progression starting with my own crude drawings to Uwe’s and finally with Phil’s perfection that goes into manufacturing today.

jetboil

Jet Boil Review: Cooking at sea

All my cooking will be done with boiling water. I will have no need to fry, bake or the likes.

Jetboil stoves are brilliant. The Jetboil is far and away the best system I’ve used. Fast, compact and efficient. I will take a number of spare lighters, because the ignition unit is a major weak point in a salty environment.

The Jetboil only uses 5g of gas to boil 500ml of water. Allowing for some waste I should only need to take as little as 2.5kg of gas. As with every system on board I will have a backup plan. My alternative cooker is due to arrive on Tuesday so I will do a review of it after I have thoroughly tested it.

I will make my freeze-dried meal in a thermos mug and not in the bag that it comes in. If I make it in the bag, I have smelly rubbish to keep someplace (all plastics will be audited before and after).  The thermos mug is washable, and also means I can allow the meal longer to rehydrate fully without it going cold.

I will need to make a gimbal system for the cooker so if there are any engineers who have some time on their hand and would like to do this for me it would be much appreciated.

Jetboil Review at Sea:

 

 

hands of an ocean paddler

Grampa hands, gunwale bum and slow roasting

My body and mind are going to be pushed to the extreme during crossing my from Cape Town to Salvador in Brazil, and one aspect that people don’t realise is the constant exposure that my skin has to deal with.

Skin problems like buttock irritation, hand scaling and sunburn are the most common issues that ocean-faring adventurers suffer from. You can see from the graph below after a 24-day transatlantic yacht race what skin ailments the competitors developed. Keep in mind these sailors can stand and walk around.

I can’t!

skin lesions

 

Grampa hands

Scaling is peeling or flaking skin and it’s an unavoidable issue when your hands and feet are wet for extended periods. Paddlers’ hands tend to lose their natural oils from being soaking wet and with the constant squeezing action of gripping the paddle shaft on each stroke. After a while, the skin can form friction blisters as the oils in the skin no longer act as a lubricant between the layers.

The trick to try to limit the loss of natural oils is to pre-oil my hands. Typically, I apply the likes of petroleum jelly or “Dubbin” – a leather oil that was the only way to waterproof those old leather rugby balls – before a paddling race that gets absorbed into the skin. You must allow time for it to soak into the skin or the paddle will behave like a slippery eel in your hands.

(Pic above) The hands of an ocean rower.

I will also use gloves to reduce the build-up of blisters but the drawback of gloves is that my hands remain wet when the gloves get wet, so it’s a careful management of the tools to limit hand-scaling and blistering.

Gunwale Bum

The dreaded “gunwale bum” is the one I am most concerned about – for obvious reasons! There are many names for this skin ailment, but the medical term is Folliculitis, which affects the hair follicles of the skin.

 

gunwale bum

(Pic above) Mild folliculitis (TMI??)

Folliculitis occurs when hair follicles become clogged and infected with bacteria, leading to red bumps and pus-filled follicles. These bacteria usually live on the skin without incident but under the strain of constantly sitting (friction) in salty damp (sweaty) conditions, the bacteria get clogged and irritate the hair follicles – causing bumps that look like pimples. It can range from mildly irritating to completely debilitating, but if left unchecked they can turn into abscess or boils. Should this occur it would be very difficult to sit, let alone paddle!

So how do I combat or limit this painful issue? My first defence is regular washing to keep the follicles clean by removing dirt, oil, and sweat. The problem here is that water is a very scarce resource. I have considered using baby wipes, but they are not ideal as they can be a little harsh on the skin and keeping used baby wipes around for 80 days is not very appealing!

Another method is a barrier cream with an anti-fungal component. As a keen cyclist I use this type of cream on the chamois of my shorts. So, could these creams work for paddling? I won’t have chamois in my paddling shorts and I won’t be wearing shorts (eek!) most of the time, so I would apply directly to my skin.

I have been doing some testing for some time now and these are the products on my test sheet.

barrier creams

(Pic above) Sudocrem, Ass Magic, Madaji Milking cream, Squirt Barrier Balm, Dubbin

The testing ensures I don’t have any negative reaction to the cream, and I can evaluate how they hold up to the wetter conditions of kayaking and how easy they are to wash off.

Sudocrem, Ass Magic, Madaji Milking cream, Squirt Barrier Balm, Dubbin

(Pic above) Sudocrem, Ass Magic, Madaji Milking cream, Squirt Barrier Balm, Dubbin

I have placed them in order of their viscosity. The thickest on the right being Dubbin, which will be only used on my hands.

  • Sudocrem : Nappy rash cream.  Antibacterial/fungal = Zinc Oxide
  • Ass Magic : Chamois cream. Antibacterial/fungal = Zinc Oxide and Tea Tree Oil
  • Madaji Milking cream: Udder cream for cows (also marketed for humans),
  • Antiseptic = Chlorhexidine
  • Squirt Barrier Balm: Chamois cream, Antibacterial = Tea Tree Oil

A big “thank you” to the team from Squirt Cycling Products who arranged a bunch of goodies from their product range for me to test. It’s inspiring and really lekker to have support from local Proudly South African companies. Testing will continue over the next few months before I settle on my favourite.

Sun Protection

My final skincare thought process goes to sun protection. The kayak stroke does not lend itself to an awning for sun protection. While paddling during the day I will be under the powerful rays of the sun. There is literally no place to hide from its relentless force, and not only from directly above but also from its harmful reflection off the water.

The first bit of the crossing, while it’s cooler, I will wear a long sleeve top – like a rash vest. But as I get more into the tropics, where the water is 28 degrees Celsius and the outside temperature – sitting in the sun – gets well into the 30s, a rash vest too will get unbearably hot.

Sunscreen will be my final defence. I favour a spray-on light cream with an SP factor 50 that is also waterproof. I will have to apply the sunscreen multiple times a day, as sweat and water eventually reduces its effectiveness.

For face protection I always wear a wide-brimmed hat, and better yet, I hope to get something like this hat (see pic below) that will shield the relentless and uncompromising glare of the sun from the water off my face.

Safety at sea

Navigating my way across the Atlantic Ocean from Cape Town to Salvador in Brazil is no mean feat, and in order to achieve my heady task I will need a few gadgets and safety essentials to ensure my Ocean X journey goes according to plan.

Here is some of the safety items I will need to paddle on this mammoth adventure:

Life Raft

First and foremost, this is a lifesaving essential that I hope to get my hands on soon. It’s a Switlik Inflatable Single Person Life Raft (ISPLR) and they are mostly used in the aviation industry. It’s compact and lightweight (2.8kg) – the only option for a craft as small as mine. But they come with a hefty price tag, so if anyone has one that they are not using for a few months I would be most appreciative.

EPIRB & PLB

There will be an EPIRB (emergency position-indicating radio beacon) and a 2 x PLB (personal locating beacon). Both work in similar ways but the EPIRB will transmit for a longer time (48hrs) due to its battery size.

An EPIRB is a safety device to alert search and rescue services, allowing them to quickly locate you in the event of an emergency. When activated it transmits a coded message (GPS position – Boats or Persons details etc) on the 406 MHz distress frequency, which is monitored by the COSPAS-SARSAT satellite system. The alert is then relayed via an earth station to the nearest Rescue Coordination Centre. The satellites are in a polar orbit, so they offer true global coverage.

Epirb

ABOVE: How an EPIRB works

A PLB is a specific type of EPIRB that is typically smaller, has a shorter battery life, and unlike a proper EPIRB is registered to a person rather than a vessel. With a PLB you can summon help wherever you are on the planet, no matter how remote.

Epirb and PLB

ABOVE: Example of an EPIRB & PLB

 

Satellite Telecommunications

I will have an Inmarsat Satellite phone that will enable voice calls depending on the need like radio interviews, advice on repairing a piece of equipment or emergency services.

Inmarsat Coverage map

The Iridium Go allows me to make voice calls and text messaging via a smartphone. It also has other capabilities like a basic email service and will be used to receive my weather updates. It is one of the three tracking units on board.

GPS Tracker

There will be another two dedicated GPS trackers on board that will transmit my position, direction and speed to my shore team at defined intervals. These intervals are set depending on the likes of power consumption. My track will be automatically uploaded to my webpage for everyone to follow in real time.

AIS

The Automatic Identification System (AIS) is a digital VHF radio-based transponder system that can prevent collisions, and more importantly, protect me from being run down by a huge, fast-moving ship!

Picture a radar-chart plotter display, with overlaid electronic chart data, that includes an icon for every significant ship within VHF radio range, each showing that vessel’s speed and heading. Each ship icon reflects the actual size of the ship, with positions accurate to GPS precision. By “clicking” on a ship mark, I can learn the ship’s name, course and speed, classification, call sign, MMSI, and other information.

The system’s range is like that of your VHF radio, essentially depending on the height of the antenna. AIS information is not degraded by rain-clutter like radar, so it works the same in all weather. AIS is extremely valuable, especially at night or at times when there is restricted visibility.

Body Leash

When outside I will always be attached to the kayak by a 10 ft body leash. I will use either a waist or leg leash depending on what I am doing.

leg leashWaist leash

ABOVE:  Leg Leash (left), Waist Leash (right)

Life jacket

I will have an inflatable life jacket seen in the image below. My second PLB will be permanently attached to the jacket.

life jacket

Flares

I will carry various signal flares in the form of a hand-held, rocket and smoke flare. Each type of flare is used for a specific purpose. Their purpose is to attract attention when immediate danger exists. They are only useful if someone is close enough to see them, so I need to use my good judgement when using as they are single use.

See the diagram below to understand each types range

flare range

handheld flareflares

Fire Extinguisher

One small unit will be on board. Always a standard precaution!

fire extinguisher

Medical Kit

A comprehensive medical kit will be put together to cover all possible scenarios, which I find are always needed at any time.

VHF Radio

There will be two VHF radios on board, the main and most important one will be a fixed unit inside and the other a handheld unit. The fixed one has a greater transmitting power (25W) and thus a longer range than the handheld (5W).

VHF RadioVHF radio

Radar Reflector

The kayak will give a very poor echo on a ship’s radar, especially in rough seas as it is so small and made of fibreglass. A tube radar reflector is simply an arrangement of metal elements crossed at several 90-degree angles in a plastic casing to reflect energy from the radars and thus enhancing the signal of the vessel.

I am being optimistic, I hopefully won’t need to use half of the above…but always be safe rather than sorry, the ocean can be a dangerous place.

solar panels on my kayak

Solar Power = Water = Life

My unique ocean-crossing kayak needs an electrical source to power its numerous electronics required for me to achieve this heady task awaiting me. The biggest consumer of electricity, which is the most important aspect of my journey, is the water maker. Electricity can be generated using solar panels or wind generators.

In my case: Solar Power = Water = Life

Richard Kohler Kayak

As there are so few kayak crossings, my research focused on ocean-rowing boats. I found that the majority of them experienced some sort of power problem during their crossings, so I need to ensure that I avoid similar issues.

The power generation and storage system for crossing has been designed by Tiaan Oosthuizen, a Tshwane University of Technology Solar Team Member & PhD student. Tiaan has studied the average sunshine for the past 22 years over the entire route I will be paddling. He has based the power generation requirements with this data against the power consumption expected by the electronics on board. Isn’t science and technology just great?

The daily average sun yield will decrease by almost half the closer I paddle to Brazil. When I leave Cape Town’s shores, there should be about 3kWh/day reducing to 1,8kWh/day near Salvador. The solar system I will be using is meticulously designed with a worst-case scenario in mind. Safety first!

Solar Panels

Solar Panels are often used for electrical generation in rowing boats, and reliably produce energy for its systems. However, in foggy, overcast, or rainy conditions their output is significantly reduced. Considering the nature of this kayak and the limited space available, flexible solar panels are best suited for my daily requirements.

Performance is in direct ratio to cost, and unfortunately they are not cheap. A unique design departure that will dramatically increase solar power output are the two lifting and tilting side panels on the front compartment. Total solar array is 380watts.

Wind Generators

Cost for cost they can produce more energy than solar panels. But of course they rely on steady winds and should be mounted as high as possible to get the least interrupted wind.

On a small kayak the main concerns are the weight and resistance of a wind generator and the negative effect this has on the stability of the boat. Considering that the average winds are expected to reach 12 to 15 knots, less my kayak speed, will give me an average of say 10 knots (5.2m/s) of wind. Looking at the graph below it is evident that there is not enough wind speed for efficient use of a wind generator.

graph of air power curve

Solar Controller/Charger

A maximum power point tracker (MMPT) is an electronic DC to DC converter that optimises the match between the solar array (PV panels) and the battery. To put it simply, they convert a higher voltage DC output from solar panels down to the lower voltage needed to charge batteries. MPPT controllers are 93-97% efficient. The charging information will be available to me via a Bluetooth app.

Batteries

It is necessary to store the energy from the solar panels or wind generators and this will be done using two 12V 100ah LiFePO4 batteries. Traditionally marine deep cycle lead acid batteries have been used, but they only allow a maximum of 50% discharge and ideally as little as 20%. This would require at least twice the battery capacity compared to lithium-ion phosphate (LiFePO4). LiFePO4 batteries can be discharged to a much lower state of charge without damage. However they do come with a hefty cost penalty.

BMS (Battery Management System)

The two 12V 100ah LiFePO4 batteries come with a built-in BMS. It is the brains behind battery packs. They manage the output, charging and discharging, while also providing notifications on the status of the battery pack. They also provide critical safeguards to protect the batteries from damage.

Controlling the over and under voltage, overcurrent and short-circuit protection, over temperature and cell imbalance, the BMS monitors the battery to ensure safety and maximum lifetime over the full range of operating conditions. Most importantly, everything I need to ensure I remain hydrated! Water = Life.

Below is an overview of the power system

Southern Atlantic routing chart for Januay

Weather, winds and route to Brazil

The mammoth challenge that awaits me as I mentally prepare for my Ocean X odyssey offers a rather simple, yet complex question: when is the best weather and correct time to kayak across the Southern Atlantic?

It would be virtually impossible to kayak across an ocean if the elements are not in your favour and the most important weather elements to consider are the winds and currents. Failing to prepare leaves me with no option but to prepare to fail and even that theory can be quashed by the sudden change in the elements of Mother Nature.

The Southern Atlantic Ocean is dominated by the South Atlantic subtropical high pressure, which basically sits over the middle of the ocean. In the centre of the high pressure there are generally calm winds and variable winds. Moving outwards the wind speed and direction become greater and from a more constant direction

I’ll be departing from Cape Town and those who live and grew up in the fairest Cape know that during the winter months the cold fronts (low pressure systems) bring the north-westerly winds that create big sea swells and lots of rain.

The direction that I will be heading on my journey from Cape Town to Brazil is in a North-Westerly direction so trying to paddle into a headwind during the winter months would be futile. I’d be wasting a lot of time and energy for hardly any gain.

South Easterly Winds

During the summer months though, the opposite happens as the South Atlantic high moves South and pushes the cold fronts downwards and away from Cape Town. Summers here in the Cape are normally dominated by the South Easterly winds that blow in the direction that I want to pursue in achieving my Ocean X dream.

A week after leaving Cape Town it is highly likely that I will move into an area of consistent South Easterly winds known as the Trade Winds. These winds blow in an arc around the high-pressure system, thus helping me towards Brazil.

trade winds

The ocean winds are also the main driving force of the ocean currents and they generally follow the direction of the winds, so waiting for the summer months will again work in my favour. ‘Timing is everything’ as they say in life.

One thing about ocean currents is that they do not move in a perfectly straight line. There are lots of what is termed as ‘eddies’, which is a circular current of water. It will be very important for me to not get stuck in the bogey counter-currents known as ‘eddies’.

When sailors – and now kayakers – plan for an ocean crossing, they use what is known as routing charts. There are routing charts for every month of the year, which indicates the average conditions that could be expected for a given month using empirical recorded data over the past 20 years.

Southern Atlantic routing chart for January

Southern Atlantic routing chart for Januay

On the right-hand side of this chart there are detailed overviews of the temperature, wind, visibility and the wave heights.

Wind description

As you can read from the image above of the wind description, the South East wind is the most dominant between the Cape of Good Hope and the Horn of Brazil – a good time to be kayaking over 6000kms across the ocean!

A routing chart also includes several smaller inserted charts as seen in the image below.

gales and pressure

As you can deduct from the gales and pressure the red numbers in the centre of each square show the average percentage of ship reports in which winds of at least Force 8 have been recorded. The blue lines show the average barometric pressure at sea level.

This chart shows the mean air temperature in Celsius in the red line showing every 2 degrees. The blue lines show the percentage of observations reporting visibility of less than 2 miles and the green lines are the average sea surface temperature in Celsius and show for every 4 degrees.

Wind Rose

wind rose explanation

Every 5 degree square on the routing chart includes a Wind Rose. Above is the explanation of the Wind Rose. A cursory glance of the Wind Roses between Cape Town and Brazil show the South East arrow is the most dominant, which compares with the general wind description as indicated earlier.

But if you take a closer look at the Wind Roses around Cape Town you will notice there is a fair amount of wind blowing from other directions.

The most problematic wind for my departure would be the South West and Westerly winds, which could potentially blow me on to the shore wreaking havoc before I have even left the fairest Cape!

I will have to wait for a weather window that has about five or six days of Southerly and South East winds that will enable me to get North / a little bit West, so if I do encounter any winds from the West I would have made enough sea room to keep me from being blown on to the shore.

The other thing to note are the thick red lines that indicate the percentage frequency of having wave heights greater than 12 foot.

This brings me back to the beginning where I posed question: when is the correct time to kayak across the Southern Atlantic?

It would be virtually impossible if the elements are not in your favour and the window period for me to achieve my ultimate goal is December to the end of February when I can look forward to catching that treasured glimpse of South American land.

Keep paddling!

Hand Surgery

Finally went for the upgrade of my left hand.?️

The hand surgery was a dupuytren contracture fasciectomy. Basically the tendon gradually gets pulled over time and the finger/s start to curl. It was still in an early stage for me but far enough that I could not put my palm down flat.

Most importantly the paddle shaft was starting to irritated it and with 80 days of non stop paddling coming at the end of the year it was best to sort it out soonest.

I was super impressed with the medical team. They even arranged the COVID-19 test results in under 10 hours.

I was most fascinated with the “arm block” which enabled me to watch some of the operation. It’s quite surreal watching your skin being cut and pulled back without any pain sensation.

Recovery is longer than I thought but time will tell.

Ocean X Craft Design

Ocean X is Richard Kohler’s odyssey and later this year he will set off from Cape Town in an eight-metre paddling torpedo across the Southern Atlantic Ocean to Salvador in Brazil, entirely unsupported whilst raising funds for his charity, Operation Smile.

The remarkable aspect of this journey into the unknown is the vessel that will carry Richard along the way in achieving his ultimate goal. An 8m paddling torpedo allows very little leeway to move around after 15 hours and 100km of paddling every day, and every single inch of space needs to be utilised for optimal performance and comfort.

Kayak design

“The design brief was to keep it as close to a traditional kayak but that it should include a sleeping area that can protect me from the uncompromising elements typical of being out at sea,” says Richard. “The kayak is 8.5m long and 90cm at its maximum width. Considering an average shoulder width is around 50cm, it does not leave much room on the inside for me and my gear.”

The cramped conditions are one of Richard’s biggest challenges. Avoiding leg cramp and debilitating salt sores are daily requirements to ensure he remains at optimal levels to complete his heady task. While his arms are sure to feel the burn after 15 hours and 100km a day, his legs will need regular stretches, and possibly some water-kicks from time to time.

“I can’t walk to get pressure off my butt, so if I get salt sores on my butt I will be in serious trouble,” he explains. “While the sleeping compartment does not have enough headroom to sit upright, therefore there is a clear ‘jet fighter canopy’ that can accommodate my head when sitting. It will also give me better views of the world outside.

kayak design Richard Kohler

Power and water supply

From the outside there is a large array of solar panels with the two forward side panels that can lift upwards to present better solar absorption of the sun. Research indicates that having enough electrical power to make water is one of the highest priorities. In Richard’s survival of this mammoth task that awaits him; water equals life.

The kayak is self-righting and has a knock-up rudder to minimise damage from hitting potential floating objects. It also has a short lifting keel for increased stability, and in the bow there is a retractable canard that will be extended when paddling in crosswinds to limit the bow being blown off course.

kayak design Richard Kohler self righting

Non-visible features include a number of floodable/pumpable watertight compartments that can be used to increase stability, and when the weight is in the forward sleeping area the stern compartment can be filled to counter the extra weight forward.

The custom-made 8m paddling torpedo is designed by Uwe Jaspersen that will see Richard voyaging into the unknown in a kayak with a total weight of 380kg that includes gear, food and himself. “Uwe is behind the design, with input from myself based upon my requirements. I wanted to make sure it was as close to a kayak and as far away from a rowing boat as possible,” Richard explains.

“The exact length is still to be determined based on sea trials – narrow overall width, and small cabin to rest in – or hide in if needs be. The cabin is basically a sleeping tube that I can crawl into, and there is only one place to sit upright.”

It remains a stiff challenge nonetheless, but Richard Kohler certainly has the drive and determination to succeed in his endeavours. Having being attacked by a shark during his trip along the entire coastline of South Africa, nothing will stop this brave man from dipping his toes into the cold Atlantic Ocean yet again and raising money for Operation Smile.

Back on the water – post Covid-19 lockdown

Months after it was declared illegal to enter the ocean I got my first taste of freedom having being locked down due to Covid-19. How I have missed the ocean and training for my upcoming adventure.

It was spectacular to have a welcoming party. I wonder if the dolphins missed me as much as I missed them. ?
