Zirk Botha at 3/4 of Cape Town to Rio solo row, sponsored by juwi Renewable Energies

Extreme South African adventurer, Zirk Botha (59) has passed the three-quarter mark in his transatlantic ocean row from Cape Town to Rio de Janeiro, a total distance of 7200km or 4000 nautical miles (nm).

He is the first person to attempt the journey, rowing alone and unsupported by any safety craft, and his pace is setting records that will be hard to beat.

‘I am making good progress and getting closer to the Brazilian coast. I’ve completed 3000nm in less than 8 weeks, this equates to a daily average of 58nm, with an average speed of 2,48kn. The weather forecast is in line with my weather routing prediction, the plan is working. I still have another 1000 nautical miles, or 1850 km to go, so I won’t be slowing the pace,’ said Botha. Zirk has remained healthy and strong, except for a slight strain to his right knee, but this is recovering well. Zirk comments: ‘I found that by raising the seat slightly, using extra foam padding and not rowing to my full leg extension, the pain has gone away and I am back to normal.’ As Zirk reaches the Brazilian coastline he will have to navigate around Trindade Island, fishing areas and oil fields: ‘I want to stay well North of Trindade Island and the fishing banks. The sea conditions will get worse over the shallows and there might be fishing vessels. I intend to pass inshore of the banks, have the NE from astern and to pass just inshore of the Southerly oil fields.’

Zirk has been out at sea alone and unsupported, aside from a few passing ships in the distance and only occasional sightings of marine life: ‘Early on my voyage I spotted a large sunfish. Near halfway, I saw the two dolphin pods and two marlin – I spotted a small marlin, about 1,5m, but it was very skittish and swam off very quickly. The big marlin I saw was stunning. It passed very close to the boat, but didn’t stick around. My highlight was the one pod of dolphins that played around Ratel for about 10 minutes.’

Sponsored by juwi Renewable Energies, Zirk is rowing in support of sustainable development and to promote renewable energy as a solution to environmental issues and climate change. ‘I want to use #Row2Rio2020 to spotlight the impact of fossil fuels and irresponsible consumerism on the planet, which will be the home of our children and future generations. Renewable energies are essential to a sustainable future.’ ‘During my entire row I have to be 100% self-sustaining. This provides a perfect showcase to support the message that 100% renewable energy is the solution. I am totally reliant on solar panels and solar-charged batteries as the source of electricity for my water maker (desalinator), auto-pilot, safety equipment, radio and satellite communications equipment.’ Richard Doyle, CEO of juwi Renewable Energies, sponsors of the trip, applauds Botha: ‘What Zirk is doing is remarkable from an individual perspective. However, it is really symbolic because it is a proxy for the greater effort we all need to make both individually and collectively if we are to realise sustainability.’ ‘Renewable energy made up 28% of the global total last year, up 2% on the previous year. There is a steady shift investment appetite away from fossil fuels and this percentage will only increase.’

‘juwi’s vision is 100% renewable energy and it is increasingly clear that many businesses can get there with energy management and storage. Zirk is a mini-example of this with the sun providing all of the navigation, communications and other electronic functions for his trip,’ adds Doyle.

What makes Row2Rio2020 different?

The trip is the first solo, unsupported, attempt to row the 7200km route from Cape Town to Rio de Janeiro. (A route very similar to that of the Cape to Rio Yacht Race). Zirk Botha initially had no big sponsorship to buy a fully equipped ocean rowing boat, so he had to teach himself how to do epoxy work and built the boat in his garden: ‘I fitted all equipment myself and did all the electrical wiring. Also something I had to teach myself to do,’ said Botha. No other solo rower has done this transatlantic row that includes coping with the Cape of Storms: ‘As a solo rower I am on my own and have to deal with all physical, mental and emotional challenges by myself – no shoulder to cry on. I have to navigate myself and there is no one to keep a visual lookout for ships or changes in weather conditions while I am sleeping, so my sleeping time is impaired.’

‘When I am not rowing I have to make water, clean the hull and do general maintenance, laundry, impacting on the time I have available to rest or sleep.’

‘I have always been inspired by the South Africa solo adventurers like Mike Horn and Pete van Kets. Being solo adventurers has set them apart in their ability to face and deal with challenges in often hostile environments without any outside assistance, and in this regard Mike Horn stands head and shoulders above the rest globally,’ said Botha.

About the boat

The current norm is for ocean rowing boats to be built from marine plywood or in a fibreglass and epoxy mould. Ratel differs from this in that she is built on a design by Phil Morrison using closed cell foam laid up with fibreglass and epoxy resin.

The specific design incorporates honey comb construction principles which ultimately makes it very strong when considering it is super light.

‘Before I started fitting hatches and equipment I could lift and turn Ratel by myself with one end on the cradle. With all equipment, spares and food loaded, she weighs maximum 550kgs. With a length of 6.5m and beam of 1.62m she is super light,’ said Botha.

‘To operate my systems I have 2 x 12V batteries connected in parallel with a combined 200aH capacity. These are deep cycle batteries suited for charging with solar panels.

‘I chose Solbian flexible solar panels because of their good track record on yachts and boats. With a peak capacity of 276 watts at 46 volts, they deliver maximum half of that owing to be positioned at various angles to cater for morning, midday and afternoon sun. They have consistently delivered even on overcast days and as such my batteries have been fully charged every day at sunset.’

Fitted onboard Ratel is a desalinator that provides my fresh water. The Eco Systems Splash unit can make 16l of fresh water per hour. It runs off 12 volts and requires a 16amp supply.

‘Besides the desalinator my most important unit is my VHF radio equipped with a GPS, AIS and DSC facility. The AIS allows me to get early warning of ships in my vicinity whilst the DSC allows me to communicate with them similar to as by SMS. I am also able to call ships on normal maritime channels.’
