Pontoon Boat Plans | Trans Ocean Pedalboat

Pontoon Boat Plans


Davey du Plessis is an author, inspirational speaker and an adventurer who pushes himself far beyond the limits of us more normal people. He has ridden around the perimeter of Africa on a bicycle. He was doing a source to sea solo navigation of the Amazon River when he was ambushed and shot, then had to get himself back to civilisation. He was tested close to his limits in that adventure and still has the bullet lodged in his heart.

Daveys planned next adventure is to pedal a boat around the world. He approached me to design the boat and had his uncle, Tertius du Plessis, build it for him. The boat is now mostly complete and will soon be ready for testing.
Looks like a hi-tec starfighter but really a low-tec pedal boat.
While I designed the boat, I didnt design the propulsion system, which consists of a leg that has a conventional pedal arrangement at the top, inside the boat, and a plastic 2-blade propeller under the hull. The slow-rotating propeller has soft blades to reduce the chances of damaging marine life.

The styling looks very sleek and possibly intended for high speeds but high speed is not the aim. It is designed for low drag both in the water and above. A human-powered boat needs to be easily driven, to maximise the distance that can be covered for each unit of energy that goes into propelling it. That means that it must offer little resistance to the water and the air. The underbody is shaped for low drag at low speeds and to be easily steered in downwind tradewind conditions. She has a shallow barn-door type rudder, transom-hung.

Davey is sure to find very bad weather many times on his voyaging, so his boat is also shaped for low resistance to breaking waves that strike it and it is shaped to roll back upright when (rather than if) it is capsized. Stability comes from the tankage and stowage compartments placed low down in the hull to lower the centre of gravity. The deck and cabin are shaped to float the boat high if inverted with the hatches and ports closed, to make it unstable upside-down. Davey will also be able to use his own weight inside the boat to help it roll back to upright if needed.

Construction is stitch-&-glue plywood, assembled over permanent bulkheads and partial bulkheads. The interior is divided into three compartments, separated by full bulkheads with companion hatches. Both ends are berth length, to accommodate one or two crew for a voyage.

This coming weekend sees the Cape Town International Boat Show and Daveys boat will be on display.

This boat is not yet on our website but you can see our other designs at http://dixdesign.com/ and http://dixdesign.com/mobile.

Boat Plans Pdf | Review of South Atlantic Capsize Book

Boat Plans Pdf


The first review of my book "South Atlantic Capsize - Lessons Taught by a Big Ocean Wave", has appeared. This review was written by Richard Crockett, editor of Sailing for Southern Africa magazine. I will leave the review to speak for itself.

Front cover of the book.
More Really Good Books
 
One of the perks of my job is that I do get to read some really good books. Two I have recently read got into that ‘must read’ category.


The first is entitled ‘South Atlantic Capsize’ – Lessons Taught by a Big Ocean Wave.
 
It is written by Dudley Dix and tells the story of ‘Black Cat’, the crew, the 2014 Cape to Rio Race and the storm that struck the fleet in the opening days of that race. It’s a personal account of what happened on the boat when it was capsized, what damage was done, what the men onboard did to safeguard vessel and crew, what they did to get themselves back to port – as well as what else was going on around them.


It’s rivetting reading as it is not just well written, but written by a man with a serious understanding of the sea, yacht design, yacht construction – and ultimately what happened to them out there.

I like the fact that it gives some history of the Cape to Rio Race, a pretty detailed account of the boat’s design and construction and his careful selection of crew. To many crew selection is simply a case of asking mates, but for Dix it’s far more than that.

So, for anyone contemplating competing in the 2017 Cape to Rio race, this book should be read, not for the scarey stuff, but for the practical preparation tips, and advice on handling bad weather. For those simply making passages at sea, there is lots to learn too.

Thank you Richard Crockett for the review.
