Hey Eckhart, interesting pics!
Do you have any more detailed pics - have been toying with the idea of building my own canoe(rudderless)..

Robert,

thanks for your interest.
I have made severeal detailed drawings of this design.
The starting point is a 'Godzilla' hull that has the appropriate displacement and the desired dimensions.
Godzilla is a software developed by E. Lazauskas.
This ideal hull is then merged with the drawings that are shown here. For this Delftship/Freeship can be used.
The resulting hull is imported into Michlet, again software from E. Lazauskas. In Michlet you can then evaluate the resulting resistance at varying speeds.

All this remains semiqualitative because this OC 1 is not a flat water vessel, but made for the open ocean.

Many question can only be answered by trial and error. Seaworthiness, how much rocker etc..

This current design will be changed to include a sharp canoe stern. The reason is that the following sea needs - to a degree - to be able to flow around the stern when the speed of the wave is higher than the hull speed.

Russerless canoes are easier to design provided you design them to be paddled in flat water. Look a t Godzilla/Michlet on the internet.

Robert, you could also just design your little heart out with the very easy to use free Kayak Foundry software. I designed an OC6, Oc4 and Oc2 all in one night.

It also prints out full size profiles for you to mount on a strong back.

Robert, Rambo,

yes, there is more and easier to use software out there, as well as there is expensive professional software.

I read somewhere: " do not use expensive materials for a cheap vessel " as a basic rule for boat building.

I am trying to match what I want to do with my ski9ll in building it. Neither will be perfect. So there is no need to be perfect at the design end for me either.
