This is my boat, a so called "Backdecker or rather a "Vorderkajütkreuzer" designed by Robert Franz in 1927. It still has the original 1927 13-HP petrol engine from Breuer, which still works very well, as you can see.

I hae a few questions , wether she would go faster with a bigger engine, but before discussing this issue, which possibly has something to do with the underwater lines of OhekaII, I will take her out of the water and post you a foto of her underwater lines.
