Hull Curve

I notice there is a curve on the hull of the Pahi and Tiki designs, can anyone tell me if this curve has been added to the classic designs. (Tehini). I have the study plans for the Tehini and it shows the bulkhead profile as having straight lines and no curve. I have emailed Wharram but can't get a response.

It's good to see I'm not the only one who drinks and posts.

The curved V-shape causes more leeway.

With Pahis JWD use daggerboards to compensate , with Tikis they use an additional keel.

So if I respect the architect and pinch a few ideas from the Tiki 46 i.e.: the slight camber and stubby keel am I OK.

The fact that JWD does not reply to your email says everything. Hull shape and connecting structure (beams and their attachment) are the most essential part in any multihull project. Change those and you get a different boat. Why choose a Tehini if you do not like the hull shape? Why not build a T46 if that is the hull shape you like? Why investing so much money and work if you do not even know what kind of boat and what sort of sailing characteristics you will get for that? Why investing in an untested design?
