You'll find that strakes lined out by duplicating the sheerline will look
clumsy. Lining out the strakes thinner fore and aft will make a much better
looking boat. It doesn't take much to make a big idfference in appearance.
The strakes should be "more thinner" :-) fore than aft. As a start, take
3/16" (5mm) or so off the aft end of each strake and 3/8" (10mm) off the
front. Of course, you can cut each of those in half and then add about 8mm to
the center also.
BTW, the center isn't really the mid point of the profile, but is probably
about 65% from the bow. Dang, there's so much "eye" to boats, and a 2D
drawing doesn't show the actual effect. If you do the above by rote, you'll
be mighty close and it will look a bunch better than the "mechanical process".

Rich,
Trial and fit, not trial and error. ;-) Seal the wood extra good, and
rivet the overlap and you should be OK. Also if your going to lap strake
the sides you can use thinner wood.

Hi All,
I have been messing about with a set of old skiff plans from the
40's. On the original plans there are two planks for each side and
they are smooth joined, no overlap. What I have been trying to do is
to make each side have 4 planks and to have them overlap. I like the
looks.
In AutoCad, I just offset from the sheer line in equal amounts and
then added 1 inch upwards on each of the lower three planks (so they
would be overlapped by each upper lap). I draw in 2D so I don't think
the representation is right.
What I am wondering is, if because I am overlapping, do I have to
compensate and add more to each planks length? If this is the case is
there any fromula for doing this or should I just trial and error
this puppy?
Thanks for any help and have a Great Holiday Season.
When stressed, build a boat!
