Converting a displacement hull for planning?

Thanks to your help and opinions I will modify my hull next year.
my conclusions are:
- weight , power , hullform are important
- the modification with a sufficient plate can be done at small budget.
- a testrun will hopefully show at least a semi displacement increase of speed
with 17hp
- More wishes are a question of more power at the given weight - to be decided
during next year.

 

Tom:
A lot of Shad boats were modified that way. Some Bay boats too, because they squated too much. I am sure they are disappearing with time.

 

Somehow this has escaped my notice and I will look into it the next time I'm at the Maritime Museum. I have sailed a traditional shad boat and it is abominably slow.
