Lobster Design

[Satan]

Hi, i would like to design a powerboat in american style.
I'm oriented around a modern lobster boat that are fashionable in this time.
My ideal lobster-boat have that configuration.

Loa 15 m
Beam 4,60
Displacement 20 tons

I want to study the perfect planing hull forms for this type of boat,build one or more models in scale.
What do you think about these images?
I'm in the right direction?



My research area is pointed about spray rails and lifting strakes for this hull.
I know that everyone have a personal method and that aren't a right rule to follow for find a perfect position of Srails and Lstrakes
Only solution is to make a CFD analysis but anyone can help me to find a document around this study?
Thanks a lot

o.k. Satan,,,,dont put lobstermen down like that,,,hehe,,we call it a "downeaster (pronounced "dawn easta" and i think theres a " ' " in there somewhere hehe ) i built many of em,, but i "put things" where THEY told me to,,, sorry,,, but some of the models that "millionaires" go after you could look at,,,,Hinckley,,Morris,,Jonathen Williams,,and MANY more,,look at boat builders around maine ,,they build ALOT of the "types" boats your looking for

The sheer is all wrong for this style of craft as is the hull form. The boat you're looking to mimic is well documented and round bilged not hard chine. Most of these where semi displacement shapes, not full plane.



The style you're looking for (26' hull)



The lobster boat races in Friendship a few years back.

If you wanted a hull like the so called American "lobster boat", your drawing is all wrong for that type. You have drawn a full planing hull with a hint of hook to the keel buttocks. Not at all like the semi-displacement and round bilged lobster boat with maybe a bit of rocker to the buttocks lines.

I didn't want to offend lobstermen with my idea.
I have mistaken to call it lobster , the only lobster's detail are the arrangement of the deck and the pilot house.
I'm inspired by toymarine and mochicraft boats to forge a new concept of
''false lobster yacht''.
The lobster are similar then Sicilian Fishingboat and i love it because remember the classic style of my land
