From what I can determine, once a boat is on plane, it is primarily
the weight that determines fuel efficiency so a lighter weight boat
should give much better fuel economy.
BUT, as I have found with my Tolman which is very light for her size,
a lightweight boat is easily pushed around by a wave due to less
momentum. So, although you might consider a boat made from new
lightweight composites, would it be as seaworthy as a heavier one?
This is actually a practical consideration for me if I build a Tolman
Jumbo with slightly gretaer deadrise than the design. More deadrise
will make her pound less but will the lightweight make her less
seaworthy than similar heavier boats?

At one time I thought HK new something about boat design but he gives
me no reason to think he does.

He has stuck his foot in his mouth enough times to prove he knows
nothing about design or building. Most of the time he doesn't even
know he is saying something that makes that point so clear.. He don't
know, what he don't know.. makes for funny **** sometimes...

I've seen photos of your rowboats. You're a funny guy. Most of what
you've "built" is barely suitable for a voyage across a swimming pool.
And those stained seams!

Any idiot can build a dingy dinghy. You're proof of that.

Because I laugh at your "ideas"? Well...it's hard to take you and your
boating ideas seriously, froggy.

Power required for a given speed is directly proportional to weight,
for both displacement and planing vessels. Power required varies with
the cube of speed. Mileage varies with the square of speed.
