From what I can determine, once a boat is on plane, it is primarily

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.


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