Regal has a hull design that basically touts a "variable" deadrise, based on
lift.
This was an interesting read:

It takes a lawyer to claim that a shape hull shape can violate a
patent.
Every time my head creates a "new invention" I look on the internet
and see a vastly improved version already patented.
Once in a while when I forget to look on the internet, I see one of my
"inventions" already on sale at the store.

I actually make my living by inventing things and as the saying goes,
"Theres thousands of good ideas and most of them are wrong" certainly
applies to what I do.
To enlighten some people, "Faster than light travel" is prohibited
mathematically because it results in violation of causality, ie.,
effects happen before the cause (yes, there may be exceptions). There
is nothing mathematically wrong with a variable hull.
I have spent hundreds of thousands of dollars on ideas that didn't
work but I don't admit the ideas are dead .........yet. Sometimes,
something actually does work and you lean back and
think..........."DAMN, that is cool", being surprised it works.
It is perfectly normal for people to say "That can't work otherwise it
would've been done". You simply do not listen to such and go find out
why it hasn't been done.

You know who you remind me of?
Thomas Edison. With boats.
Keep at it, and you'll get there.
Or have plenty of fun trying.
Ever been down to the museum in Fort Myers?
That could be yours.
Always keep saying I'll go there, but I end up fishing instead.

Edison was lucky to live in an age when a new "thing", electricity was
being developed and he took full advantage of it. Today, the
analogous "thing" is software about which I know nothing but there
sure seem to be some "Edisons" of software. Not knowing much about
power boats, I cannot afford to gamble the $10,000 or so on a patent
for boating stuff. My patents all relate to x-rays which I do
understand (specialization is so sad).

I'm surprised that no one has mentioned lobster boats given the
history of this newsgroup and its most prolific contributor. Classic
lobster boats have a fine entry forward which flattens out as you move
aft creating a shape which gets through the chop with minimal muss or
fuss but can still get on plane with reasonable power and economy.

Varying the deadrise underway certainly presents a number of
interesting challenges - possibly with some sort of inflatable
structure?

I believe that lobster boats were an inspiration for Tolman's designs
although Tolman may have reduced the deadrise more.
Yes, I did consider an inflatable structure, seems sorta failure prone
but a possibility.

Just looked at Bateau's 26' Lobsterboat which has a similar hull
design compared to the Tolman but the Tolman is more extreme.
Lobsterboat has deadrise of 13 at stern whereas my Tolman is 8 degrees
at transom.
