Is pitch something like bow rise?

Yeah, that's what I am trying to figure... I have a program that will
show me waterlines and some simulations but I need to know about how
much bow rise I might have...

Most designs like that tend to ride fairly flat at full planning speed
but it will depend a lot on speed and loading.


Thanks... as I looked at google today I am starting to get that idea...
I did increase the deadrise to 13 degrees today but gave the bow a bit
more lift too and if I go ahead and make a slightly forward mount to
keep the prop under the hull, it should stay even flatter... thanks
Wayne, I was hoping you would pipe in here, assuming you see a lot of
boats in that size range...


You seem to be discussing two different things. The term "bow lift" is
usually used to define how high the bow rises when the boat is at a
particular speed, with the max rise just before it comes up on a plane.

The way you are using "bow lift" in your question appears to be related
to the pitch of the hull in the basic design of the boat.

That's what it sounds like to me anyway.

When I say bow lift I am refering to exaggerated lifting strakes near
the bow to keep the bow higher in rough water... (hopefully)...



You're going to end up with an underpowered boat that if it does get up
on plane, pounds on small waves. Even a much heavier 20' fiberglass
center console boat with 18 to 20 degrees of deadrise at the stern and a
really sharp entry at the bow is likely to pound in rough water in Long
Island Sound at decent planing speeds. I'm assuming by "rough water,"
you mean a patch of one foot waves on a lake or river.
