It's not the depth but the angle of the "V" is what you need, that will give you the depth. Try for around 17 degrees.

I wish that I could, I'm not too good with these computer things like the drawing part. A shallow "V" is usually around 11 degrees which is close to what you have in your drawing. How fancy do you want to get?
here's one that I helped a friend do a little work on, he's a CAD designer by trade:

Mini mental,

Stand by, I am currently compiling the data you requested........watch this post.....

OK Here is the sizes of the wild thing. Its slightly smaller than it should be....not much, mine is 30in by 9in, should be 32in by 10 1/2in.

Deep Vee monoplane - has a deadrise of 16 degrees or greater, measured at the widest beam measurement. Beam is the width, freeboard is the sides (chine to sheer) and deadrise is the very bottom (keel) up to under the freeboard (chine)...... shiver me timbers....

Hope this helps....

Sorry to those who are not into metric....

Its OK Ron, I have the technology....

BOY, was I wrong in my measurements.[sm=spinnyeyes.gif] I went down and checked the angles on several of my monos and found that they were 25-30 degrees, a lot more than the 11 that I said before.

Ron,
Did you measure the angle like Mcleod did on his drawing? That's the 11° for the mono and 17° for deep vee. Mini-the deadrise, which is like your "s", but measured vertically, varies to suit your taste.
Watch out for water spray entering the boat when it's in a turn, you might design the deck to overlap the sides from the bow to 2/3 aft, or all the way back. This will deflect the water away. Where is your center of gravity, low or high? Where does the boat balance along the keel? Try to make the boat balance at a point 28% of the length of the boat, measuring forward from the transon (stern).
A boat with a low-slung engine will be more stable in roll, but if it's really low, the boat will tend to pull out of a turn and go straight. With the engine mounted higher, the it will be easier for the boat to lay over when turning.
Cool stuff! Good luck!
Will

Okay dude, thanks. i plan on mounting my engine reasonably low, and i aint botherd about water spraying onto the deck, i have a special material to put on air scoops that stops water but allows air to get through
