Design Formulas and Trimaran Help

[photojoe]

I'm an Amateur yacht designer and I'm trying to design a 35' trimaran. My greatest problem is that there isn't any books for formulas for design them.

While I'm here I'm looking for a mathematical formula that can take sail area and break it down in to luff, leech, and foot. I'm sort of getting sick of drawing and redrawing a rig. Also how does one figure out and draw a full roach main that most multihull have and batten spacing? I had read a great article on the Internet about them and lost it. Also is their a mathematical formula for calculating COE for sails?

How does one calculate the RM and righting arm of a trimaran and a catamaran? How does one do heeling calculations for both?

Also any rules of thumb for calculating COB for a multihull or balancing the hull with engine, water tanks, fuel tanks, etc?

[Edit] Also for a multihull with a bowsprit, how do you determine load and scanting?

Thanks,

Joe

I'm waiting on the books.

Any suggestions for finding the engineering figures for the various composite materials? Tensile strength, Tensile Modulus, Compressive Strength, Density?

How does Epoxy, Vinylester, and Polyester resin alter the composite?

Thanks Again,

Joe
