I think my Taipan hull is 0.34 mtr wide at the widest point; shall we start at 0.35 mtr.

Again the hulls volume must at lead be 500 liters or it will sit to deep in the water. I think 550 liters is the total volume of the Taipan hull and that one is a bit to deep in the water when sailed by crews heavier then 145 kg. So lets start for our project with a total hull volume of at least 600 kg. That would be a good start also.

Can you tell that I've done this before ? <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

Ohh, lets decide to ONLY use SI units like mtr. kg, liter, newtons and no US or imperial units. Till save alot of work and miscalculations.

For example under SI the displacement of a volume is simply the product of the volume in mtr^3 times 1000.
