Speed formula

[dick_james]

Can someone remind me of the formula for determining the speed of a displacement hull. I wrote it down and put it somewhere safe!

 

[Twister_Ken]

1.4 x sqrt lwl

In feet!

 

[ianwright]

Anything between 1.2 and 1.7 times the sq rt of the waterline, depending on the boat type. Fat and heavy one end thin and light the other.
