Mmmmm, very interesting. I knew that the speed of a displacement hull was limited i.e. a bigger engine doesn't mean a faster boat, now I've learnt the 'theoretical' formula.Peter B said:Sorry desy, I forgot to tell you. The theoretical maximum speed for a displacement hull is roughtly 1.34 x square root water line length.

Is your boat a Tidemaster or an Orkney Longliner? There's a bit of a difference!!!
My last post gave you the basic hull shapes, and that's what matters, so have a look at your hull, whatever make it is, decide whether it's a full displacement or a semi-displacement and take it from there.
