Have a look at the bennetttimtabs.com website. Leastways I think that's what it's called. There might be some advice and help there.

The square root of ;-total shaft horsepower/weightxconstant=speed.

If it's on a US site, then I'd put my money on it being in imperial units, so feet and inches, US gallons lbs etc.

Buit don't hold me to it.

You're right; there's no way it'll be metric. They can't even pronounce it

Are you talking about fixed tabs just to increase the waterline length or adjustabe to correct trim level and wind lean ?

I don't think you meant to ask me, but IMHO, it would be the latter reason.

 

[stamfordian]

Your right the latter,
