I notice some replies don't show up, mine and other people's.

Bjorn,
You are very correct about the behaviour of HP when trying to turn hard.
If you put rudder (stern only rudder i used) over quickly, there is a big drag of water. Plenty of sound and kind of looks cool.
Trying to force long hull sideways through water.

I think you are right, this will probably inhibit ability to tack more than anything.
So little momentum, thay you stop moving before going through the wind.
Tacking is really like a parlour trick. Should be no reason do do so.
If you are in some situation without engine, can't anchor no room to shunt, current taking you over niagara falls....bad luck!
