[hpv-boats] Planing Stabilisers

You are right about the stabilisers operating primarily with dynamic  
lift at typical operating speed because they are very lightly loaded.

I consider the shape I have arrived at hard to better for all round  
performance.  There would be advantage in being able to trim the  
height when in operation but mine are set at a suitable average.

Wide transoms on planing hulls actually suck the stern down at semi- 
planing speed so readily trim bow-up and then provide a high aspect  
lifting surface at the transom when at high speed.  So they are  
beneficial where there is a lot of power to get on the plane and then  
operate at high speed.  A wide transom would not offer any benefit on  
my stabilisers and would add extra drag when pushing through waves.
