Thanks a lot Skymax, great information as usual.
I particularly enjoy it wet n wild and will take the Turbo fins out next time. Never thought about plugging the plug! That's my plan now for the weekend.
What do you mean by the term 'fulcrum'?

Goodo, if you cant get Neoprene any carvable rubbery compound will do.
A following swell lifts and pushes the boat and it picks up speed temporarily, if the boats stern is at an angle to the pushing swell direction then the drive fins will create drag forward of the CG and the hull will want to rotate around the axis where the Drive fins are, (to some extent, even if in the UP position), like a lever on its side with the Fins as the turning point, or fulcrum. This can be corrected with Rudder but energy/speed/time is lost.
In other words with wind and wave astern, the Drive fin drag at the front of the boat will sometimes want to make the Stern catch up with the Prow, and you get that, "Sideways in the Driveways" feeling..
