Interesting thread.
Tiddler is on the max engine size and hence a little stern heavy.
I spoke to the designer / builder who said that trim tabs would get her up on the plane at lower speeds.
I'm reluctant to start drilling and fixing tabs.
I wonder if a 4 blader would help on a titchy little boat?
If I get up onto the plane, and ease back to stay inside the harbour speed limit she begins to fall back off the plane. This sounds like prop slip.
Maybe I should be speaking to some of these propeller companies too ? ? ?
