I just purchased a Funster 205 for teaching kids and beginners and took it for a spin with my Severne NXC 7 and found it suffered quite badly from cavitation and was very difficult to recover. I was not using the centreboard at all and wonder whether I should use a much bigger fin that the standard one supplied with the board. It was not particularly loaded either so I was a bit surprised it was so bad. I had to completely stall the board to recover.

I have a bigger fin from another board, that I have never experienced cavitation with, that I could try.

Just wondering whether I am just expecting too much because of the board size or whether I should expect and improvement using a bigger fin.

The Funster 205 is a bit like flying a boeing, recovery from cavitation is probably a bit like trying to recover from a stall in a boeing as well - near impossible...

Cheers

^^^^^ agree, fin supplied is just for learning. I suspect it was designed to be trashed, so anything better was a waste of money and effort. Go a good quality 40 and above if you want to play on it.
Grandkids reckon the board is great to play and learn on, as its easy, wide and stable to use.
