Hey Pete have you tried going to a smaller board ,when you sail feels big ?
why I ask is the other week I was on my 110 Patrik with a Maui venom 7,0 which it handles nicely
I was starting to bounce a little as the wind came up ,too stuffed to change sails ,so switch to a smaller 100 litre Exocet slalom board ,because it was a smaller surface area the extra power of the 7,0 could escape easier through the board ,so it didn't feel as draggy .
and it was easier to handle .Speed also increased .
The Mauis are very light for their size ,I have the 100 venom mast to suit it ,it also has 8 battens .it feels lighter in the hand than my 7,0 SCR simmer 8 batten race sail that has torn and broke battens

big crash .simmer to me was a faster sail ,but heavy built .
