Should a heavier rider use a different fin compared to a lighter rider?

Yes, he needs to. Heavier riders need to use 2cm to 4cm longer fins then a normal sailor. This is why we really do not have fin charts on our website. Everything matters from the board litres, sail size, your weight.

We receive many emails from customers that ask for help on choosing the better fins combinations for their boards. I personally respond to everyone…We consider standard weight up to 80/85kg. Then you start to become an heavier sailor.

The gear that a 100kg guy uses in strong winds is definitely good in very light winds for a 65kg sailor. The reason why is the board volume and the sail size.

The 65kg sailor will be able to fly with light winds since the board will float more and have more lift, but as soon as the wind will increase he will have problems in controlling the board due to his body size.
