By comparing sizings across all wave board fin configurations you are able to make informed choices especially if you are new to multi-fin boards or want to try something new to enhance your riding.

This data was complied by talking to wave riders of all from all over the world during a 10 year period. While there will always be exceptions to the rule, this guide acts as a great starting point.

As a general rule heavier sailors need bigger wave fins as do those who sail predominantly in onshore conditions.
