Single fins pivot like no other fin arrangement. I’ve used this advantage to make a really manuverable small-to- medium-size wave monster.

This isn’t really a “retro” style board, but it has a rocker and thickness distribution that helps a single do what it does.

Pictured here is a 5”8, 14 3/4 X 20 X 15 7/8 X 2 1/2

Comes with a high rake
