Our clean and simple rake center fin is perfect for any performance longboard, especially our Redline and CMP models. Fiberglass fins hand-crafted in the USA by Rainbow Fin Co.

Here are our general recommendations for each size fin. 

6.0" center fin with side bytes - mid-length boards 6'6 - 8'6

6.5" center fin with side bytes - longboards 9'0 - 9'6

7.0" center fin with side bytes - longboards 9'6 - 10'0

7.5" or 8.0" center fin with side bytes - longboards over 10'0

This is of course dependent on the surfer -- a smaller person could use a slightly smaller fin and vice versa. Feel free to call the shop to chat about what fin would be best for you and your board.

***Please note, all of these fins are HANDMADE by Rainbow Fin Co. and there will be variation in the color from what you see on your screen vs what is received. We do our best to photograph the fins to represent the actual color, but they won't be an exact match. We do not accept returns based on color variation.***
