Boat design and hull shapes

Fin (skeg)

Also: skeg, tracking fin

A fin is a blade under the stern. It noticeably improves a packraft's tracking.

According to the Anfibio blog, a fin mounted centrally at the stern gives the strongest directional stability. Side fins mainly help against drift when sailing; a bow fin can be useful in strong headwind. A fin should never be fitted directly to the flexible floor.

The fin is slid into a mount before inflating and then sits firmly. Since 2022 all Anfibio boats have a fin mount from the factory; for older boats there are glue-on mounts.

Warning: in shallow or rocky whitewater a fin gets in the way and can be torn off. On the Anfibio Revo, fin and drain tube must not be used together; the tube is then pulled inside.
