of a fin is what determines the area and the look. The way the area is distributed on the fin is what makes fins individual and work in so many different ways. A wide base fin with a wide tip is the most stable but not forgiving. A narrow base fin with a narrow tip will be very loose and fast but unstable at slow speeds.
The fin’s sweep
(or rake angle) affects the board’s ability to carve turns. A more vertical fin will make tight turns and fast directional changes while a more raked fin will carve wider arcs and handle more power through turns.
is also a factor in fin choice. Narrow tail boards do not require deep fins because there is less distance from the fin to the rail. A wide board requires a deeper fin than a narrower board. For example an 8’ egg style board that is on the wide side should use about an 8.5” to 9.0” fin. A narrow tail single fin board that is 7’6” can use a fin in the 7” to 8” range.
True Ames Surf Fins incorporate a constant foil
which means you will not find any flat spots on our fins that may cause water disturbance which will ultimately cause poor performance. Our bigger solid color fins are foiled from 7/16” solid 6oz. glass sheet stock. Smaller fins do not need to be so thick to have the proper foil.
