Single pair installation
Humphree fins comes in six different sizes to fit your vessel:
0.40m2 0.60m2 0.80m2 1.00m2 1.30m2 1.50m2
A slightly bigger fin will improve the zero speed stabilisation, which is recommended if the vessel has a top speed below 35 knots.
All fins are designed to suit our fast SU-553 electric servo unit.
The chart below gives a general picture of recommended fin sizes. Certain boat types may require other solutions. Please contact your nearest Humphree dealer for advice.
