Fin guide

Twin installation

Humphree fins comes in five different sizes to fit your vessel:

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.

The 0.60-0.80m2 fins are designed to suit our fast SU-553 electric servo unit. The SU-563 servo is developed for the larger 1.00m2, 1.30m2 and  1.50m2 fins.

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.

Quad installation

The Humphree fin system can be configured with 4 fins operating as an integrated system for bigger vessels.

The system will synchronize the operation between them without the need of extra configuration, just plug and play.
