SPS55 stabilizer actuator kit

SPS55 stabilizer actuator kit


The new SPS55 actuators for the Vector fins™ are incredibly compact and silent, designed to fit in the small available spaces in modern boats below 20m/70ft where living space is strongly prioritized.
The SPS55 actuators have been designed to satisfy the needs of owner operated vessels with a total focus on reliability and hassle-free operation, as well as ensuring a quiet operation as they will mostly be installed below the floor in living spaces.

SPS55 Features

Technical design benefits:

  • Squared base plate provides large load distribution area to hull while still being possible to install in tight areas between stringers and bulkheads. 
  • Dual, balanced cylinders provide symmetrical load and force.
  • The actuator can be installed in any direction in the boat, the fin angle is totally independent of actuator direction.
  • No moving hoses at all secures against leakages and potential wear, as well as making the installation easier.
  • Oversized bearings for lifetime operation with only a minimal level of maintenance. 
  • Rack & pinion drive connection for quiet,  reliable, long life operation, with very easy service when needed after thousands of operational hours.
  • Fins are installed and removed very easy and quickly from the outside for best convenience in for example transport or other haul-out situations where this might be needed.
  • Defined shaft-shear point in case of the fins accidentally hitting something.
  • All wet parts in stainless steel.
