Max Power publish a guide for selecting the correct bow thruster for your boat or yacht by Length Overall and Displacement

Max Power Bow Thruster Model Guide

There are other factors that will affect your interpretation of the guide other than length overall. There are three different options in the chart to make allowance for displacement - cruising, fast cruising and super fast cruising.

In addition, you will need to take the following into account in order to assess the thrust required for your individual yacht and circumstances:

  • Windage - the area that is presented directly to a transverse wind
  • Water resistance - the depth and breadth of water that will need to be pushed by the thruster
  • Underwater profile - the shape of the keel will directly affect the thruster's ability to move the bow e.g. a yacht with shallow draught fore and aft may readily pivot around a short keel while a longer deep keel will need a lot more thrust capacity
  • Desired maneuvering ability - select a thruster by interpreting the chart, left or right, according to your anticipated usage and your expectation

Replacing an existing Max Power product is a relatively straight forward task. The main units should slot into the existing tunnels without issue. Replacement cable, switches, fuses and holders are also available to service your existing set-up. Datasheets and Installation Manuals, including a troubleshooting guide are available to download for all models

If your boat does not yet have a tunnel thruster, Jimmy Green Marine recommend getting a professional boat builder to perform the initial cut out and installation of the tunnel. New GRP tunnels are available from us to suit the unit but they do require additional glass fibre work to be securely fitted.
