Select the right Thruster

Whether it be a tunnel or a retractable thruster that suits your needs, choosing the correct thrust rating (or relative power) is important.
To help simplify the complicated calculations associated with the many variables in yacht design, we have designed the following charts:

Tunnel Thusters

 

Retractable Thrusters

 

To use these charts there are two factors (excluding the length of your yacht), which you need to determine:

      

1. The relative size & wind area of your yacht
For a yacht of any given length, the area it offers to a direct side wind can vary from one design to another. The underwater shape & total weight can also differ greatly. However, most pleasure craft, both motor and sail, will fit into one of three categories:

 
Cruising
Fast cruising
Super fast cruising

 

2. The conditions in which you use your yacht (thruster force required)
Different people have different uses for their yacht. An expedition yacht on a world cruise would have different needs to a picnic boat berthed on a lake. In brief, some people would like a more powerful thruster than others. If the size of your yacht intersects more than one thruster on the selection chart, the choice of thruster will depend on the situations and conditions in which it will be used.
