My thruster is made by the amel factory.
it drops down with a section of the hull
when in use and retracts when not in use. in the retracted position it is flush with the hull
and it is difficult to see even when the boat is out of the water
Kimberlite is 28 metric tons displacement
i use the thruster for short bursts of about 5-10 seconds.
longer continious use will smoke the motor
what do you mean by the square footage of my boat?
it is a 53 foot ketch
