LEWMAR retractable swing thrusters

LEWMAR retractable swing thrusters

Using this innovative system, the propeller is only immersed when neccesary, without taking up excessive cabin space, as is common with vertical systems. During manoeuvres, the swing thruster guarantees a 30% superior performance when compared to the thrust from conventional tunnel thrusters of the same power rating, because the propeller is deeper and positioned right at the bow. The vessels performance underway is not compromised, because when not being used, the tunnel retracts inside the hull.
