MARINE ENGINES INSTALLATION
The advantages offered by this solution are:
■
More habitable space inside the hull
■
Better power efficiency, despite the lower mechanical efficiency, since the propeller axis is parallel
to the travelling speed
■
Good manoeuvrability at high speeds, enabled by the simultaneous rotation of the foot-rudder and
the propeller
■
Possibility of correcting the boat trim as a result of the adjustment of the whole astern foot slant
■
Installation simplicity offered by the lack of the axis line, bottom tightness and tailpieces
■
Noise and vibration problems which can be solved more easily
The drawbacks are the following:
■
Boat design for the installation of the astern foot
■
Poor boat manoeuvrability at low speed
■
Unsuitable use on displacing hulls
“S” drive (sailing boats)
It is a propulsion system for limited powers used as an auxiliary unit on sailing boats. This unit, similar
to that with the astern foot, consists of an engine and a drive fitted on the appropriate base support-
ed by the hull bottom.The foot is usually fixed and for the route changes it is necessary to use the boat
rudder; in some cases the whole wheel unit carries out the rudder function.
The propellers used are usually fitted with foldable blades to reduce the resistance to the sailing
progress.
