MAX-PROP Feathering Sailboat
Propellers
DRAG
One of the most important feature of the Max-Prop is
that it feathers automatically with the forward momentum of the boat. Once
feathered, it provides the least possible drag (similar to a folding prop)
improving the vessel's sailing speed by an average of 15% above a conventional
fixed blade propeller.
EFFICIENCY
In forward: the Max-Prop will offer 96% of the
efficiency of a fixed blade propeller of the same diameter and pitch. The 4%
loss in power can usually be eliminated by precisely matching the pitch of the
Max-Prop to fit the boat engine combination.
In reverse: the Max-Prop provides 80% more power than a comparable fixed blade
propeller. The Max-Prop utilizes the same leading edge in forward as it does
in reverse giving the propeller the same thrust in both directions, whereas on
a fixed blade propeller in reverse the trailing edge becomes the leading edge
therefore reducing its efficiency by 50%
RELIABILITY
The Max-Prop uses a "differential" type design so
that the blades cannot fail to open in forward or reverse. This positive
system eliminates the problem associated with a folding propeller and its use
of centrifugal force to open the blades. In a recent survey of Seven Sea
Cruising Association readers the Max-Prop received a perfect rating on no
failures ( one of only two products to receive such high praise). About 32,000
Max-Prop are in operation today!
VERSATILITY
The Max-Prop offers the possibility of pitch
adjustment without external controls. Changing the pitch is very simple; it is
done by changing the setting of the gear inside the propeller (usually upon a
haul out). The ability to adjust the pitch will help achieve the maximum
efficiency from the engine without having to purchase a new propeller. On the
new V.P. model the pitch is adjustable externally.
INSTALLATION AND MAINTENANCE
The Max-Prop will fit directly onto your existing
shaft when the boat is hauled for installation. The Max-Prop will be matched
to your specific shaft taper and can even be
fitted on a Sail-Drive unit. The only required maintenance is to grease the
propeller at least every other year (all the new Max-Prop are fitted with
grease fittings).

RACING
Worldwide, many of the top racing boats have opted
for the Max-Prop solution.
CRUISING
The two or the three blade Max-Prop is the propeller
of choice for the cruising sailor. The combination of low drag, increased
speed, outstanding backing power, safety and maneuvering, and fail safe design
makes the Max-Prop the ideal cruising propeller.
