The 2-blade Gori folding propeller is for sailing yachts fitted with engines up to approximate 60hp (44kW). It is available in 7 diameters from 11.5" to 18" for shaft installations and Saildrive. RH and LH rotation.
The geared blade design ensures blades open and close together
giving less vibration ahead and astern. Under sail blades close
simultaneously removing the need for elastic bands.
Why not an extra knot?
Under sail, a fixed propeller slows a yacht much more than most
people would imagine. Tests have shown in certain instances that
the 2-blade Gori folding propeller reduces the yacht's total drag
by 35%. This resulted in one full knot of improvement in speed
under sail. A folding propeller as opposed to a feathering
propeller does not snag seaweed, lobster lines or plastic bags when
sailing.
Full power ahead
Tests have shown that the efficiency of this propeller in
forward is better than most 2- or 3-blade feathering and folding
propellers.
Full power reverse
Tests have shown that the efficiency of this propeller in
reverse is equal to or better than most 2- or 3-blade fixed,
feathering and folding propellers. The Gori propeller gives you the
optimum thrust in reverse by virtue of its propeller blade shape
and profile, and does not rely solely on the centrifugal force to
open the blades as do many other folding propeller types.
Saildrive
The hub of the Sail-drive propeller is manufactured with a
flexible bushing that absorbs shock and electrically insulates the
propeller from the Sail-drive leg.
