2-blade Gori folding propeller

The 2-blade Gori folding propeller is for sailing yachts fitted with engines up to approximately 60 HP (44 KW). It is available in 7 diameters from 11.5" to 18" for shaft installation and Sail-drive. RH and LH rotation.

GEARED BLADES
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 the 2-blade Gori propeller in forward is better than most 2- and 3- blade feathering and folding propellers.

FULL POWER REVERSE
Tests have shown that the efficiency of the 2-blade Gori propeller in reverse is equal to or better than most 2- or 3-bladed 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.

SAIL-DRIVE
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, as required by the engine manufacturers. The propeller fits most Sail-drives, for example: Bukh, Sonic, Volvo Penta incl. 50S-drive and 100S-drive, Yanmar and others.

The racing series folding propeller

Gori propeller is developed from our experience in supplying the world's leading yachtsmen, many of whom achieved firsts in Admiral's Cups, Whitbread Round The World Races and other major events.

The design and shape of the propeller give absolutely minimum drag when folded, and a fine effect under engine power. The well-known system of geared blades is used on the racing series, but the shape of this fully-closing folding propeller secures low drag and the blades stay closed when sailing. Yet still open under engine power.

The racing series of folding propellers is offered to racing yachtsmen all-over the world in 7 sizes ranging from 30 footers to Maxi Raters, and for shaft installation as well as for Sail-drive and Hydrodrive.

Model               Diameter    Typical Boat Size
375 Racing      375 mm       30 footer
380 Racing      380 mm       Mumm 36 approved
425 Racing      425 mm       40 footer
375 Racing      375 mm       30 footer
475 Racing      475 mm       46 footer
530 Racing      530 mm       Whitbread 60
680 Racing      680 mm       IMS Maxies
Maxi Racing    750 mm       IMS Maxies


Actual propeller size depends on boat and engine installation.

Custom-made propellers available.

3-blade Gori folding propeller

The 3-blade Gori folding propeller marks a technological and functional leap forward in the development of propellers for sailboats. It is now possible for sailboats and motorsailers to gain the folding propeller's speed advantages under sail, combined with the fixed propeller's thrust capability when motoring. The 3-blade Gori folding propeller was introduced on the market in 1994 and won the DAME award and HISWA award the same year, as the best new marine product.

"OVERDRIVE" FUNCTION
The 3-blade Gori folding propeller's "overdrive" function adds a new dimension to sailing under power. The helmsman can choose the propeller pitch and profile in the water while sailing forward, by regulating the yacht's shift and throttle control. Without the use of vulnerable hydraulics or complicated mechanical devices.

The "overdrive" is used when motorsailing in fair weather or when using the engine under sail. The "overdrive" gives the same speed at lower rpms. The result is less engine noise, less vibration and better fuel economy.

The function is simple. E.g. when changing from "overdrive" to normal ahead the shift and throttle control is set in neutral, which allows the propeller to fold. Then the shift and throttle control is set in forward again.

The propeller in itself adds a new dimension to sailing under power. Qualities that are unique to the 3-blade Gori folding propeller.

FULL SPEED UNDER SAIL
Folding propellers have been reserved for small and medium size sailboats with moderate engine power. They have been able to obtain under sail the extra speed the folding propeller allows by the minimum drag.

The 3-blade Gori folding propeller brings these advantages within the reach of larger sailboats and motorsailers. The extra speed under sail is substantial. The design prevents seaweed etc. fouling on the propeller. A further potential for optimum speed.

Tests by major yachting magazines have shown that the 3-blade Gori folding propeller has a much lower drag than any other well-known 3-blade sailboat propeller, no matter if it is a folding propeller or a feathering propeller.

EFFECTIVE FOR ENGINES FROM 10 HP TO 300 HP
(7 KW - 221 KW)
The propeller revolution for larger sailboats and motorsailers is emphasized by the fact that the 3-blade Gori folding propeller can be used for boats fitted with engines from approximately 10 HP (7 KW) and up to approximately 300 HP (221 KW), and the power transfer is on the whole the same as for fixed 3-blade propellers. The design of the Gori propeller results in minimum noise and vibration, which is often a problem for the well-known types of feathering propellers.

The 3-blade Gori folding propeller is offered in diameters from 15" and up to 30".

Tests by major yachting magazines have shown that the 3-blade Gori folding propeller has a much better efficiency both forward (+11%) and reverse (+6,5%) than a feathering propeller.

EFFECTIVE FOR ENGINES FROM 10 HP TO 300 HP
Professional quality
Gori propeller has for more than 20 years been leading the field in development of folding propellers. The 3-blade Gori folding propeller underlines Gori propeller's technological leading position, which is protected by patents pending.

The 2-blade Gori folding propellers have for over 20 years proved their superiority and quality. They have been a natural choice for boats exposed to the most intense strains, for example during the Whitbread Round the World Race.

The 3-blade Gori folding propeller is manufactured in the same professional quality, where every single propeller has its own number and a "logbook" during production. Each propeller is balanced dynamically.
