Your way to the right GORI folding propeller

Discover the world of high-quality GORI folding propellers, specially developed for sailing yachts. Learn about the unique features that make GORI propellers an excellent choice. Especially the 3-blade variant is extremely popular due to its optimal reverse driving characteristics. The GORI RACE, on the other hand, features an unmatched low drag resistance, making it the best choice for racing yachts.

Step 1: Choose the Right Model - the Propeller Calculation

Find out how to determine the right size and type of propeller based on your boat type and engine power: the right selection is crucial for performance and efficiency. GORI Propellers are available as GORI 2-blade propellers, GORI 3-blade propellers and GORI RACE 2-blade propellers. All propellers share their high-quality workmanship and low drag resistance, they only differ in detail.

For your propeller selection, first use the manufacturer's calculator. Doing this, the most important data are the total weight of the ship and the engine modeltogether with the maximum revolutions per minute and the gear reduction. The propeller calculation subsequently estimates the optimal GORI folding propeller for your boat.

For an initial selection, you can find a selection proposal here for many common series ships.

Overview of Series Ships

After the calculation, you will receive a recommendation email from the manufacturer for both a 2-blade and a 3-blade model, possibly with safety warnings. Simply forward this email to us (info@mare-sports.com) and we will be happy to advise you.

Here are the most important notes on the different propeller models in advance:

GORI 2-Blade Propeller - the standard propeller from GORI

The GORI 2-Blade is the model with the best price-performance ratio. It combines good forward and reverse manoeuverabililty with a reduced drag resistance and easy installation.

GORI RACE 2-Blade - the High-End Folding Propeller for Racing Boats

The GORI RACE folding propeller is optimised for racing boats: optimal sailing characteristics due to an extremely low drag resistance, but with disadvantages in reverse manoeuverability under engine. The GORI RACE is used by numereous offshore racing teams and is especially favorable under ORC and IRC rating rules, where the advantages of the reduced drag resistance are not or only barely punished.

GORI 3-Blade - Unique GORI Technology (with or without Overdrive)

The GORI 3-blade folding propeller is the flagship of the Danish company: it combines minimal resistance whilst sailing with maximum thrust under engine. The folding blades can pivot 180°, thus offering the same pitch and efficiency in forward and reverse mode, giving you the same thrust and excellent manoeuverability in both directions.

The optional overdrive mode of the propeller increases the efficiency: the propeller delivers the same thrust at a lower number of revolutions, resulting in less noise, vibrations and a better fuel efficiency.

The GORI 3-blade folding propeller is available in different sizes and suitable for a wide range of engines up to 300hp.

Step 2: Request a Personalised Offer

After you have forwarded us the results of the manufacturer's propeller calculation (or your ship data), we will check the data present to us and especially the safety warnings. In doubt, we may also contact the manufacturer. Once we have clearified all the details, you will receive your personal offer by email. We are also happy to advise you in advance by phone or email if you have questions.

Step 3: Check Technical Details

Check whether the dimensions of the chosen GORI folding propeller will fit onboard. Does the propeller fit between the shaft and the ship? When folded , is the propeller possibly too close to the saildrive or rudder?

Step 4: The Ordering Process

Once the technical check is done, your order can be placed. Some standard models are available from stock. Normally, your individual propeller will be with you in latest 3-4 weeks.

After Purchase: Installation and Maintenance

For installation, we provide you with installation instructions and maintenance notes. Maintenance kits with new anodes suitable for your propeller can be found here. Depending on the sailing area, our own experience suggests that painting the propeller with Propspeed may be recommended after a few years.
