For cruising and regatta sailingA folding propeller is suitable for almost all sailing boats that have an internal engine. You will therefore come across propellers that are used all over the world by professional as well as freetime sailors.When the engine is switched on and the propeller is turning, the blades unfold due to centrifugal force. This also applies at very low speeds and even in reverse, as the centrifugal force is always stronger than the water current.In the passive state, the propeller does not rotate and is therefore not influenced by the centrifugal force. Instead, the blades fold together due to the water pressure. This creates less resistance, so that you can sail even in low winds. the folding propellers therefore fold up due to the natural centrifugal force when the boat`s engine is running.However, the Flexofold folding propeller is not only effective when the engine is running, but also when the blades are pushed back by the water current.The benefits of the Flex-o-Fold:Very low drag resistance - high thrust for motor driveGood manoeuvrability - outstanding forward, stop and reverse performanceIntegrated shock absorbers minimise impact when opening the bladesSmooth-running gears and robust materials - long service life without the need for lubrication, rebuilding or other maintenance workHelical gears between the blades ensure synchronised folding mechanismFastening screws are pre-coated with Loctite - can be mounted both above and below waterWater-lubricated - no maintenance requiredAvailable for shaft system and saildrive2-blade Flex-o-Fold Folding propellerPropeller diameter: 13" - 18", 330mm - 457mmFor shaft-ø 25-30mm or saildrive If you have any questions or queries, please call us on +49 471-77047 or by email info@spw-gmbh.de.For any final clarifications, please let us know your telephone number when you place your order.
