These previous discussions have links to papers and videos that are convincing. The sound reduction is astounding. The power graphs are impressive. The price of the boat propellers is gobsmacking… but if the efficiency claim holds true, will easily pay the upgrade, and the dolphins & whales will be ever thankful.
- zawy 4y agoBe careful of the boat propellor claims. For example, they filmed the regular prop in slow motion to hide that it was going at a much faster speed that caused more cavitation to make it look worse. Also when they claimed it needed a LOT less steering, I'm extremely skeptical because that should be mostly caused by the boat riding higher in the water at a faster speed. Also they disabled comments on videos. https://youtu.be/_KkIqC7arnU?t=74 https://youtu.be/_KkIqC7arnU?t=74
