The Video:After 2,800,000 views of Ray's videos, the question is, what is a hydrofoil? The High Flying Banana is used to explain why it is more like an airplane than a boat. This is a quick preview of Ray's book "Creating Hydrofoils" now available at Amazon.com

  • The reason hydrofoils have not caught on is because of bananas.

  • Hydrofoil downsides? how strongly are they mounted? Some need high sustained speeds. Some when they fail, fail catastrophically. Sometimes propulsion systems need to be modified.  Protruding foils increase draft, But there are a lot of advantages depending on how you design your hull. Speed loss due to cavitation is all about how a foil is finished. Usually if you have the power to go beyond 60kts, which is the cavitation limit and the foil has a mirror polish, you should be OK up to 100mph

  • This guy is funny! (XD>

  • Hi. Very nice discription of hydrofoils.

    This question has some value, i think. Why is not everyone using this. What I know is they have a speedlimmit befor cavitating, when the wing wil loose lift. My question: What is the down sides of hydrofoils?

    Ones again, nice vidio.

    Best to you. I hope your book will sell. (what is the title).

  • Great meeting to you and your wife at Jim's the other day, the video is great and would love to see more of what your up to :-) from Diana and hubby Steven Baker

  • @breg77 The ability to smoothly cruise over rougher water. There's also less drag, so the fuel economy is greater.

  • Looks cool - but what is the real advantage over a conventional boat? If it is speed - are there any figures, like comparision based on the same payload and engine?

  • time to get some new sunnies Ray. dude

  • Could you be my tutor captivating never learnt so much in such little time

  • What hp is your engine pls?

    Thanks

    Eugene
