    This feels like one of those "if you can think of it, someone has done it" moments. Also, this is the sailing skiff version of a sleeper - make one that looks entirely stock above the water line, challenge someone in a Laser to a race, ruin their day.

    40 years ago I entered a race for Optimist hulls with unlimited sail area, but we didn't try foils, suitable material wasn't available. So I really enjoy seeing this working, in moderate winds.

      Windsurfers foil quite easily, its the size of the wing, the smaller the wing the faster needed to get up, but the higher top speed, bigger wing is lower top speed but barely any speed to get up

    People keep asking why do this to a 50 plus year old desighn. The point is to test and learn about foiling as a common sailing practice going forward. The opti is the most common sailboat on the planet so it is a great hull to prove the concept. Stock hull stock rig. Amazing results from the foil.

  • @Justin-vi8dr
    @Justin-vi8dr 2 ปีที่แล้ว

    It needs an aileron like the foiling catamaran i-fly has, wich always tries to correct the hull to a horizontal position when on foils automatically. Then it is easy for younger children to learn how to foil sail with these flying optimists.

  • @skyak4493
    @skyak4493 7 ปีที่แล้ว +1

    Great student project. I would also like to know if the hull is class legal. What does the boat weigh? It appears 5m/s down wind is near the lower bound for foiling. Is it possible to foil up wind in some higher wind speed?
    The obvious next step would be a larger more modern rig. The Clarks rig for the UFO is excellent for the price.

    • @Interdiction

    • @ncdave4life
      @ncdave4life 7 ปีที่แล้ว

      I, too, would like to know what it weighs.
      Obviously the foils aren't class-legal, but even if you removed them I'll bet the boat isn't class-legal. I'll bet it is way, way underweight.
      The minimum class-legal hull weight is 77 lb (35 kg). I'll bet this one is a lot less. (I don't know what the minimum class-level rigged weight is.)

      @EnniodBleu 4 ปีที่แล้ว

      That would be the ride height wand. Same system as a foiling Moth. It senses the water surface and adjusts the main foil trim accordingly to optimise lift and ride height above the water to take some workload off the sailor.

It would take a very stiff breeze to allow this to happen. You should take note that if these boats when tipped fill with water, it is all over till the tow boat comes. My dad, who built our boats would have been all over this if it had been thought of back in the 60s!
