A boat designed to jump-particularly with a foil to cushion re-entry- is likely to be a lot of fun. Moths don't jump-intentionally- because they have wands. When a Moth gets high enough for the main foil to come out of the water the bungee pulls the wand all the way forward raising the back end of the flap resulting in a virtually instantaneous crash as the boat re-enters. This kind of crash happens often,particularly with bow mounted wands, in conditions where there are waves.
If I am correct in my assesment of the Howes foil the result of re-entry is likely to be more like the re-entry of a foilboard-and the jump done for the pure fun of it.
