I dont think the Gybing boards have taken off to be honest! I have only seen a few boats with them fitted and it looks a bit OTT for me!

A gybing board is a system where the board can twist slightly in the case so that its not exactly in line with the boat.
Normally a dinghy sails along ever so slightly sideways (which we call leeway) so hat the board is at a bit of an angle to the water to provide lift. If the board is set up at the right angle then the boat appears to have no leeway. Whether, how and why this works in making the boat faster is a suprisingly complex question, and I have seen no answers I regard as completely convincing. There is a big thread about Development Canoes on SA at the moment which discussed the subject at length. On that subject can anyone think of a single sail class that has tried out gybing boards, and if so how did it work? |

The Lark class has gybing boards on older boats but I'm not sure if there the same as the I14 and hornet. They just allow the board to move in an oversized case in the older boats the newer boat apparently have tighter cases so its not done.
Looks a similar idea as the hornet. Edited by foaminatthedeck |

Gybing boards normally need to be a centreboard rather than dagger
system. I tried them on a sailboard many moons ago, they have an offset diamond on the head which when actuated by pressure points the leading edge higher into the wind, but they also have a small "knock" section that if you kick the plate back a bit, it returns to centre and fixed. They work great in light weather, but stalled the board terribly in anything over 10 kts. O.K. that's a round sailboard with an un stayed rig, so it might be possible to power through that with a couple of guys on the wire, but it could explain why they never caught on. |

I was reading somewhere that someone tried a gybing board that only gybed on one tack, i think it was only on starboard tack that it gave the advantage. I could be wrong. |

Needs to sail more...
