You're thinking dinghy style... If you reason windsurf style the board gybes under the rig and the rig only comes back online once the board is planing on the new tack, so you don't let go the sheet so to speak, you actually sheet in going into the turn. So, what would happen with a dinghy would be the difficulty sheeting into a bear off, then there being enough sea/water room for the boom to pass the initial phase of its travel without grounding down, that's the bit that is more concerning. |

Where is the problem powering up after a gybe? The boat is moving forward, it gybes, you sheet in and 'catch' the wind on the new tack. If it is windy you let the sail flap then sheet in when you feel safe. The trick is to get power immediately by controlling things. Like I don't. How is hauling yards of mainsheet in to pull the boom back from in front of the boat better or safer?

I think one big issue is that IMHO we are not really sheeting in after a gybe on a board, in effect. We tend to pivot the entire rig around a point about mid way down the boom as we sheet on, IMHO. We pull the mast a significant way to windward and then let the mast and luff fall away, using our back arm as the pivot point. Rather than pulling the back hand in while loaded to get the right sheeting angle, we are essentially letting the front hand out in order to get the right sheeting angle. In boats we can't pull the whole rig into the turn in this way and therefore we don't have the option of gybing this way.
This is just my own belief, from re-playing board gybes in my head and also from the fact that when I am coaching people in longboard high-wind gybes, I really stress that the idea is not to sheet the back hand in, but to let the front hand out. Sheeting the back hand in creates the same sort of problem that Laser 173XXX identified. Sheeting in a dinghy makes it even harder and MM has identified the issue and the way that Grumpf could test it. I've tested this numerous times by losing the mainsheet knot in a Laser and trying to sheet back in with the rig streaming over the bow after I've re-lead the mainsheet. ![]() Yes, you can turn a dinghy so far that there's not much force in the main after the gybe - we even used to do it on offshore racers. But as iiitick noted, you can do that with a conventional setup too.

Equally daft idea.....Boat sailing downwind displacement sailing and pushing all that water aside wasting energy to do it. How about storing some of that energy (say a tube with a turbine in it passing through the boat), then farting it back out again at moments of tension like approaching a windless mark or a race to the line. Energy stored by inflating bags.
Anybody else as bored as me?
