Down Wind In Light Air On O30
I have been asked to write about this so here are a few observations which
you probably all know about already.
Drive the hull and not the chute (this in all conditions). Sense the shifts in time to gybe on them; in superlight wind don't gybe. Don't overstand but in very light air edges and corners are good. Keep the crew weight as much as possible on each side by the shrouds, not in the cockpit. In superlight a little heel helps the chute fly, otherwise flat.
How to gybe in light air:
The main thing is to turn smoothly and with some appreciable angular velocity so that you can use the wind of rotation to keep the chute filled. This will cause a vortex which will require the main to be trimmed to a close reach (apparently overtrimmed) during the gybe and shortly afterwards. Advanced crew can also roll-gybe the boat effectively, but this is secondary to the turn.
To roll gybe, mid-boat crews should move quickly to throw their weight to the upwind side - when I do midboat I will crash into the lifelines there for extra oomph. This will kick the boat into an appreciable heel which turns it downwind while pumping the main and chute. Hold the heel through the turn until the boat reaches the new course on the other gybe and just as this is reached - hopefully the pole is just being made to the mast but if not, bow crew has to muscle it through this - de-hike smoothly to flatten the boat mast straight up, abruptly, which will pump the sails again on the new gybe. Do not pump the boat past straight up on the new gybe, both for rules reasons and because it is slow. Trimmers will know how to blow the old sheet almost to the forestay while trimming the old guy=new sheet back during the gybe so it is trimmed perfectly by the time the turn stops. Really good trimmers (like Bev and Hans and Doug on Aliens) will fly it perfectly through the entire maneuver, powered up all the way even in very light air. Bow crew needs to make sure the pole is pushed forward to the new tack immediately after hooking on - the karate move here actually helps trim the sail, just before the pole is made to the mast: hook, rotate torso to push it to tack, make it to mast. Next time you pass Aliens in light air you can buy me a beer!
