Double Spinn Sheets
I thought I would give my 2 cents of knowledge on Gybing with 2 sets of sheets and guys. Having raced on a variety of race boats, the most powerful, but yet elegant and easy to use is that of a Modern 12Meter "Fiddler" Ex. America II US 46. I will review this from both the stb. trimmer to the port trimmer.12Metres and IACC boats both utilize only one (1) winch on each side for trimming any foresail. They utilize a mechanical or hydraulic clutch to lock the sheet, located between the turning block at the transom and the winch.In addition the winch has a lower free turnning drum. It works like this.
You are the guy trimmer, as the boat turns downwind, if we came off a vmg run, the guy trimmer trims both the guy, as the pole comes aft, and the sheet. Just before the "trip" you lock off the sheet and quickly remove the guy from the drum, place the new sheet on the winch and un-lock the clutch, you are now on the sheet.
You are the sheet trimmer, as the boat turns toward dead downwind you slowly ease the sheet so that the leward clew is even, or beyond the headstay. You allow enough slack in the lazy guy so that the bowman can reach the bow + 1 foot. At the time of the trip, the pole comes through the foretriangle, you lock the sheet and quickly remove the sheet from the drum and replace it with the lazy guy. As the bowman yells made and the mastman is jumping the topping lift you trim the new guy as fast a you can. When the pole is in the right position, you unlock the sheet. You are on the guy.
