Sailing/Racing Frost Bite:

You got to be Nuts to sail in the winter - and I am!
Frost Biting brings out the best sailors who just can not stop sailing.
Courses are short, races are fast and you try for as many races as time allows.
I would races Lasers in the morning and Dyer or O'Donnell dingy's in the afternoon.
Chicago YC @ the Belmont Harbor and Severn Sailing Association have Frost Bite programs.

O'Donnell dingy, two man club boat. Slow uncomfortable but the fleet was identical. With no boat speed Tactics was the key to winning.
Dyer boats replaced the aging O'Donnell's with a one off design for CYC.
Starts were three minutes, and the starting line was short. Note the yellow mooring cans still in the harbor - many a boat's mainsheet snagged these cans.
You must get a good start and at the favored end of the line. Within 30 seconds of starting you knew how you would finish.
Upwind work holding both tiller and mainsheet in one had while adjusting down haul.
Roll tacking, hit every shift, work the boat, feather in puffs. Frost bite sailing honed these skills.
Rounding the windward mark. One boat length here marks the difference between a third or near last place.
Reaching - when the puff hits you take off, you keep the boat flat and pump the main to stay on the plane.
Downwind notice the vang and boom bend. You can see the tiller extent ion is taped so a wet hand wont slip off.
Same as above - the boat is flat, weight is aft and in this case the boat is level. You can go faster if you heel to weather - but watch out for the death roll.
The start of a death roll. Boat is heeled to weather, lots of vang and I am moving fast. Puff hits and I start rolling to weather. Four images in this gallery group.
