If you have a spi pole there is nothing to stop you using that to increase the angle that you can fly the thing.

As for gybing I STRONGLY recomend dousing the monster with the sock, gybing then trimming the sheets and relaunching. Getting the monster wrapped around your forestay or furler is no fun. Ask me how I know this.

What's the worst that could happen?

Dousing before gybe probably makes sense in a 44' boat. Unless there's heavy air, I won't bother doing that on my 36' boat.

An earlier posting asked the question "What's the worst that could happen?". I'm sure there's much worse, but before I was accustom to gybing I had an issue. We were on the Michigan side of Lake Michigan, just before sunset. It was May and the water was around 42 degrees. Home port is the Wisconsin side, about 12 hours to the west. I had lots of hours on a similar sail on a 25' boat, but unaccustom to it on a 36 boat, I lost track of the lazy sheet and it ended up overboard and wrapped up on the prop. We couldn't turn on the engine with it wrapped, we couldn't sail into an unknown port at dusk w/o the motor, so we turned west and sailed all night back to Wisconsin. Then back on the Wisconsin side at dawn, about 5 miles offshore, the wind died and we were parked. Without many alternatives and not wanting to wait 10 hours for the wind to come up, one of the crew volunteered to jump into the icy cold water and cut the line.

Since then I've been pretty careful to take care of the lazy sheet. I generally do a couple of wraps of electical tape to hold it to the lifeline. When we gybe, the tape breaks away, but until then the line is prevented from going overboard.

Attach tack in front of the jib furler. The head is hoisted by the spinnaker halyard. The two sheets go in front of the forestay and back to the jib winches. The chute is gybed by pulling it across, in front of the forestay.

The sock when the spinnaker is deployed sits at the top.

Do you leave the sock hoisted, and the whole thing in the sock, when it's not in use, and then deploy it - or keep the whole thing below and hoist it when you're about to deploy it?

Interesting idea. I might give that try.

Right after the gybe is completed I check that lazy sheet is over the pulpit.

I have only ever wrapped on spin sheet, we had a short sail back to calm water. One crew member donned a wet suit and googles and we unwrapped it, not cutting necessary.

Same here... in September off Samsun Narrows. My brother managed to free it without a wet suit... we ran low on Rum that day!

One solution to the matter of wayward assym sheets is using a single continuous sheet which reduces the need line length by about 1/3rd. We us a single 3/8" spectra sheet with the cover stripped for the last 15' on either end. This is led to through turning blocks on the aft quarters then, on each side, forward and around the headstay but inside the assym tack line (because we usually do "inside gybes") and then secured to the sail's clew. The loop of line in the cockpit passes in front of the helm between our spinnaker winches. Organized in this manner, the lazy sheet is never lost.

FWIW...
