The Hoist (I am no expert this is what works for me)
After rounding the windward mark I make sure that i am clear of traffic and if needed will jibe to get clear of traffic if needed.
Then I head straight downwind or close to it and travel all the way out with the main still sheeted hard to provide support for the mast. At that point I move forward and towards the middle of the tramp, this puts me in a good position to pull the halyard. Also I can tuck the tiller extension under the back on my knees which allows me to hold the boat at the course I want. Then I hoist the sail, it only takes about 4-5 seconds.
Once it is to the top I move back and begin trimming, I worry about the spinnaker before i get the main and jib back in tune just because it is the powerhouse downwind and i feel like it gives the most immediate speed. Once it is trimmed I trim the main and jib,
the main you have to keep sheeted hard to support the mast, but you will be surprised that is what the sail wants because the speed the spin adds will bring the apparent wind way forward. So basically the sail is in upwind configuration other than I release the outhaul to provide extra depth to the sail and stay traveled out based on the angle I am running.
The jib also will be trimmed in pretty tight, but not quite to upwind trim, just watch the tell tales, I just get it close and then don't worry about it, the spinnaker is the only sail I trim going downwind.
To depower and power-up I either bear-away or head-up. That was one of the hardest things to learn at first, that I had to bear away to depower and I have found it is much faster to bear way and use the extra speed from a puff than to release the spinnaker which instantly kills you speed.

With a crew I work the traveler and he trims the spin downwind, it is alot easier and more fun to be honest, the two of you just have to be in sync to get good speed out of the boat.
