To do bottom maintenance on my CS 17, I launch it at the beach in about a foot of water. Then, tip her over with a little weight on the masts. I then can patch dings on the keel and Centerboard, and spend a nice afternoon sitting on the sand waiting for the epoxy to harden. A case of beer, radio with a ballgame on, a sandwich or two, some good company, and we've got a great day on the water. By evening, sail back to the launch with a smile and sunburn on my face.
I do have a boat lift from Brownell as well for off season work. It was pricey, but I use it a few times a year to maintain the "fleet".
