Lifting a DSI from a hoist

I have access to our Yacht Clubs hoist. I like the idea of using this to launch my DSI as it will keep the trailer out of the salt water and the hoist is FREE. I have used this hoist for years when I had my Cal 22. I found this type of launch facility quite simple to use.
I was thinking of building a bridle that would attach at four points; the port/starboard shrouds and the port/starboard stern cleats. These points seem pretty strong. The total weight would be the hull itself, the stepped mast and floorboards. To reduce weight, I was planning on keeping the rest of the equipment out of the boat until it boat was in the water.
Anyone have experience with this type of launching?
Thanks
