Idea to improve boat lifts

Hello fellow sailors, for my Engineering project im working on creating a boat life designed specifically for catamarans and wanted to get some inpout from the people who use them. If you could take this extremely short google survey I would really appreciate your help: https://docs.google.com/spreadsheet/viewform?formkey=dENzNjZ2T281dnY4OG9BMFR6cHgzZVE6MQ#gid=0
I'm having an issue trying to set up a lift and am looking at alternatives. I have just purchased a used Air-Dock model B and am trying to design/engineer/rig a modification to make it work for my application. Their model for a cat was about $4,600, new. Mine, used was $1200.
What are you working on?
I am looking at everything before I start to assembling the frame for it next spring.
Nacra 5.7...19' 400 pounds. I have a floating dock in a marina and can not use the bottom of the marina.
Good luck.

Capacity is not an issue; hull compatibility is.

Yea, that was weird. The guy registered and then posted three kind of boilerplate messages in different threads. No links or anything but I figure he was testing the system to see what he could post.

Might have been innocent, but I'm kind of ruthless these days because of all the time I spend keeping the site free of nonsense.
