Trying to expand my knowledge......I was over at a marina yesterday evening just as an MTI was being placed in the water with a fork lift. The lift drove away and I noticed it had what looked like a cradle from a trailer on the arms with the cradle being made by Myco. Do the cradles discconect from the trailers for this, or would the marina just have one onsite to drop catamarans in the water?

I know Myco makes cradles for boat lifts, so I'd have to guess the cat sits on this cradle you saw. I'm sure a fork lift could pick it up with boat still on it (I would think you could make spots for forks to slip in/connect pretty easy). With enough $$$ anything can be done

My guess is the boat either stays on the cradle or it does detach from the trailer. You do not want to pick a cat up other than by the running chines that it sits on on the trailer. So unless they slung it off a trailer with a crane you couldn't get the forks under those chines.

Jaguar was doing that long long ago , it becomes a shop cradle .

That makes sense. Thinking about it more, it seems like it would be a huge pain to unbolt from the trailer each time the boat goes on/off the trailer then line everything up to place it back on the trailer chassis.
