Laser lift?

I did a couple searches, but didnt find anything, so sorry if this topic is already covered somewhere.

I am looking for a boat lift so I can store my boat in the water. I'm often up to the lakes by myself, and a dolly is fine, but the ramp is halfway across the lake from my place. I want to be up and sailing in 10 mins, so I thought having some sort of lift/dry dock/whatever would be a good way to get the boat in and out of the water fast.

Anyone have thoughts on such?
