Dan,
I have had a 35 fountain on an Airdock for 6 years... IT IS FABULOUS!!

you will need the model size D/E, which covers both the weight and lenght of your boat. There was one for sale in the OSO classifieds recently.

you can't beat Air Dock for Price (at least half of any other), simplicity (requires only 2 psi to lift your boat), and leaving a very small foot print... slightly more than your boat takes up. It's hard to even see when your boat's on it, and you can raise it high enough to get everything out of the water.
