I own a 320 and was wondering if anyone uses the Dinghy Ramp Davit system on their swim platform. I am now using the Weaver Davits. They work well but it is a pain to always take the motor off. I also do not have a fuzzy feeling about placing the motor in the boat. I do not put the motor in the compartments for fear of a gas vapor issue but even the fact that it can topple over in the cockpit on the way back to port and hurt someone scares me. They are expensive but I use the Mercury 270 Airdeck almost every weekend.
