I probably will use the existing crane. Sea-Doo's are a lot heavier than 500 pounds. The entry level one is over 750!
The dinghy I'm looking at will likely be around 900 pounds all said and done (boat, motor, gas, battery, etc). but due to it's width it will sit further back on the platform (hanging off actually). so I'm wondering if anybody has any experience with carrying a dinghy on this model boat.
