We tow our Trinka 10 behind us unless we are really heading offshore. Then we leave it at home and pack our little AquaDutch fold up inflatable along. The Trinka happily rides along behind us bailing any water that finds its way in through its Elvstrom bailer. It has never given us any cause for concern at all. As for the motor I simply lift it from the dinghy to the storage bracket with my arm. it is only about 40 lbs though.
