If you get into some high wind,
the dinghy might pass you. Ours did once (motor attached) and it ripped out the bow ring on the dinghy. She turned upside down, got water in the fuel, and lost the oars. It was a b**** to recover. Then things started to get really bad when the inboard diesel quit. No dinghy power to tow us into the marina, no oars, high winds and sick passengers. I still tow the dinghy but I usually put the motor on the stern rail of the main boat. Think about it is all I can say.Things to consider:1. How heavy is the motor?2. What is the weather expected to do?3. How is the painter secured?4. Do you have a backup line attached?5. How fast do you want to go?6. How far are you going?7. Is everything on the dinghy well secured?8. Can you catch the dinghy if it gets away?9. Can you do without the dinghy?10. Do you embarass easily?11. Do you have insurance to cover the loss?12. Etc. etc. etc.
