If towing the
dinghy with the motor on it is required because you have no decent place to store the outboard on your boat, then lash the motor to the floor of the
dinghy. This keeps the bow down, eliminates the extra drag of the motor itself, and lowers the center of gravity to discourage flipping over.
We never tow the
dinghy with the motor on, but it's easy to lift our 2hp up onto the stern pulpit. Our inflatable flipped on us once in 25 knots of breeze, and promptly suctioned itself to the sea and stopped. Our 40 foot sloop kept on going and ripped the towing eye clean off the bow of the
dinghy. Since then we tow it close in without the motor or anything else that isn't lashed down.
