Another option that works is to tie front of dinghy
to front of boat being towed. Tow with dinghy
in reverse. This gives good directional control. I heard about this from Lin and Larry Pardee at one of their seminars. I tried it on my 42 foot sloop
pulling with 15 HP dinghy engine
. No one had to steer the big boat.
If Boat to be towed has stern compatible to being pushed by rib
type dingy, that will work like a charm. Person steer sail boat as normal, person in dingy keeps dinghy square to stern and adjusts throttle for speed control. Also attach a line in case you need some reverse from dinghy to slow or stop vessel.
