I have a 10' alum bottom hypalon inflatable which is towed, but the rather heavy 8hp 4 stroke
motor is always removed and stowed on the rail. I use a demountable (inexpensive well made) Garhauer lifting crane which I can do alone. The engine
has a bridle on it for that purpose.
The dink is towed using 2 rings which are attacked to the hypalon. A bridle of dacron webbing is attached to a long 3/8" pair of lines each attached to a stern cleat. Finally the dink has an aluminum
tube welded to the aluminum
at the bow. A 1/2" line which is the working dinghy
pendant... (we don't use the bridle for tie up) provide a 3rd line. These 3 lines are long enough such that the dinghy
tow distance c an be set to the best wave pattern as we make way. The dink location can be perfectly "trimmed" for the least drag.
I don't know I would do this in large waves such as offshore
, but for all coastal conditions we have encountered this has worked. Of course in large following and quartering seas the dinghy does get moved a lot by the waves which may be traveling faster than the boat. This is the only time towing has been worrying.
