Agree with HighSeas... Years ago, due to poor/contaminated fuel
, more than once had to "tow" my Irwin
(14+ ton) back with an inflatable
(8hp Eska). Don't think I'd like to run an inlet that way, but worked just fine on a river...
Strap it along side so the outboard
is about at the aft waterline/rudder, set the outboard
so the sailboat rudder
is more or less neutral and steer with the boat rudder
until time to dock
-- when the steerable prop is pretty handy...
