Greetings, Paul.
Ours was a
new boat, heavy,
single left hand screw, no thrusters, big
rudder. My wife and I did just what you would do
learning to drive a car -- we went to a quiet area (bay with little traffic) and practiced.We approached channel markers, "docked" beside them, hovered in place, backed, made tight turns, learned the effect of
wind and
current, got a feel for the effect of throttle and
gear shift, and all that. Then for awhile we warned
marinas as to our situation and
experience, so they supplied line help and didn't put us in slips that were very difficult for our
boat, independent of
experience. Ditto on locks. It helps to talk with the person on the
dock, not the secretary in the office, and to caution against things like grabbing a bow line and pulling, which with our round bow pivots the stern in the other direction, messing up the entire approach. We found
dock folks to be very helpful when asked; after all, they don't want you to crash, either.
