Thanks for the suggestion of an electric-powered trailer dolly. It may
be just the ticket for one man to move a 2,500-lb boat.

I am just hoping that a man-powered version is good enough to move my
boat for a short distance -- like moving the boat 5 feet horizontally
to the side of the driveway. Because of the fact that you have been
using your man-powered trailer dolly to move your 1,800-lb boat, I
would like to know whether you think that man-powered trailer dolly is
good enough for moving a boat in such a short distance. Thanks in
advance for any info.
