6.5 hp diesel? What make?

kubota? Yannmar? Lombardini? I'm surprised that 6.5 could push
anything of that size. other than a small riding mower.

You'd be surprised. Sailboat hulls, especially a racing sailboat that
is well maintained, have very slippery hulls. In flat water, no wind
and no current it takes almost nothing to get tthem moving. I was
once out cruising and racing on a 40 footer that lost its prop. We
lashed a dinghy along side like a tugboat and used its little 2 hp
Evinrude to bring the big boat into the dock.
