One of the Bobcats that was for sale was listed with a 2hp outboard -- that sounds a lot more practical than trying to row a boat that wide and with that much windage.
Alternately you could go with a two-battery trolling motor setup, which should get you back home rather slowly as long as you don't go more than a few miles from the dock. Cost might be close to that of an outboard, depending on what you have already.
My experience with sailboats is that they don't row worth a damn -- only good in places with no wind and for short distances, or where motors are not allowed. Otherwise just get a stainless steel adjustable motormount and carry the outboard.
