westerbreaks are good motors and so are the yanmars, but i would consider a sail drive a down side due to issues they have. just for your knowledge a basic main sail for a 27 foot boat is under a thousand. if you are handy you an do a do it your self standing
rigging job for about a 100 per wire on a 27 foot boat ( assuming the
turnbuckles are in good shape ), most boats will have 8 wires for standing
rigging.
