What are the sails? If they are 'racing' sails, chances are you would never use them for cruising. Are they dacron or composites? Composites are a pain for cruising since you have to be extra careful with them (flogging, careful folding). I would look very carefully at maintenance and overall quality. Note that a newer engine with worse upkeep is 'older' than an original engine that has had proper care. Also, are the hours on the racing boat mainly just getting in and out of harbour? This can be very hard on the engine since it may not reach proper operating temperature each time.
In South Africa doing lots of boat stuff. Departure north from Cape Town around December 15th. Arrival in the Caribbean around the beginning of February, after 5300 miles or so.
