Yes, there are alternatives but...
...whether they make sense to you depends on where you want to do your sailing. E.g. boats are cheaper (in an oranges vs. apples sense) in NZ and OZ, also in S Africa and for that matter, Canada. But since you state you only plan to sail/cruise 3-6 mos/yr, you'd best find a boat in a world region that strikes your fancy.In general, buying a boat in Europe (Baltic to the Med) is more expensive because most owners have had to pay a Value Added Tax at the time of purchase and most of that cost is passed on to each successive owner. They may also include systems (heating, smaller sail plans up north) or be built in ways fashionable to the area (e.g. teak decks abound in the Baltic boats) which you'd find incompatible with your cruising plans and/or tastes. Inevitably, Euro boats will have systems specific to their locale and which may require refit once you leave metric-oriented or Euro-based supply centers. Boats in the Caribbean can be abused, former charter boats and/or in locations from which they might need to be moved for major work to be done...but places like St. Thomas and Chag Bay in Trinidad offer used boats in sufficient concentration and with abundant yachtie infrastruce to make shopping at least fun and potentially cheaper (tho' not by a lot).There are other spots from which I've seen great buys occur (Singapore, Hong Kong, Rio Dulce in Guatemala, Panama) but, just as in the U.S., these seemed to be more specific to the circumstances of the individual owner than due to the geographic location.Jack
