Tough call. Both are good boats.
The 25' Mac is bigger, light and quick (recently apparently entered into the "sailboat hall of fame or some such...) It can be singlehanded, and
parts seem readily available. Light and fast when properly sailed, no frills. Does it have the pop top
canvas? Motors (and especially ones capable of
charging batteries or running lights) are expensive.
The 22' has an
outboard, and they're not
cheap. They both have trailers (condition?) and sounds like they may both have
hull and
rigging to be replaced. Check your agent for
insurance costs. They are generally pretty
cheap.
WHERE ARE YOU GOING TO STORE IT?
