I think it's going to be similar to any sail boat. It really depends on the age of the boat too, but here are the things that I would check:
- Check running rigging.
- Check the hull for any distortions, cracks, welds, etc. If there are scratches and slight gouges that would be normal wear and tear.
- If tramps are included check for dry rot.
- Check the sail for condition.
- Check that the drives are in good working order.
- Check that the akas aren't bent/creased/nicked.
- Check all bungees for elasticity
- Take it for a test sail...
- Check that the hatches don't leak.
- Look inside the boat for any leaks after the sail.
- It should include everything that was delivered with the boat initially...
- 2 vantage seats or seat pads (depending on the year)
- 2 mirage drives
- 2 cassette plugs
- 2 paddles
- paddle "T" handles
- aka carry bag
- through hull fittings (depending on the year)
- 1 gear bucket with dividers
- rudder bungee
- sail cover
- some extra shear bolts and at least 1 extra rudder pin
- an owner's manual is nice, but you can always download the PDF
- If it's on a trailer and it's included check the condition of the wheels/tires, suspension, cradles/bunks, wiring, etc.
I'm sure I'm missing something, but it's at least a start. Good luck with the purchase!
