I have sold plenty of used spinnaker kits. Don't ask me for a price as I sold almost all and only have one old snuffer now. A used setup will be about $400 spinnaker, $300 for snuffer, another $100 for rigging, $150 for the pole, and $100 for bridles and mounting. I think this is a conservative number, so...you are looking at about $1000 to mount anything like this on a P18-2. If your boat cost a couple of thousand, then maybe for a joy ride it is worth it. If it is any more I would encourage you to find a used F18 which is already designed to take such stresses. We have some used Tigers on the West Coast for $8000 or less. A used Nacra I-18 or F-18(second generation) is even less.

I do not know about shipping to Chile but unless there are P-18-2s down there to buy I think you should reconsider what you are looking for.
