I'm currently upgrading from a Prindle 18C (see classifieds) to a P19 (non-MX).
The two upgrades I want to do to the 19 to make it more competitive (my wife is tired of losing <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" /> )
is MX it and add a spinnaker. MX'ing a 19 is well documented so no problem there.

What I can't find is any information on how to and what equipment is needed to add a spinnaker setup.

Anyone got any info, hints, tips or hardware recommendations?
