I am 90 percent finished putting the spinnaker on my 5.2. Things to look out for or that I have done. I purchased a Hobie 16 spin new from (well he knows who he is, thanks). The 5.2 mast is 27' tall but you do not want to hoist the spin from the top as it is unsupported. I measured the distance from the point that the shrouds connect to the mast to the top and divided it in thirds. I then measured up one third from the shroud attachment point and that is where I attached the turning block to hoist from. I built a carbon pole but don't have the lenght in front of me, I think just over 11'. The Hobie 16 spin has a luff length of 21' 5" and fits perfect with a few inches of flex room for mast rake variations. I am building mid pole spin hoop snuffers and bags which will be marketed soon. They will be availble in fiberglass or any combination of composite materials ( a cheap plug for my work)<img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />. Top half of the snuffer that is finished.

My tack line and bow attachment lines run through the pole and exit straight out through an end plug I made. Also the attachment point of the pole to the front beam I built oot of stainless and a HDPE plug. I can take some photos of the spin setup if you 5.2 guys are interested, my explanitions are not that great, A writer I am not. I think the Hobie 16 spin will be just the right size as I sail single up and love heavy air.
