Good day crew!I recently partnered into a Spirit 28, that was unrigged: the mast was down, sheets and halyards bundled together, and several buckets of line, blocks, and various bits and pieces. I'm the mechanically inclined partner, so it falls to me to reassemble things. I've spent several weekends trying to put this puzzle together.My partner and I have been able to sail using the main and stay sails, but I'm having a little trouble figuring out the Genoa:The forestay (stainless steel cable) is sleeved with a white plastic sleeve that extends from near the deck to near the masthead. Said sleeve has a channel into which the front edge of the genoa dresses as it is hauled up, thus the front edge of the genoa is attached to the forestay for the extent of the sleeve.My partner believes that the sleeve is part of a roller furling or reefing system. I plainly do not know. There is no evidence of a drum or anything like it, but it's possible that some parts were lost or stolen.My knowledge of sailing is limited. Does this sound like a rolling system, or just another way to fasten a sail to the forestay?Just one more question: Can someone recommend a site or book from which I can learn some sailing terms and concepts (luff, leech, reach, jib, jibe, and so on and so on)?Thanks thanks thanks in advance for helping.Drake.
