19jib39 and Stu, These are many of the changes and add-on I did on my 1980 C22.
1. The very first and probably the most important item was to buy a Loos Tension gauge and tune the rigging. The wire tensions are 10% of the breaking load and is easy to find these numbers or I can help later. Tune the first time, sail her hard a couple of times and re-tune. Then tune yearly or when there is a noticeble slackness in the shrouds. I have 4 foot PVC 1" tubing with caps slid over the shrouds to protect the sails.
2. Run lines aft to cockpit or at least to the cabin top rear. Sheets and halyards. Downhaul, Cunningham, outhaul and topping lift.
3. I had the standard equipment 2 foot jib sheet tract and sheeves. I added an additional 4 foot tract to the inside of the OEM tract' overlapping 1 foot and the remaining 3 feet was in front of it. I had 4 tract cars.
4. I had hank-on sails, they were a 110% jib in good condition, a new Ulman 150% jenny and a new Ulman loose footed, full battened main and a 170% drifter. All sails must have multipule telltails. The main too.
The toppinglift, cunninghan, downhaul and outhaul all had stoppers or line locks mounted on the cabin roof rear. The down haul was just to drop the jib or jenny when the wind was so high that the sail was pinned to the forestay. Secondly, the topping lift is a life saver. If I got in trouble with big wind, very rough seas or both I could simply pull the topping lift line and it raised the boom by at least 1 foot above level. Now I would lock the tiller straight ahead and drop the headsail with the downhaul. It also allowed reefing the main if needed. The boat would do lazy, fairly tight circles and drift downwind while doing this. I could work without worrying about the boat. I know all about heaving too and have done it many times in other boats (over 23 feet), yet this is the fastest way to stablize and work on the boat. Try it and you will be surprised. I teach this trick to all the new sailors I teach to sail. This is one of the very first lessons so they can stop when they are over their heads and scared. A fast bit of safety while regrouping.
The loose footed main is the best sail I ever bought but MUST be flown with a good hand on the outhaul.
Next, mark the mid point of each headsail on the luff, hoist the sail and stand back with the boat on the trailer or where-ever and draw a line in your head from this midpoint down through the clew and continue straight to the jib car tract. This is exactly where the jib car sheeve should be as a starting point when using a headsail. I actually used string to do this. All adjustments start from here.
Go buy a very good book on sail trim. The best books I fould were "Mainsail trimming" by Felix Marks. He also has one on headsails but that copy is on the boat so I can't give the exact name. These are VERY GOOD trimming guides.
I sail solo 98% of the time so an inflatable vest and a 6 foot lanyard are mandatory. I also trail a 50 foot line if it is ugly out there.
Enough for now. More later if needed.
Stu, we slept in the cockpit or in a tent on the shoreline. Also, C25's and most times C27's are fish bait for a good C22.
