When we chartered a big huge catamaran in the islands, it had blocks at the clew & luff (single line system). I cannot recall off the top of my head how they were "attached" to the sail, but instead of cringles or pressed rings, the blocks may have been sewn directly to the sail with webbing. Still a lot of flogging hardware on a smaller boat though..I'd worry about getting beaned in the head..You needed a ladder to reach the boom on this cat..no chance of getting whacked with a flailing block.
my 1977 boat (and 1977 sail when I still had it) had a cunningham cringle AND the boom gooseneck on the track.
- The P.O. pinned the gooseneck with a bolt (which is just fine with me..no crashing boom!), so the track is no longer being used. Looking at the style of reinforcement patches on your sail, it looks similar (i.e. stock Catalina/Odyssey issue sail.) My new sail doesn't have a cunningham ring (I never rigged the old one), but since it is a cruising boat, I pretend I don't see that the luff needs tension adjustment, or if it is bad enough, I just go adjust the halyard at the mast. For reefing, Quantum built in a little 'hand hold' into the web ring, so I can pull down with one hand and hook the ring over the reef hook with the other. Tighten the halyard back up, pull in the clew line & done!..again, since my halyard is at the mast, & my reef line is on the boom (similar location to those cleats on your boom) all this work is done there.
Um..I am trying to think where I got my tack hook..I had one of those big curly Q type ones on there that I replaced with something less obnoxious after it broke..mine is a pretty simple set up & simply bolted to the gooseneck. I'll see if I can find an example...try searching for "reefing hook" at Defender...they have a few different ideas.
For your setup..I like Joe's idea too..you must have foot tension (& luff tension via the halyard once tack is secured) to have any decent (flat) sail shape. Reefing into a big sloppy, baggy mess almost defeats the purpose. Having some way to pull the tack for the reef forward (i.e. down to the mast) and doing the same at the clew by moving the block aft should help immensely.
Making these modifications & testing them at the dock on a sunny 75 degree day with no wind is also a good idea. Trying to figure it out when heeling 30 degrees in a cold wet 25 knots sucks.
Edit - OK, looking at your set up again...you could simply take the current 'dead-end' at the cunningham and move it down to the tack ring/cringleor some other solid piece of the gooseneck. Problem #1 solved.
2nd problem: For fun (i.e. at the dock) you could relocate the current 'tack blocks' to the mast cleats..i.e., use the cleat as a padeye. This should allow you to get enough forward tension on the tack ring for the reef. If this proves to work, a permanent pad-eye could be added on each side of the mast for each block, (low enough to allow for the space the block takes up & still get the tack ring down enough) or you could simply continue to use the cleat(s) as a pad-eye and lash with something small & strong like spectra. I'd try something easy like a sail tie for the experiment.
So..now I need some help figuring out how the lines run..if you have a dead-end at the clew(on the block pad-eye thing) and a dead-end at the tack, do you have two separate lines for each reef (i.e. total of 4?) Maybe three since you seem to dead-end the luff reef lines in the middle at the cunningham. Damn, I am confusing myself now..
I have some ideas, but I need more pics, or a diagram or something.
