I tried it out in nice, light conditions, reefing the sail and shaking out the reef several times. It works smoothly and  produces a reasonable sail shape. I wish I could have figured out a way to mount the tack reef line even further forward,  as it pulls straight down, but I could not. The foot of the Sun Cat sail has a bolt rope, so adjustability of the shape of the sail is somewhat limited by being attached  to the boom, but outhaul tension does make a difference in performance. The problem is, it doesn't make enough of a  difference to make me get up there and untie the outhaul, adjust it, and retie it. Also, running the outhaul straight to the  hole in the fitting on the end of the boom will chafe the line. My solution was to add a small block on the end of the boom and yet another SeaDog Clamcleat. Now it is easy to reach up  and adjust it then jam it back in place, and chafe on the line should be reduced quite a bit. I got the metal ones because jam cleats wear out, and I figure these will wear out more slowly. Even when new, they are  not a very reliable attachment. The line can slip or be knocked free, and if jammed under a heavy load can be difficult to  detach. I'm using them on this boat because they are small enough to fit on my small boom and they are cheap, quick, and  easy to use. Installing the same kinds of modifications on a larger boat, I would use cam cleats or conventional cleats. Whether using moving cams with teeth or jamming in a wedge, cleats that stop a line by pinching down on it are harder  on the line than good old fashioned cleats. I'm willing to replace running rigging or swap it end-for-end more frequently for  the convenience of jam cleats on the Sun Cat, which is why my boom now has four of them. I visited Tom's Blog on the Sun Cat changes and copied his downhaul system. First Mate now likes the way the sail comes  down. The sail and gaff are not heavy enough and the sail too stiff to drop the sail. Now I just release the halyard and use  the downhaul and the gaff halyard to control the decent into the lazyjacks. I did make a few adjustments to his design. I  used the same 3/16 line and attached to the the end of the gaff gooseneck with a knot. I added the same type of stand-up  block to the base of the mast stub where the other halyard blocks are. I ran the line through the left section of the deck  organizer. There is no sheave there and it runs against the frame of the organizer but there is no load so it should be ok. I  installed a very small bullseye fairlead between the cabin slide and the spinlocks there is a opening there in the edge of  the deck with screws. I sized the line and added a stopper ball to the end so that when the sail is fully up the ball is a few  inches from the fairlead. Thanks Tom for getting me started on this, I had all the parts in my spares bag and only needed  the line and stopper ball.
