Remember this point is only doing a 90° turn so the mounting load is 1:1 with respect to the load on the line. I’d say you might get 75 lbs per screw on it. I’d rivet but that’s me. Also there’s no reason to assume sheet metal screws. I’ve pulled boom end caps to mount eye straps on other booms.
The mainsheet pictured is a little undersize being only 5:1 running down at a 45° might get you 5.5:1 but the factory was 6:1 and I’ve run 6:1 / 12:1 combo for racing. http://www.catalina27.org/images/C27-96DPI21.jpg Racing - because 12:1 was faster than winching.

The image I am referring to is: http://www.delanges.com/Catalina_27/images/Traveler_2.JPG Its from Steve’s website and shows his mid boom traveler. My rig will be slightly different, with double ended sheeting. The folks at Catalina Direct suggested I run the sheet from the edge of the cabin top (near the handrail) forward to a spinnaker block on a spring then at a 45° to the first blocks on the boom and so on. In the image above, while just single sided, he runs his sheet to the mast then down through a turning block then to a deck organizer then to the cleet. My question to Steve was, it appears the block closest to the mast is held in position by a small stainless strap with just 2 sheet metal screws instead of a full through bolted bail on the boom, is this strong enough?

Running the mainsheet across this same area then makes sense, plus eliminating one block from the whole setup. I think you can see what I mean from pictures on my out-of-date website: mywebpages.comcast.net/sailrmann Bob Mann Windcatcher '85 #5928 -------------- Original message -------------- From: "Joe McCary" <[EMAIL PROTECTED]> Actually, I was interested in the strain on the block on the boom closest to the mast. It looks like that is held on by a small stainless strap and 2 sheet metal screws. I was wondering if that is the case and how much pressure is on that block. I like the idea of running the sheets down next to the mast (mine were set to go out from the boom at a 45° angle toward the shrouds making that area impassable. You have opened up that area by running the sheet back to the mast and straight down and into a deck organizer then to the cleet.

Your website offered some insight as to placement of the parts. I have one question, I noticed you have what I guess is the main sheet running back to the mast then down to the deck (I thought this is a good idea) but it looks like the last block next to the mast is only held in place by a small bracket, not a full bail like the others. What pressure is on that block? Mine will be slightly different, I have a double ended system, the sheet will end on both ends so you can adjust from either side while sailing. That means I need 2 blocks coming down to the deck, not a single like you have.
