"I was hoping to run the outhaul on my C250 centerboard (1996) out the mast end of the boom and back to a cockpit clutch. The line enters the boom from the clew as a wire and exits the other end as a line. Anyone want to give me a 'clew' what happens inside. I can always take it apart but I thought I'd try this first."
It gains mechanical advantage within the boom. All that is necessary to running the outhaul to the cockpit is to remove the line from the exit port on the side of the boom and turn it down to route aft... rather than back along the boom.
Actually, the outhaul line coming from the tack end of the boom is too short to make it back to the cockpit. So, to replace it I need to know what to expect to find inside the boom, or if there is an easy way to access the end inside the boom.
If you just need to replace the old line for a longer one, try attaching the new line to the old one and then simply pull it through the boom.
When attaching the two lines, butt the ends to each other then either sew or tape them together. Make sure that the joint is somewhat flexible and not too bulky so it can make it through any blocks.
Catalina didn't provide a diagram in the manual to picture the internal routing. I don't know what purchase multiplier is within the boom... but I suspect that its something like pictured in the drawing, probably a three part because there is a fixed block within evident by the thru pin on the boom.
If wanting to make up solid line long enough to lead aft, the boom will have to be taken apart. I'm thinking that its likely that the aft end would be the one to remove. Drawing it out will bring the floating block with it... to the point of reaching the becket that the line is bent on.
Keep in mind... that this is all a guess based on the pin thru the boom.
Oops! <img src=icon_smile_blush.gif border=0 align=middle> ...I forgot that the outhaul might be a two part system, which means that what I posted earlier will not work.
In the future I'll contain my comments to things I actually know something about, which in my case is very little.
OK, I bit the bullet and took the aft end of the boom off to find out what was needed to replace the outhaul line. The diagam previously shown was close to what I found. Mine did not have a pully around the pin (located about 3 feet forward of the aft end of the boom.) The end of the outhaul line starts with a bowline around this pin, heads aft and around the pully tied to the wire outhaul, and then heads forward and out of the forward end of the boom, (2 to 1 purchase.) It was easy to replace the line. I pulled the pin and using the old line, pulled a new one through the boom. I then fed the aft end through the outhaul pully, made a new bowline on the end, and then fed the loop back to the location of the pin by taping the loop to the end of a broom handle. Once lined up, I replaced the pin and then the end fitting on the boom.
Thanks Ken, I will revise the drawing and make it available so others can see what the deal is.... I knew I ought to go out to the boat to see where the pin was... but thought it was worth a stab.
