I'm thinking of adding a simple outhaul to my boom. My thought wav to attatch a small block through the clew of my main and one to the end of my boom and add a cleat to the end of the boom. I'd tie a bowline into the clew and pass the line through the block at the end of the boom then back through the block at the end of the clew so I could pull the line aft and cleat it off. Does this sound correct? Any tips on mounting the cleat to the boom. Can I just use self tapping sheet metal screws?

I have not used it yet as I am not yet in the water, but I installed something similar to:

from bits and pieces I had around.

Keven, I am no expert by a long shot but last year I did exactly what you have in mind but I used a closed clam cleat. Unless you have a loose footed main, Don't expect the out hall to do very much. I can see where this is very functional on a loose footed main but with the bolt rope the foot of the sail doesn't move that much. I was a little disappointed.

I simply used an old mainsheet rig, attached with D-shackles to the clew and the aft end of the boom. It's gives a 3:1 or 4:1 mechanical advantage, and I always haul it in underway with the boom centered, pulling the line forward on the port side and aft on the starboard side, for more power with both hands (4:1 advantage this way), and then re-cleating with the cam cleat. This rig was left by the PO on the boat along with a new mainsheet setup.

I have a loose-footed main, so it makes a noticeable differnce when I release the outhaul to add curvature and power to the foot of the main if sailing on a beam reach. Similarly, when hauling it in, the foot of the main is flattened completely for beating to windward.

I later cut off the extra tail of the line.

Some C-25 sailors prefer leading the outhaul to the mast and back to the cockpit. Too complicated for me!

I added a cleat in the slot on the top of end of the boom, like the cleats on the cunningham on the mast. Outhaul Rope goes to the cleat, back to the sail and to the cleat.
Works OK, but then I'm just a little ol lake sailor. No blocks.

I had blocks but it was just a little overkill for me.

We will install a 5:1 internal outhaul this summer. The line will exit forward, down the mast to a turning block, through a deck organizer and back to the cockpit.

Mine is similar to John P's but with a simple "V" jam cleat

I bought [url="http://www.catalinadirect.com/index.cfm?fuseaction=product.display&product_ID=594&ParentCat=40"]Catalina Direct's 8:1 internal outhaul[/url] for my loose footed main and while I like it I also wonder if the external might have been a better choice because of ease of maintenance and (I'm assuming)larger blocks.

I installed an 8:1 internal out-haul on Zingara many years ago and wouldn't be with out it, especially if you race, but even if you don't it will improve your sail shape and performance.
Islander - Your disapointment might be due to the cut of your mainsail. Mine not loose footed but is full cut with a very large shelf, and that's where the outhaul (and to some extent, the cunningham) make a very noticable difference.

I can't wait to get out and actually use mine (8:1 internal). The first thing I noticed after installing it is that the 8:1 turns in to 1:8 when giving line and I'm wondering how easy the wind will allow the sheet to be pulled out with my loose footed main.

Dave, I have a 4:1 external outhaul on Confetti's loosefooted TR main. A lot depends on the friction in the Clew slide as to how easy it goes in or out under load. Mine is a coated slide, but thru the years the coating has worn away a bit. I simply ease the main (or vang if downwind) for a second while the outhaul is tensioned or eased, and then trim back in.

Even if the hardware says internal, if you are concerned, why not just set it up externally?

Here's what I set up. The orange line is the topping lift. The outhaul line runs forward to a cleat on the port side of the boom.

block, block, cleat The big purchase outhauls would be nice with a bolt rope foot but with a loose foot there is no need for much purchase. You can see by the foot of my main that I had over tightened it with my minimal purchase. In fact I think people with loose foot mains should install stoppers in the boom slot to keep the clew slug from being pulled back to far.

Interesting, I would have thought that more purchase would be needed with a loose footed main. The stopper knot is a good idea. Just release for downwind sailing.

There is no friction from the foot bolt rope with a loose footed main and the metal clew slug moves with minimal friction.

we use a 4:1 external block system on our loose footed main going to a jam cleat on the boom...it is a challenge to adjust in strong conditions when the boom is outboard the cockpit...would be better to run back to the mast and into the cockpit...

Jerry,

I agree!! However, the more turns thru blocks/fairleads the line makes the more friction. For our outhaul, I have the cleat on the boom where it is convenient to access and use when sitting on the cabin top (its just aft of the boom vang bail on the mast. Sitting there you can pull it tight, or ease it and are able to grab the foot of the sail to pull it back in when loosening if you need to.

I built an 8:1 internal outhaul with cascading blocks to minimize cost and friction. I have a sliding gooseneck, so outhaul tail goes to head knocker pivoting cam cleat hanging mid boom. Has been in use since 2002 without maintenance or problems.
