I have recently acquired my Hunter 37C (S/N: HUN37174M80G) and had to remove and strip my main boom prior to having it painted. I would appreciate another 37C owner telling me what should be rigged through the boom. The aft fitting obviously takes the topping lift but there are 3 other lines that run through it. One has to be the outhaul (with internal wire and block). One possibly for the lazy jacks. What are the others for? I guess a photo would be worth a thousand words. My boom is sheeted in the cockpit. Has anyone converted theirs to mid-boom sheeting? I would like to convert mine and I believe later 37C's did have this. I'm new to Hunters but I know there is a wealth of good-hearted owners out there that will put me on the right track (or tack, whatever). Thanks from Dave

I don't own your boat, but I can say that Lazy Jacks are not internal in your boom, but external. You probably have an outhaul and two reef lines.
My 1980 H36 has a Kenyon mast/boom. I believe same for the 37.
The other two end-boom sheeves are most certainly for the 1st and 2nd reefing lines. On mine, they lead straight through to the gooseneck without any internal block system.
You might want to check out Ed Schenck's many excellent posts on his mast and boom and traveller refits to his 37. His last posts a few months ago were about installing a new traveller. He elected to maintain the cockpit sheeting (just aft of the companionway.

I am also looking for the same info. I painted my booms last year and I did not strip them, so by the time I got to them, I had a pile of lines and blocks on the ground. Now, its like a puzzle. If I recall, there are blocks inside the booms that are secured by the bolts than pass through the boom. I just cant remember how.

Rardi, I appreciate that information. I just need to figure out the routing through the 2 sets of reef points.
Dave:
At the boom end, the reefing line rigging is quite standard. You should be able to find all sorts of diagrams on-line for the routing of the lines from the boom end sheeves to the reefing clew points and tie-off on the boom. I am assuming that your boat does not have the system that can take care of both the clew and the tack at the same time. Then things get a lot more complicated. At the gooseneck end, I have modified my stock reefing line routing to be different from the stock set-up. So better another forum member answer!

I thought there was an internal view of our Kenyon booms on Rig-Rite. Could not find it just now. But there is an internal set of blocks for the outhaul. The two reefing lines I have never had to pull through, always had a messenger line which was the original line or the next upgrade. Have new ones this year in fact. From the gooseneck they lead over a sheave under a cam cleat. Then through the hole to the aft end and out over a sheave. Then up through a reef point and back down to tie to the boom, starboard on lower and port on upper reef point on my boat. All my lines are still at the mast hanging on additional cleats that I installed there.
Here is some not very useful info: http://www.rigrite.com/Spars/Kenyon_Spars/5072-boom.html#5072 Standard Outhaul

Outhaul blocks can also be mounted externally. Example within this url link.

Upon purchase of my boat, the outhaul was just a straight line exiting the gooseneck and pulled back 180 degrees and tied off on a cleat mounted on the underside of the boom. Rather than try to internalize an outhaul block purchase arrangement, I did as per the url diagram ... except reversed and placed up at the forward end of the boom instead of from the end. Frankly, I find that the outhaul for me is a set and forget sail adjustment. I just leave moderately snug all the time. When the sail is up and there is weight/friction on all the boom slugs, the sail foot tension can't really be increased decreased anyway without first raising the boom with the topping lift. Since my topping lift adjusts at the boom end rather than being a rope line run through a masthead sheeve and eventually back to the cockpit, raising the boom while under sail isn't practical for me.
