My 40 has a 1 1/4 inch, t track mounted on the side of the boom with a Schaefer Jiffy reef slide/bail that slides up and down the track so you can position the clew attachment point for multiple mainsail reef points. The reefing line goes through a hook that you use to select which reefing cringle you want to use.

I think that more or less says this is still how it is done. Our own ancient Frers 33 also tied around a painted boom. No wear on paint on the two C&Cs and the wear I see on the Frers boom is not from the reef line. Mike Persistence 1987 Frers 33 Halifax, NS In the water since Monday!

I also considered having a single piece of rod drilled and tapped at the correct distance for my selected pad eye fitting. I'm just kinda trying to figure out what others do. Everybody else just tie it to the boom? Thanks for the idea, lets keep 'em coming.

Some sort of lightning arrest system was my first guess, but I thought it was odd that the mast wasn't connected to it... Which would be essential for a lightning system. I hadn't considered an old short wave or Loran setup. I'm going to disconnect it. Thanks again and enjoy the weekend.

Reefing line(s) run from pad-eye up through cringle in sail, down to cheek block and then forward to a winch on the starboard side of the boom. This assures that the reefed foot of the sail is pulled taut against the boom. A bit ugly, but effective in keeping the sail flat.

Message-ID: <50f18710-e207-4311-ae89-32e382de8...@postaudio.net> Content-Type: text/plain; charset="utf-8" I?m coming down on the side of a ground plate for LORAN, as somebody else mentioned. If it were my boat, I?d probably pull the plate at the next haul out and repair the holes in the hull. As far as a ground loop goes, they?re pretty common in audio and RF systems; I?m going to stick with audio as that?s my experience base. Let?s say you have two audio devices a ways apart, each powered by a local AC outlet. You connect an audio path between those two devices, including a wire that attaches the ground points of each. If there?s any voltage differential between the AC grounds of the two devices (more common than you?d think, for a variety of reasons), you then get voltage trying to equalize itself over both the AC grounds AND the audio ground you established when you connected the audio run. This will manifest itself in a buzz in the audio, generally at 60Hz and its harmonic frequencies (120Hz, 240Hz, etc.). Basically any time you have voltage differential with two different paths between devices, you can have a ground loop. I also agree with Joe about having everything terminate for ground at the engine; I usually advise putting in a Blue Sea bus bar with a single large wire to the engine, then terminate the grounds at the bus bar. It makes things much cleaner, and usually much easier to work on and more reliable, as you don?t have a hole bunch of wires subject to constant engine vibration. ?

The wiring was in frightening shape when I bought it back in October - much of it was corroded and probably original, and there were numerous "bad fixes" that I didn't like the looks of. So, I ripped it all out and started anew with a whole bunch of Ancor marine wire, a BlueSea panel, BlueSea fuse blocks, and went about re-wiring. > > All negative wires connect back to the nut at the back of my A4 motor, which is also connected to my battery negatives.
