Posts: 3 03/27/06 02:07:21	Tags : None Dear C42 Owners, Our C42, hull 463, is the 3-cabin version and the alu Isomat mast passes through the deck in the owner's cabin, right against the pillow of the pullman berth. So when asleep (or trying to) the skipper's ear is at only 4 inches close to the mast and with the slightest motion of the boat the mast becomes a terrible noisemaker. I don't suspect the halyards running inside to be the cause of this noisance because we can tighten them on the winches and stoppers. The villains are the electrical wires : all or some of them are dangling loose inside the mast (top-, steam-, decklight, radarscanner,windspeed and VHF) and with the slightest rolling they produce a sound as loud as a churchbell. Can you advise me how we can silence this mast properly and what budget would be needed; Wilf & Katrien o/b Pegasus, Nieuwpoort, Belgium

Every time I meet a C42 owner they have the same problem. I can't speak for your boat, but for me (hulll #519) it turned out to the halyards and not the wires as they are in conduit in the mast. No matter how much tension I applied to the halyards the prebend in the mast meant that the jib halyards were just skimming the inside of the mast for much of its length. I have not found a solution but instead wear earplugs when at a rolly anchorage. Anybody have any solutions out there? Mark #519 www.salacia.ca

The wiring you've identified is normally routed through PVC conduits when the mast is rigged prior to commissioning. It's difficult to run wiring through the conduit after the mast is stepped so there's always the chance you have a few wires loose in the mast. As Mark points out, halyards are often the culprit. You can verify that by loosening the halyards and seeing if the sound changes. You can also cover the mast to deaden the noise. Check the Craftsman's Corner on the C-42 Org home page and take a look at Garry Willis' teak mast enclosure. Alternatively, a layer of foam backed vinyl with a zipper or velcro closure will help. Good luck. Larry Melelana Catalina 42 # 175 1990 3cbn, wk Solomons MD

However this was not the case on our C34 tensioning the haylhards only made it worse so I tried loosining them , try slacking off on the tension, it may be that you have to find the "sweet" spot , in our case the tensioned lines were acting like a guitar string. Any how after playing aroun withe the tension allmost all the noise disappered. Dave # 810

It was brought to my attention that the rake of the mast provides a mid point bend for the cable run to hit at the bend. Tension of the halyards doesn't make that much difference. I had them tight, I had them loose. Get use to it. However, the creeking that comes next...try this. I done several different things. First I put some WD-40 behind the mounting plate for the goose neck (Mast attach point) that helped a bit., next, we sleep with or feet towards the mast...and yes we survived, and last, before I hit the sack, I go on deck and tie a line around the boom, just over the traveler, and tension it to a hand rail, just enough to keep it from swinging at all. Then go to to bed. Banging halyards, yes, but no creeking of the boom. Rick, Troubadour, Catalina42 three cabin

Posts: 310 03/27/06 21:25:41	I find that my club burgees cause much more a racket than the mast/halyards do...... I have perfected my "night routine". I am very strict about performing my "Catalina De-Clanging Dance" topsides --- in each and every harbor we hit..... before settling in for the evening. My husband just watches and shakes his head. Oh to sleep through trains and thunder and babies crying ! Sometimes the dance resumes at 1-2 am if the wind picks up. Oncore -- Oncore !! I won't mention what I am wearing topsides..... but the dance is done with a small flashlight held firmly between my teeth, bungie cords in one hand and pliers/WD 40 in the other -- moving in a circle, sometimes getting very cold, --- the dew making the deck slippery as hell !!! Ocassionally now, I am joined by my wee black dog who shocks the devil out of me when he bounds up topsides. He really thinks I am up to some adventure in the cockpit without him. Isn't sailing something ? Anonymous First Mate -- earplugs and sleep mask too !

Posts: 55 03/28/06 08:47:29 Moderator	Hi Wilf & Katrien, My C42( hull #837) is a 2 cabin centerline version so our bunk is too far from the mast which runs down inside the forward head to hear anything. BUT, when I was recently installing a new radar system, we found that the conduit carrying the wiring had not been secured at the masthead and was bunched up around the base. That could be your problem - a trip in the Bosun's chair could confirm that. Good luck Dick Butler Escapade #837
