Newbie - Did I waste $1700? Mast kink on Mystere 6.0  Bottom

Go to page [-1] 1 - 2 - 3:

  • I think mine had the same setup as you are describing. The threaded rod does not have to turn in the barrel it’s anchored into.
    Undo both top & bottom nuts. (They will turn opposite way to loosen). Then hold the “flat spot” Andrew alluded to, I use a crescent wrench, & turn only the barrel, via a thin pin punch in the barrel hole.
    We used an awl a few times, but twist it firmly in, & be aware they can break.
    Heat the barrel with a propane torch, just enough so the heat load doesn’t fully transfer into the threaded part of the wire.
    If all fails, (you should probably source new standing rigging anyway), cut them off
    Thus photo is from an album I made showing the complex line rigging for the jib, but you can see the Diamond wire anchors.

  • QuoteMy biggest worry is breaking the deck panel or the "shelf" it sits on trying to get the panel of

    Looking at your photo of the half removed panel, I see what looks like chips from the tool the po used to open the deck as far as he thought necessary to do the repairs. He did some patching, got discouraged with the results and abandoned the project. Time passes and he’s lost all interest in the boat and puts it up for sale.
    Now it's your project. You have to decide if you can do the repairs with the access you have or do you need more room to do it right. The hardest part of getting the deck off is the first couple inches. He did that with very little damage to the panel. It can be done. Sharpen up a scrapper and give it a try. If you damage the hull side it's easy to reinforce it from the inside with some fiberglass and resin, the deck is a little harder to repair. It's very important that the scrapper you use is sharp. Knife edge, not blunt.


    Quotewd40 is not gonna do anything on stuck fittings on these boats - you need Blaster if there is any corrosion involved

    Word! Get pb blaster, kroil, or automatic transmission fluid and acetone mixed together and hit every fastener on the boat, repeatedly. When reassembling coat mated surfaces with lanocote or tefgel.

    Yeah you need all new standing rigging if you haven't heard yet. Say hello to Murray's for me.

    Murray's doesn't have premade rigging for a Mystere 6.0 but if I measure what I have, I assume they can remake it? The shroads appear in pretty good shape. Should I replace these for good measure anyways?

    I was able to get it off and take a look at the bare mast. The bend is still there but when we put it up on to some table gravity brought the mast back to straight so it should be fixable right?

    There are two things I'm trying to figure out in the hulls. I have gone around with a spackle knife, hammer, and razor blade to get the panel off but I can't get the panel off past this point. It seems to be glued down or fastened around the centerboard cutout. I have gotten the knife under the edge almost everywhere else but this is as far as I can take it off.

    Lastly, as I have been looking in the front of the starboard hull, I can see some light coming through the base so this will HAVE to get patched. I assume fiberglass to reenfore the weak areas and cover any hole is the right proceedure here? Should I also look at re-covering the outside with gel coat or filler? You can't see the gaps in this shot but I wanted to show the space I will need to work in.

    you should replace all old standing rigging diamond wires, side stays. bridal wires and forestay or find a local rigger, there are lots of options here.

    This looks bad to me, you have a bend and a twist. Where are you located? If this was me, I would have a professional rigger do a marine inspection on it. If that isn't an option, have your uncle evaluate. IF just a little weight in one spot corrects everything - you have nothing to do = you will have 100's and 100's of lbs of rigging tention as soon as you rig it and sheet in. that will auto fix a small bend - as i said - it looks worser than that to me but your pics are pretty hard to see a kink 20' away in low res pics and i am not a professional marine inspector

    Some light is not a big deal, there are thin areas
    IF they are worn down, through the gel-coat into any fiber - yup need to fix that.


    you need to do some research here
    i highly recommend the west marine video tutorials for an understanding of what a fiberglass/ epoxy work is gonna take

    others will chime in too i am sure

    Does "nothing to do" mean good to go or "nothing to do" as in there is nothing I can do about it and it is trash?

    I read that as you are good to go. The force to straighten it is roughly zero, the forces on the rigging will be large. But, I can also read MN3's reply as doom and gloom.

    My only sailboat work has been on our H16. So I'm not a rigger. I've done a lot of work with aluminum on aircraft. From what I can see, and if it was my boat, I'd probably try and tweak it straight and true with the wires off.

    I did replace the mast on my H16. Not because I had to, but because I bought a parts boat for hulls. It had a better mast hound, no cracks for the stepping hinge, and later I found out the halyard sheave was much better. So that is always an option too - look for a mast.

  • a little bend in a mast, not under load MAY be fine under load. when everything is sheeted tight and the mast has force on it, it doesnt impact the integrity and would cost time and money to "chase" making it look straight on land

    IF a bend, kink, twist, corrosion, or other is in a location or with a level of severity that compromises the mast under-load, you need professional help. Hopefully you can find a marine welder/fabricator/rigger to do any

    the cost of the work could quickly pass the value of a replacement mast (est $1000 to source a new/used mast give or take)

    been thinking about this pic

    I see an issue - you are missing all your bulkheads

    you should see a bulkhead about 2' forward of the deck port and there should be a horizontal one too creating an inclosed box under that deck port. there is another bulkhead missing forward of that too - I can see where it used to be

    if you recall i mentioned earlier that it's a known issue for the bulkheads to fail - my 5.5 forward bulkheads were fractured and looked like they were hit by lightning. Lots of flex and torque going on in these hulls

    if you get the deck lids off - it's not that hard of a fix assuming time, money and skills are available

    You can see the 2 bulkheads in this pic of my 5.5 (note the 5.5 does not come with the horizontal bulkhead)

    http://www.thebeachcats.com/gallery2/main.php?g2_view=core.DownloadItem&g2_itemId=123659&g2_serialNumber=6

    If I am correct, these are the bulkheads you may need to recreate - this is when i was adding horizontal bulkheads to add extra stiffness to my 5.5 since i was in there replacing bow tangs

    yup. the bulk head fell down as I was getting the panel off. and the picture was taken just in front of the second one. I bought some fiberglass and resin which I will use to reenforce and attach them.
  • So I have gotten the entire deck up EXCEPT right where it connects to the front of the Centerboard well. Looks like the PO put a bunch of glue in beneath where the top panel wraps down into the opening. I can't get a scraper or chisel down there. Any suggestions for getting that up? My first thought was try and use a long bar and come up from the bottom but I haven't tried it yet.

    I was talking to someone and they said to just cut the thing with a dremel and repair the fiberglass which seemed extreme but is a better alternative than missing something and having the hull fill with water.
  • We don't know what kind of adhesive was used, however Marine Debond formula will go through very tough adhesives like 3M-5200 with time. It won't dissolve epoxy or resin bonds. It might be worth spraying it into the adhesive and see if it softens.

  • Look closely at mn3's photo of his boat with the deck off. It looks like there's a big wad of resin at the place I think you're talking about. I think you've arrived at the hardest part where you're most likely to break the deck. I like your idea of a long bar (sharpened of course) coming up from the bottom. You have to make your own tools and try to make the cut where the glue meets the inner surface, that's its weakest point. It's easier to reinforce inside the hull than repair the deck.

  • Your mast bend to totally fixable....I have straightened the mast thru leverage with fixed points and bending slowwwwlyyy...! Then get another small section of mast that fits your profile...cut small section ...then rivet it on top of the bend....it works...
    Did this on my 24 ft seawind...after rigger said it was not fixable...!
