      I think Mads is fantastic, it takes a lot to get out there every week and do this in his spare time. HOWEVER, I do agree with you that he has a tendency to find a part of the boat that isn't a problem, spend months over-thinking it, massively over-engineer a "solution" to his non-existent problems and then spend weeks implementing it. Meanwhile the real problems on the boat (the lack of a bulwark, the missing final coat of paint going into winter, the boats short 38ft size which is going to be very limiting) all go unaddressed.

      Thicker without increasing number of bolts and/or surface area is pointless. Wider would have made some sense structurally.

      @Robinlarsson83 2 года назад

      @@KarelvanBrederode no, not at all. He still gets a higher margin of safety on the chainplate itself since the cross-sectional area is increased by 20%, so the chainplate can take 20% higher loads, or get damaged 20% more.
      I can't remember seeing many chainplates fail due to pulling the knees or bulkheads they were mounted to out of the hull, atleast not on reasonably made knees and bulkheads.
      They usually fail around bolt/pin holes, in welds or due to corrosion, often were they pass through the deck.
      Sure, it was likely not necessary to upsize the chainplates a bit, but it doesn't hurt.
      A wider chainplate would possibly have been better, but may have other downsides, it would have provided a stronger connection to the the bulkhead due to a larger contact area, but that is most likely not the weak point anyway.
      Bolted connections like th doesn't really rely on loading the bolts in shear, but rather on the friction between the components, but how well that actually works between fiberglass and stainless may be hard to quantify. Probably a good idea to have a smooth contact surface on the composite.
      If the bolts transfered all the loads, we would see a lot more oval holes around chainplates :)
      Bolted connections often use slightly oversized holes to not load the bolts in shear.
      If there is one component on a boat were a bit of overdimensioning is more than okey, it's the chainplates :)
      I've seen rules of thumb that state they should be about 5 times stronger than the wire they support, and that you should be able to lift the boat in the capshroud chainplates, seems reasonable to me.
      The only dismastings I've directly experienced so far have be due to broken chainplates.
      In one the capshroud chainplate failed in a weld on a 28 foot yacht while going upwind in moderate breeze, the mast came down in 2 pieces very quickly :/

    I installed a Groco thru hull just like that with the same white Groco mounting disk. I used 3M 4200 to hold everything together, so the epoxy seems like an extra step to me. Also, when I took the old seacock out (also a Groco, but a different configuration they no longer make), I needed to remove the previous mounting block. That was SO MUCH WORK. So, it seems to me you have created a lot of work for whoever has to replace that seacock you just installed. The Groco I replaced was original to my 1973 boat, but who knows, you might still be sailing Athena in 40-50 years when that seacock needs to be replaced and cursing yourself for fiberglassing that disk in. ;-)

    Its coming along nicely Mads, One thing appears to be a glaring potential problem. The double chain plates, because they are so close together it will become a place for water to enter over time. Perhaps you might consider welding the two together, I know having to make a new double chain plate from one piece will be expensive, but,,,,, "an ounce of prevention is worth a pound of cure" .and now would be a good time to address it.

    The double chainplate (Cap Shroud & Intermediate Shroud) will eventually leak because the two pieces of steel are butted up against each other and sealant will be hard to get in there. Whats worse, that's the area where crevice corrosion will start to set in. There are two solutions; Ideally the chainplate should have been made from just one piece of alloy. Because you went with two, there should be a strip of butyl tape run between the two chainplates where they touch.

They have fitted hundreds of yachts with this now and have a plethora of super spiffy specialist fittings that fit with it too. NO CORROSION. FIT AND REPAIR YOURSELF. VISUAL INSPECTION. STRONGER AND WAY WAY LIGHTER THAN STAINLESS. Just a tip from a bushman biker in NZ. lol She IS a Spiffy Boat, Dude. Oh ps. After India trip, I bought a special spiffy hose for the toilet with a water valve on the end, no more toilet paper for me, and much more hygienic than the westerners method of smearing poop round till content.
    So I vote with Ava on that for your toilet. No paper, no blockages.

    I have to ask if you plan to utilize the dead space above the new floating fridge from the ceiling. I was thinking about this as it would be somewhere to "hang" a microwave as if you place the potential microwave in the cubby under the window, you'll cover up that little hatch you made (and found dead space in when ripping it all apart so long ago). If not a microwave, then why not a TV suspended from the ceiling in the parallel position to the ground and then pulled down when needed and put up when not used and out of the way. Run an HDMI cable from the TV, through the ceiling and behind the wall to the seating area, and now you have RUclips and Netflix hardwired in from a laptop or micro PC or even a NAS, filled with movies on it (which is my plan) for the long winter nights :) Fellow tech geek throwing ideas your way to mull over and ya never know... might love one of the ideas :) Cheers brother!

    We used butyl tape for our own chainplate cover plates on SVBD and have had no leaks now after 3 years.
    Your cover plates look MUCH more beefy than ours which had a little flex in them plus ours were not through-bolted. Instead we had to use very small #8 screws so we really could not put a whole lot of torque into them to get them super tight without fear of stripping out the screws just holding into thickened epoxy pockets (drill-fill-drill to protect the core.).
    I can physically see the plates bending down at the screw holes a tiny bit so I know that not all the force at the screws on the ends is transferred to the middle to press down on the butyl there tightly.
    Still, it is holding fast with no leaks so far. I was not sure it would work and was prepared to remove all the cover plates and use something like sikaflex instead to do the job, but so far so good.

    I think you need to put some sealer between the two chainplates where they touch each other, because water will go down into the boat through that tiny crack. My double chainplate is a single piece of metal instead of two separate units. That would solve the leak issue described above. I made my chainplates out of titanium so I never have to worry about crevice corrosion.

  • @joes7166

    My 86 Catalina has chainplates similar to yours. Originally there was silicone sealing them. One of them leaked. I have owned the boat for 7 years now and 6 years ago I dug out the silicone and replaced it with butyl tape. I sail in the Great Lakes and we hail out our boats every winter and take down the mast etc. Six years later, and a lot of flexing and temperature changes, no leaks at all. You should be fine.

    Hi Mads, obviously ATHENA closes in for splashing by the minute.
    A remark on the chainplates, as onother comment already mentioned the way you are installing the chainplates will lead to crevice corrosion. Even the highest quality stainless steel items suffer of it when there is no air flow over them. The sealing with butyl tape prevents exactly that. Now, you increased the thickness of the chainplates from 10 to 12 mm so it will presumably take maybe a decade before they fail, but fail they will. A solution to that problem is to make chainplate and cover in one piece, by welding or casting. Sealing is than done only around the rim of the cover which will also suffer from crevice corrosion but that doesn't lead to structural failure it's just cosmetics. Since both you yourself and Ava are still young and ATHENA is practically a new boat because of your incredible work, you might think about it.

    Perhaps a bevel on the underside of the chainplates would help compress the butyl tape and ensure a good seal. On the double chainplates you might need to put a bead of Sikaflex between them to seal water from seeping. Butyl is perfect for sealing chainplates and other deck penetrations, not because it seals permanently but because it is easy to replace. 3M 5200 is permanent!
    It is great to see Athena getting closer to splashdown. Here is hoping you get your needed weather window soon.

      You might be able to weld the two plates together to seal the gap. Since the plates are installed you can tack weld supports on them to hold them in position while you weld the gap shut in the shop. You only need to weld far enough down to get a good four sided seal with the butal tape. Just my 2 cents.

    When epoxying backing plates to the hull I would recommend clamping with the through hull (with plastic wrap!) or something you know is parallel. With a curvey and often uneven hull surface it is very easy to not get the plate level which at best means a wonky gap for the external skin fitting.

    • @SteelDoesMyWill
      @SteelDoesMyWill 3 года назад +1

      Awesome idea, bronze is so much better... but do your turnbuckle toggles still fit to pin onto the chainplates? If you have 1/2" or larger turnbuckles, the toggle gap should be at least 1/2". Life Caulk is fine, it is a flexible sealant. Long term flexibility is the key factor.

    • @curtislong4305
      @curtislong4305 3 года назад

      If I understand you correctly, I think everything should be fine. I maintained the profile of the original chainplates, and the pins were all 1/2" already, so in my mind, there is more bearing surface for the pins and they are more stable than the original rig because toggles that accommodate 1/2" clevis pins are wide enough to accommodate the thicker chainplates. TLDR: the old chainplates looked "wobbly," the new ones look solid.
      I'm sure the old setup was sufficient, but since the age (1974) dictated a refresh, I figured why not do it once and (hopefully) never again?

    • @SteelDoesMyWill
      @SteelDoesMyWill 3 года назад +1

      @@curtislong4305 Yes, you did all the right things. Bronze is not quite as strong in tensile than Stainless Steel, but it is more ductile. Going with bronze chainplates requires up-sizing from the SS original, but sometimes people forget to consider the hardware factors and upsize too much. That is not the case with your boat since you had 1/2" clevis pin and obviously 1/2" turnbuckles. Had your turnbuckles been 3/8" you'd be in trouble. Since your gear is that large, you probably should have had 3/8" thick stainless chainplates to begin with, 1/4" was too small for world cruising scantlings but sufficient for coastal standards.

    Looks like your going to get water in down between the double chainplates. I think a silicone type sealant would work better considering the chainplate will probably flex when under load and may open up voids with the butyl.

      Wouldn't it be simpler to make the doubled up chainplates into one double size chainplate with two connections? Then you wouldn't have to worry about water getting in between the plates. It would be all one plate.

    Butyl tape is absolutely the correct choice for bedding the chainplates. You want a sealant that always remains flexible and butyl tape does that better than any other compound. You are correct on beveling the edges to force the butyl to form an 'O Ring' seal around everything, but you don't have to make the bevels so deep and wide. You are correct in your observation that most of the butyl might get squeezed out because of the large bevels and that is likely what happened with the one that leaked. Keep in mind that 'O rings' are very small diameter while keeping things sealed (even in high vibration areas like the engine). To make perfect bevels I use small router bits on a trim router.

    8:26 For the holes that have 2 chain plates next to each other the water is going to leak down between them no matter how much you try and seal it, it's going to be a matter of when not if. Worse once a little salt gets down between them it's going to be a nice invisible location for corrosion to set in that your can't see or inspect. You would have been much better off having the fabricator make one double wide plate.

    The only problem i foresee with the butil tape is tied to the fact that it might separate from the chain plate whenever the chain plate is moving about, and they are moving with sway, tension, temp dif. etc. I'd squeeze in some butil from the top, into the gap of the chain plate and the chain plate guard. With a bit of soapy water, you can shape it nicely. That way, you're giving it a fighting chance (more surface area, thus less of a chance that a section might come unstuck. I wouldn't have shined the area under the plate either, to give the tape more sticktion.

    As a Shipwtight and Rigger, i enjoy your channel, and i can fault very few of your idea's, BUT, as many have already mentioned, the twin chain plate install is not good, as far as stopping water intrusion, ideally it should have been one plate, with two pin hole's, that way, there would have been no issue with water getting between the two plates, if you think about it, there is no good way to caulk between the two plate's, due to movent, when tensioning , and movment under sail, this can be salvaged by removing the plates and welding toghethet, e.g., making one plate, also, thru bolting, makes it difficult to re-bed the caulking, with out removing the head liner and un-bolting, better to use a screw fastning. Keep up the good work. e.g., interested in the fridge system you will be using, as i am a refrigeration mechanic. Allfernow, Doug.

    My boat’s chainplates leaked after only a couple of years from factory, a reputable Skandinavian boatyard. Sealant was some sort of polyurethane. That lost grip of the metal because it was polished. I fixed that by taking the shine off from the chainplate with fine grade sandpaper (not that glorious sanding) just where the sealant sits in the deck. That was 10 years ago and no leakage so far. Regards from Finland, we enjoy of the same weather here!

    Mads, I do exactly the same. I get someone to hold the skin fitting on the outside (to a pre-made mark) to stop it turning and then screw the seacock on from the inside.
    However, I've seen people do the opposite with no problems at all.
    So maybe it doesn't matter too much.

    Hey mads, two things. First I just got done redoing the deck of my Catalina 22 alone and found that a vice grip with a piece of cut open tubing was a great set of extra hands that I knew would not fall off. Second, if your chainplates do leak, is there a reason that those pieces of trim need to be separate? I would do a quick tack weld while they are in place and then take them off and weld them into one big piece. That way it could only leak around the trim (now a flange) which WILL be sealed with butyl under compression. I did that with my boat and it looks “super spiffy”. Cheers

    • @craigs5212
      @craigs5212 3 года назад +2

      I was thinking the same thing on the chain plates. But worry that any weld may cause a stress riser in the weld area making them more prone to cracks at the weld under working loads and continual bending moments. Possibly brazing or post welding heat treating would make this a non issue but it's a great idea.

      Also, the chainplates move. Right now that stress is transferred via those big bolts to structural members in the hull. Welding the flanges means those stresses will be transferred to the deck via two small bolts. Something bad will happen.
