    Thank you for the presentation and if there was one thing you should mention here is that is the result of Parley Revival's trials to fix their Lagoon after the bulkheads revealed design and execution flaws. Build quality is vitally important and I am glad Privilege takes that seriously .

      Agree that this topic was very much brought to the forefront by parlay revival but you can’t honestly think one manufacturer is going to get on RUclips and start bad mouthing another? That’s silly.

    I don’t have a boat, and have no plans to buy one. But I enjoy watching Parlay Revival’s videos. I believe hat Colin has done a tremendous service for Lagoon owners. He has shown structural flaws in those boats that could cost lives if not addressed.
    So, I’m glad to see other catamaran manufacturers showing us how their boats are built. You are showing us the bulkheads without some poor owner having to tear up their precious and expensive catamaran to see what secrets lie hidden in darkness. These cats look amazing! You obviously are proud of your boats! I wish you continued success!

      Of course they have. But few consumers really seem to understand carbon. Carbon isn't magic, it is simply stronger for a given weight than fiberglass. For most bulkheads, why would you do it? It's in a place that doesn't need more strength than glass provides, and it's in the lowest priority location for reducing weight. Carbon rigs make the most sense to lower the center of gravity. Carbon may make sense in supporting large openings or spans that simply can't be done strongly enough in glass, like a cantilevered bimini or something. But on a prioritized basis, most bulkheads will only be all carbon in an all carbon boat trying to save every last ounce. You'd get a similar effect by packing boxed wine vs. bottled, or limiting yourself to only 6 pairs of shoes etc.

      @@secondstartotheright Cool, and I tried to explain why not. It's because foam core glass is strong enough, and any desire to save weight will be done elsewhere first. Typically higher up and/or where long spans can benefit specifically from carbon's stiffness. Roughly speaking, carbon is 5x the cost for -15% weight OR + 20% strength. That's a better investment in a mast or dagger board than it is in a bulkhead.
      It may be worth noting that the lagoon problem this is obviously responding to isn't because their bulkheads aren't strong enough. The lagoons just weren't fitted and attached well. Which is why that is exactly the focus of this video.
      If parlay revival had been made with carbon fiber bulkheads it still would have fallen apart.

    3 questions:
    * Have you built an aluminum version of any of your boats? Explorer style?
    * Why not throw on a sheet or two of carbon fiber over the current side bulkheads' foam core panels? There are only two main bulkheads and the extra rigidity will save cracking throughout the whole boat over time.
    * When are you going to design a dry foredeck catamaran similar to the Bali/Catana line? Seawater spray equals salt and constant nuisance cleanups with freshwater washdowns. I've also seen Priviledge front lockers flood badly. Bali's 5.4 "higher above the water" design - came in fifth in the ARC Rally in 2015, so the design does not impede performance nor sea worthiness. I'm not crazy about Bali's top deck stair access (its too exposed) but otherwise it's spacious, works well, and gives you the whole boat that makes every inch usable.

    The lagoon 450 bulkhead fiasco is not giving potential catamaran buyers much confidence about other boat builders are any better. I alway like the Privilege 510 and this video did answered some bulkhead concerns. Only time will tell if this construction method will hold up in real sea conditions.

    Cutting a cured fiberglass sheet in it self is worst than using the lagoon style bulkheads.
    Edit: apparently there's no CNC cutting or whatsoever since your boards are all cut with a jigsaw as seen here 0:44 here 0:58 and here 2:03 etc..
    2. Love those finger cutting fans on the master bed, especially when it's dark and you want to shut it down. Good job!

    Very Nice! -- QUESTION -- One thing we learned when looking into one production builder, that has had enormous bulkhead issues, is that they claimed to build to a standard, but when you are not watching them build it, they skip important steps. It just seems when no one is watching them, that they cut corners. This may be because of lack of care or even lack of training or skills and, maybe even a level of dishonesty. When their boats were inspected during the construction phase by independent inspectors, the construction was much better. This is a big issue. I suspect that Privilege has much tighter controls and inspections of crucial steps in construction as I have never seen a failure or deviation on those parts on the boats we looked at. My question is this: do you take pictures of the key bulkheads before they are covered up, as part of your manufacturing control function? If not, you may wish to adopt that simple step. Most modern manufacturers now take pics of key components and keep those records on file in case of claims made in the future. It is an excellent way to protect yourself and the customer.

    This is the type of construction specified by Derek Kelsall in the 46 footer I built. Most production catamarans are basically wooden boats with a skin of fiberglass with all the attendant problems of wood in a marine environment. There was some talk about shroud tension contributing to the bulkhead problem. Have you considered shroud tension?

    Excellent build quality! -- QUESTION --- We just watched this weeks episode of Parlay Revival and saw the horrible deck joint failure on that Lagoon. A factory installed line block connected to the bow deck, pulled apart the deck from the hull and lifted a three foot section clean back. This happened in only 12 knots of wind and exposed the front hull to the ocean. Turns out it was lightly glued to the hull and in several sections they had failed to apply any glue at all. Total nightmare. How does Privilege connect the deck to the hull and are they aware of the importance of keeping that joint completely attached and water proof? Parlay could have sunk had they been in an Ocean crossing. This Lagoon Cat needs to have the entire deck completely removed and reattached properly (if that is even possible).

    • @PrivilegeCatamaransAmerica
      @PrivilegeCatamaransAmerica  9 месяцев назад

      Hi Coleen, if you've watched any of our production videos you'll see that we don't glue and screw bulkheads, they are fully glassed. This is also true for the deck and hull joint - they are glassed in and become a 'holistic' structure. It would be virtually impossible to take the deck off a Privilege in any wind conditions,

On the carbon structures, is it one layer of carbon fiber per side of foam? For the paranoid among us, can we order it with more layers??

      @PrivilegeCatamaransAmerica  10 месяцев назад

      Great question and your paranoia is born out. The very thing that differentiates one yacht builder from another is rarely the thing people take any notice of at a boat show. The FRP layup methodology is critical to a well built vessel and is much more complicated than how many layers of fabric are used. We have included discussions on this subject in some of our earlier videos. Again great question.

      @@PrivilegeCatamaransAmerica ...must say that the bulkheads look so nice compared to Lagoon's. Maybe I shouldn't admit this, but in my experience things that look good tend to be good. We are all taught not to think that way but rarely are neat, good looking construction methods actually bad construction methods. It is possible but I have yet to find such an example. When I saw how Lagoon put their boats together, with all that ugly adhesive gunk and very little fiberglass tabbing, I knew that it was a bad job. Your Catamaran construction looks amazing. Still not sure how many layers are on it but I am confident that there are enough.

For the electrical cables and hard walled plumbing, marine grade MCT’s would be the professional approach which are relatively cheap. For soft walled plumbing, bulkhead fittings could be used which are also relatively cheap.
      We see too many business these days cutting corners to save a few cents here and there that only serves to turn what would have been a great product into a cheaper product that is easily identified by the knowledgeable prospective customer.
      I encourage you to have the discussion with the builder to use the MCT’s and bulkhead fittings instead. Firstly they are more secure and are far more watertight (they are actually gas-tight), secondly are far better for maintenance, and thirdly are much neater which looks far more professional.
