    The added details like the hatches are a lot of work ,but they will add value to your boat and it's a way to make this boat special. The bottom line is if you like the look it's your boat and that's all that matters. When this boat is finished it will be the boat everyone wishes they owned. You two are doing an amazing job and most people can't understand how much planning and hard work it takes to build a boat of this size with all the added enhancements you've incorporated into the final design. It's looking amazing and I'm looking forward to see the end results.

    Good information. Hatches look great. I'm trying to not be a busy body, but.... I've made some really strong curved flush deck mounts (half circles under the deck) for my kayaks. These are known as Maroske Fittings. (I made a very poor quality video somewhere on YT about my variation.) I learned a couple of things. 1. Hot glue sticks make terrific molds. They bend tight corners without kinking. Two layers of teflon tape and slathered with release agent makes them pop off the finished tube. (The glue sticks stretch a little which makes them smaller. The teflon tape slides on itself. I've never had a fitting that wasn't absolutely smooth inside. Keep in mind that my fittings do 180 degrees in about 1" diameter - so tighter than anything most people are likely to need.) 2. Fiberglass/carbon sleeve - I can't say enough about fiberglass sleeves. So easy. So perfect. They're also very flexible so each size has quite a range. (It's been years so I can't be specific. You bunch it up a bit which increases the diameter, then slide it over the mold and pull on it to fit smoothly.) A lot of fiberglass/carbon fiber shafts are made just by slathering releasing agent on PVC pipe. (My experience is also if you give epoxy half a chance it will stick for life. I'm sure you're way past anything I know about this.) PEC might also make a good mold, and of course you probably don't need the tight curves I needed for my kayaks.
    I was just sailing on a 50' St Francis in the Bahamas where it was 'unusually hot' (My first time.) The one hatch we could usually leave open was over the owner's cabin shower (kind of like a mini bathtub). This is because any spray or rain just ran into the drain. That is something I will definitely look for; can there be hatches right over the showers? I kept making wisecracks about getting dorades.

  • @Tomm9y
    @Tomm9y 2 роки тому

    I would use a design of mould that included a slightly raised section for the hatch frame to fix to. That way the frame to fibreglass seal is slightly elevated from the base of the drainage recess, therefore the joint is more likely to be above water and less likely to leak. I know this would result in the underside of the recess being a little greater, but I think it would be worthwhile.

  • @lovingoz24
    @lovingoz24 2 роки тому +1

    Hi Matt, I am concerned that your drain holes from the sunken hatches are way too small. When sailing in heavy seas and constantly water coming over the deck, the water most likely will not get away fast enough and lead to hatch leaking. Another question, are the bulk heads strong enough as you know the Lagoon 450 have lots of issues with craking bulkheads and you building an unproven design are you sure these are strong enough?
    I have owned a Schionning Waterline 1480 catamaran (Eureka IV) in Australia for 5 years and done extensive fast cruising with her. Am a cabinet maker and handyman thus the questions. Watching your project with great interest and thank you for filming this amazing project for us all. Love the design of Max 44sc and think it will be a trend setter stiking that great balance between fast cruising and comfort.

    In terms of drying your shoes I found out a technique when my hobby was long distance running in the UK. It rains a lot in the winter in the UK and in the summer, you have to know how to dry your running shoes.
    If you take out the insole and put loads of newspaper or paper towels or anything that is really absorbent, and really force it into your shoe, wait about 5 minutes. Then take it out and repeat with some more newspaper or paper towel and really force as much paper inside as you can. Then take it out and the third time you do this leave it for a few hours. Then your shoes will be dry, maybe not perfectly bone dry, but dry enough for you to wear them again.

    Wet shoes. being in the BIZZ of working on luxury yachts in south florida. I KNOW the feeling. Now constructive criticism. When doing a spray job (gelcoat) AND the fiberglass job. Plan ahead, Wax the mold as needed entire mold. I prefer (mirror glaze mold release). After that is done, mask all inside/outside areas of the mold that are not likely to see gel or resin. All surfaces that will require gelcoat to be removed, should be masked on the mold with tape. Wax over the tape one last time. Once done PVA if you wish everything. Now after the gel coat job is done. pull the tape. I suggest using dog ears on the tape and I strongly suggest dbl layers. when ready to add glass layup there is no gel in the areas that would need to have it ground off. There is also a tape gap making it easy to get a plastic wedge in when removing the part from the mold. After removing the part from the mold it's 100% clean and ready to go for the next use minus some PVA cleanup on the mold and re-wax/reset. I do not use PVA on any surface that I'm expecting to have a mirror gelcoat finish from the mold. One more construction method TIP. When locating that hatch. Its better to use the two dot story line. Going off of the fwd bulk head. locate and draw your cut line as you did. Now on center (anywhere inside the cut out) Using a corner square, mark two lines in a row. drill set location holes on that line. top side you now have a FIXED location to reference off of. I also like using the hand held drill press. A drill press pluge adapter for things like cordless drills. Makes nice straight holes.

I would like to purchase a battery portable air conditioner, but an evaporative cooler would just raise the relative humidity.

    Are those fancy flush deck hatches really a good idea? One thing, the drains you glued in are not flush with the bottom so there will always be water akkumulating and stay there. Now you open the hatch and will get wet and also like e.g. bedding underneath the hatch. The good old aluminium hatches if somewhat protruding are IMHO a way more useful solution and just need a cutout for installation.

    • @MJSailing
      @MJSailing  2 роки тому

      The drains are below the level of the mold. The flow is forward, to each corner, and to the drain. The benefit with flush hatches are that waves or high pressure water is not going directly into the seals due to the deck blocking that flow.... It's an issue with normal hatches.

      Each builder is going to be different on where they would like their hatches and of what size, so Max Cruise does not add them as part of the mold. 🙂 Plus, other builders may not want to go with flush deck hatches, but instead the regular raised ones. That's the great part of the freedom of building this yourself.

Plus, on this catamaran, we'll have even more solar power, allowing us to run our watermaker more frequently. 🙂

    Do the boats built at the factory have the flush mount hatches? Or maybe an option as to which way you want, with increased cost if you want flush mount? You would think if they are always flush mount, they could have made that in the mold of the deck to begin with.

    • @MJSailing
      @MJSailing  2 роки тому

      At the factory, they are making the production version with the flush hatches. The reason it is not already a part of the mold for the kit is so that each kit can be tailored to fit the person who is building it. Not everyone will want their hatches in the same places (or the same sizes), and doing the build yourself allows you the freedom to make those changes. 🙂

    Pretty disappointed that you would flog a $1500 A/C that can be duplicated with a $150 portable air conditioner with a $150 inverter.

      The innovative part is the weight, space and power use of the inverter based A/C.... It's also a dual hose system which I've never seen in this size. We have a 5k portable and a 12k and neither are close to as efficient with power as this system.
