    Flickr is working again for me.
    Here some pictures as promised.

    That is how it looked with 4 coats on. The starboard side is allready sanded.

    IMG_5449 by MistamastacaptainSir, on Flickbr /> These little helpers came in very handy.
    With that pump action spray bottle I sprayed the shed floor twice a little while before I started painting to keep the dust at bay.
    Using a piece of coated plywood as a pallet helped a lot to have the paint roller evenly loaded.

    Thanks guys.
    I´ve never used a paint like that before. Fantastic stuff.
    I´ll be on tour a few days, but as soon as I´m back I´ll be in the shed again.
    A bit tough to go to hollidays right now.
    One more coat, and then I plan to assemble the mast, the sliding hatch and the handrails.
    Looking forward to this.
    Cheers

    After thinking, that this painting and sanding would never end, I came to this



    I the end I had to do 6 (not 10 Mike, but I wasn´t sure either hahaha) coats to get a finish I liked. I
    left the paint then to cure a few days before I went into the shed again.
    After long weeks with no visual change suddenly things started to move on.
    Putting on stuff then was much more rewarding and good fun.
    The sliding hatch and the skylight went on




    The mast got the rings and hounds glued on. I want to use as little screws and holes as possible in the mast.
    Here I made a change to the original design and made the mast 30 cm longer with one additional mastring for a genakebr />

    This one got a unidirectional tape around the mast to prevent sliding down


    More to come soon.
    Cheers

    Thanks mate

    Here is another shot of my sliding hatch.
    I like the shape very much.


    With two helpers we got the handrails mounted with no thrills.
    I was a wee bit nervous if the server bend would end in some damage.
    I had it prebend on the floor for months now, but when taken off the blocks the rail sprung back to nearly straight.
    But all went smooth and easy.
    I drilled the holes from above through the rail and roof and screwed then from the inside.
    The tiny holes on top will be filled with thickende epoxy matching the color of the teak.
    I´ve been doing this for before on other boats. The filled holes are not invisible but won´t be noticed.
    I like it sometimes better than wooden plugs.

    That paint finish is amazing! Looks like the Perfection Pro is specially formulated for roller application, and as you say, a completely different beast from ordinary Perfection.
    And not available in NZ - the UK site I looked at said it was mixed to order, so maybe it has a short shelf life? They also didn't list that awesome green.

    Love the hatch as well but I'm unclear how it keeps water out if it's just Lexan in a channel. If I can understand it I may want to use it on my Seabright 33 build.

    Pete, here in Germany they have some standart colors in store and dealers that mix many different colors in short order.
    I can shot a picture of the paint booklet with all the available colors tomorow at work for you.
    The guys from International Yacht Paints here in Germany are very helpfull. Maybe you should try to contact them.
    The shelf life is said to be a year, but I had the paint longer before I used it without trouble.

    Your right Rigadog.
    At the moment it wouldn´t keep the water out.
    There is still a frame to be made of teak strips.
    That will be glued around the entrance to chanel the water aft into the cockpit.
    That ´ll be done in the following days.
    But before I´m gonna check if the centerboard fits, and start then filling it with lead shot.

    Greg, quite some folk that visited my shed asked allready if the boat was made of fibreglas
    A mean mind could call it a woodfibre reinforced plastic boat hahahahaha.
    I probably overdid it...
    But man, I´m sooo happy.

    Time to build in the first hardware





    This was part of the preparation to get the centerboard mounted before it gets filled with lead.
    Next step was to lift up the boat poco a poco with an jack old as ages.
    I have no idea how old this rusty little bastard is, but it workes like a charm



    When reaching the needed clearance to get the centerboard into its case I added some diagonal bracing to secure it.
    No need to get reckless right now.
    Even though I was confident that all would fit, it was great to see it did. Specially after I read about troubles of centerboard slots that got to narrow. All was fine here.




    The hole for the lifting line got a piece of stainless tube inside to spread the loads evenly.


    After I was sure all was fitting well it was time to fill the centerboard with lead.
    first I tested how much resin was needed to fill the leadshot. I wanted to be sure that no voids would be in the core.
    With 2mm shot I need 55g resin per 1Kg shot.
    A sturdy rack was build to hang the centerboard for the filling.
    The centerboard it self got some kind of corset to keep it from widening while the heavy lead is poured in.


    I decided to go with 25 kg lead per round with a break of a few hours in between.
    The first round was a bit messy until I went for a propper funnel. That did the trick


    I´m pretty curious how much lead I´ll be able to fill.

    Cheers

    The centerboard was filled to the rim tonight.
    167kg of leadshot got into it. Overall It is now 192 kg.
    Wonder how heavy that will be on the drumwinch when hoisting.
    I´ll tell ya soon

    Hi Max,
    If the Cape Henry relies on its centreboard for its main ballast, will there be some way of locking it down? You wouldn't want it crashing back up into the hull if you have a knock-down.

    Will it be pinned down to guarantee recovery in a knock-down, or left loose for relief in case of grounding?

    Hey Guys
    Thanks for your thoughts.
    Yeah Mike, that will keep my arms strong...
    With a 1:7 drum winch and the pin holding some of weight I hope that my guess about 22-25 kg to pull is right.
    That should be ok.
    The original design calls for a 150kg, 25mm thick galvanized steel plate.
    So I will save 42kg on the inside ballast, and leaves me the weight at the right place.
    I have actually never thought about some pinning or locking down that board.
    The danger with a 150kg steel plate would be the same and I don´t think another Cape Henry 21 has it.
    At least it is not in the building plans.
    But it is a good point I will strongly think about it. Love to work out things like that.
    The pinning shouldn´t be to solid though as I´m sailing sometimes around shallow sands.
    For that reason a board sliding up if the water gets to shallow is absolutely wanted.

    Cheers
    Max

    It's worth a thought, but I admit I haven't been able to think of a good system for pinning the c/board on Kotik. The top of the case is very close to the water line. It's a requirement for trailer-sailer racing here, as there have been a couple of boats sunk that way in recent years, but we don't race, and most of Kotik's ballast is built into the keel (360 kg in the keel, 25 in the board). You're probably not going to capsize in shallow water either.

    This is a fantastic build, Max. This boat will be a piece for the furniture saloon or for the boat builders' school exhibition hall, but not for the sea!

    Thanks Thomas, but no worries, it´ll go to sea

    This weekend after adding some more bracing to withstand the forces I lowered the centerboard carefully down on a little cart (not visible on this picture).
    Boy, that little bastard could get some momentum, so I played everything save with two ropes to lower it. Just in case...
    That thick foam on the cart was used as a spacer to get the height of the building frame, that still is fastended to the floor.



    I pushed it over the frame and moved it onto a second foam pad.
    Then a crow bar was used to put pipe sections unter it. Easy to move now.



    Well that had been the easy part.
    To put it into the slot I used a whole lot of different tools.
    The drum winch helped a lot to get it vertical under the slot.
    Then a wooden beam as a lever, my little jack and patience did the job.
    Poco a poco it went up. The emerging gap was filled with pieces of foam.

    Finally the board was in and high enough to meet the centerboard pin



    The pipe sections helped a lot too in this situation. Made it very easy to move the board lengthwise to allign the holes for the centerboard pin.
    That was a fun day.

    Cheers

    Thanks Guy

    The force to pull up the centerboard is a tiny bit on the heavy side but absolutely manageable.
    Unfortunately the roller on top of the case got bend allready. Is says to have a breaking strenth of 4ookg. Probably It shines more at tension and not at compression forces.
    I´ll build my own from some stainless angle iron.
    Next steps will be working on the hatch framing.

    Cheers Max

    So here is the new home made roller and the crooked and bend first one next to it.
    Made of 5mm stainless angle iron, this one will withstand all brute forces



    Meanwhile I worked also on the framing for the companion way
    The inner frame is made of 10mm ply and will be epoxi coated and painted once it is finished.



    To shape the upper frame, made out of some teak, I had laying around for years.
    Using that little adjustabel ship plane I made came in very handy once again.



    Set to the wanted curve, it planes away all lumps and irregularities like a charm.
    Wasn´t my own idea though.
    Inspiration came from the maritim museum in Picton some years ago.
    Here I use it on some kind off shooting board.
    A board keeps it parallel to the bench with some nails on that board to hold the teak in place.



    Everything dry fitted for the first time.


    I glued in the teak framing today using flexible ms bedding compound.
    A 1/32´ gap was scribed and cut at the joints to prevent squeezing out all glue and starving it.
    That way it will be waterproof for years to come.

    Another handy helper I used today are these syringe tips I bought cheaply from amazon.
    I think normaly they are used to refill printers or e-cigarettes.
    I use them with thickened epoxy to fill tiny holes .
    Sticking them all way down into the hole and filling it from the bottom up makes sure all is propper filled with no air trapped in.
    I couldnt make pictures in action whitout getting glue all over the camera, so I shot this one after the work was done and the syringe allready cleaned.
    Sometimes I like a filling holes like this more than using wooden plugs.




    Cheers
