New junk rig on Otterbelly + knots for battens

    An updates on the rig. Out in 20 knots this week (or as Arne would say, f5), great sailing but hard to control due to exessive weather helm as I had all panels up.  When I headed off the wind and was running it was still a little tricky but a very fun ride with a comparable sized bermuda boat alongside to make it extra interesting. Even with the added handicaps of towing a dinghy and with the outboard motor still lowered I was just pulling ahead. So it was until my extra-slippery polyester lines decided they weren't really that into my knots and bends, and at that moment I lost my upper sheetlet and aft lazy jack at the same time, and the whole rig blew forward and hanging down into the considerably rolling sauce. Yikes! With some scrambling and lots of holding on I managed to get it all inboard and sorta-rigged enough to get into some shelter, rechecked and refixed all the problem lines and carried on the next day in similar conditions with a prudent one panel reef, much better steering control, and no further problems.

    So here's my related question, and I know there's probably a good answer in PJR but I don't have it with me, what are the various options for fixing batten parrels and HK parrels to the battens? I've been using ashley constrictors fore and aft of the mast; these mostly work but a few have slipped out (annoyingly so but without serious consequence). I could sew up the loose ends, but wondering if there's other tidy solutions.

    Looks great Karlis, a job well done.  I hope you enjoy many hands of sailing with your new rig.

    The photo's through the binoculars are fantastic..... reminds me of photos taken through the periscope of a submarine :-)

    I am not an artist but I love the pattern the old sail cloth has been cut into with the old sail number placed at the head and even an old sailmaker logo near the luff.  I bet the original sailmaker didn't realize he would get extra publicity from a recycled sail.

    Nice work on Otterbelly.  This refit is inspiring to those who want a simple sailing boat for local waters.

    Talk about "bang for your buck" Karlis.

    Regards,

    David.

    About the mast, Oscar, thanks for asking.

    The mast was designed as a 8-stave birdsmouth with 20cm dia at the partners, glued with epoxy. The staves were constructed from scarfed 16' douglas fir 2x4s, but a much cheaper selected No2 grade that was no real savings since the wood was so much harder to work. Due to a mixup with the router bit that was shipped to me (6-stave bit labeled as 8-stave bit) and myself stupidly not doing a short test barrell, the staves were all cut with a 6 stave bit. At 6 staves the stave width would only support half the sail area, so I either had to start over or add another 6 shims to make up the difference, I chose the latter rather than purchase all new wood. With my schedule this set back the project at least 6 months, and the resulting fit of the staves was far less than perfect, so I made up the difference with epoxy and milled glass fibre. I didn't want to sheathe the whole mast but I did wrap a epoxy & glass cloth band on every meter to reassure myself that the thing wouldn't come apart. I'm still not 100% on it but it seems fine so far; the PJR & CPJR (Arne's diameter recommendations) I used are probably intended for much harder sailing than I'm going to do with it, so it should be fine. For now I've varnished it but will probably paint it later. I learned a lot through this process but wish I had learned about the aluminum/wood hybrid style (like on Fantail) earlier, or went with the solid fir pole I had planned on originally. 

    Not sure why I got all fancy with it, somehow the birdsmouth construction seemed like it would be easier than it turned out to be.

    Looks good! I love the idea of reusing old dacron sails. I have two old worn genoas and a mainsail that I can use when I re-rig, luckily for me they're all cross cut. Dacron should be a lot more durable than polytarp (and in my case also cheaper). Also, using binoculars with a smartphone camera is just brilliant, gotta try it myself. How did you construct the mast?

    Fine looking rig! Can see both Tyler and Arne influences.

    Karlis K wrote:I'd like to announce the completion of my Junk rigging project on my Buccaneer 240 "Otterbelly". The rig is a 6-panel version of Arne Kverneland's Johanna design from his CPJR papers. The barrel-cambered panels are made with used dacron from 2 old genoas. The mast is a 6-staved birdsmouth of douglas fir. The whole project took way longer than I had anticipated (almost 2 years with all interruptions), mostly due to complications in the mast build, but I learned a lot and am happy to be finally sailing it. I haven't done enough sailing with it yet to fully tune the rig or assess balance under different points of sail and number of panels, but by good luck some friends managed to get some photos with a smartphone through binoculars while I was on a first test sail. I wanted to share the new gallery here. Thanks so much for all the help from the JRA, particularly Arne Kverneland and also David Tyler.

    I hope I get to see her when I finally reach the Vancouver area. Well done!

    Thanks Roy. There's also a section about this in our Help pages.

    Meantime if members click on Karlis's name under the image in his post, they'll go straight to his profile, where they can click on Photos and open his 'Otterbelly' album.

    And well done Karlis!

    Hi Karlis,

    Your sail looks great and I imagine you will have loads of fun sailing Otterbelly.  I'm impressed with the binocular photos too, very atmospheric.

    Just one small niggle - the link to your gallery doesn't work.  You need to go to your profile, then click on "My directory profile" near the top of the profile page.  This puts you into a public view of your profile, and from there you can copy the links to your photos, which then have a "public" link.  Hope this helps, and makes sense!

    Roy.
