First steps to junk rig conversion

    There is little tension in the luff, so with reasonably heavy battens of aluminium alloy or timber, most users find that they don't need downhauls. With light battens of carbon fibre, you might feel a need and could add them, but otherwise, it's probably a subconscious urge towards retaining the tensions in the bermudan rig that ought to be resisted, if possible!

    Hello everyone again. At long last I have finished my shed, built a sewing table and bought an old Singer 237 sewing machine. I've completed a sewing class with some really nice ladies, inviting them to come for a sail when my new rig is complete. I saw that there was a thread some time ago about someone else doing a junk rig conversion on their Flicka sailboat. There also is a junk rig option when the late Bruce Bingham drew the Flicka plans. I will be starting to draw the sail panels soon, using Arne's very helpful articles. I just have a query about the rig, and wonder if anyone can help? When a junk sail is reefed, how do you keep the reefed panels from being lifted up by the wind. I can see that the sheets will keep the clew down, but at the tack there is nothing to keep the reefed battens from lifting, unlike the boom, which can have a tack line. Am I missing something? I forgot to mention, for my first effort I will be using 150 gm ripstop polyester fabric. Best regards, Oz.

    Sweet little boat. Nice shed too. Looking forward to a photo record of your conversion.

    Hi Graham and Paul, first, my apologies for the late reply. My shed is nearing completion and my first project will be to make the tabernacle for, I hope, my junk rig mast. My thinking of a fibreglass tabernacle was that instead of a timber one, then sheathing it with Epoxy and cloth, I would make the whole thing out of vinyl ester resin, glass matt and woven roving to a substantial thickness. The finished tabernacle will extend from the boat keel to about one metre above deck level. In all about 2.3 metres. I have included a photo of my home built boat and of the shed. Best regards, Oz.

    Hi Oz,

    your project sounds interesting, and I'm sure many will follow your progress. I am especially curious about your grp tabernacle.

    Would you mind to share some details and fotos of your selfbuilt boat? 

    What is your current state of the junk rig conversion?

    Best

    Paul

    Thanks for posting, and I am sure I am not the only one who will be watching your progress with interest.  I have completed two junk rig conversions now, (Arion and Blue Moon) and when the funds permit, plan to convert my current yacht, Arion II.  Following the progress of others is always inspiring, and you never know what clever ideas you may come across.

    Hello everyone, I am hoping to convert my home built sailing boat to junk rig. I've read and re- read the junk rig hand book, read Arne's articles on making a cambered sail and made a 1- 20 scale of what my idea of the sail would be. Although this seems far removed from a conversion, the first step for me is i've started building a 30 square metre ( this is the maximum allowed without requiring planning permission ) shed. This is so I can build a fibreglass tabernacle for the mast and have enough room to make the sail. It's not possible for me to do things inside our home as my wife is severely disabled, hence the shed. I know it will be a long process, but I hope to have my new rig by next summer, God willing. If any one is interested, I will post photos as I get along. I will try to put a photo of my scaled sail. Best regards, Oz ( Asim  ).
