    Matt,

    my experience with Hasler-McLeod sails, with their full size fanned top, is that they need a quite clever anti-twist sheeting. Could I suggest you look up the sheeting described in “Junk Rig for Beginners”, page 5? This is the sheeting which is now used on the 48sqm sails on Johanna and Edmond Dantes, and also on Frøken Sørensen (20sqm). On Johanna and ED the use of a snubbing winch helped with handling the sheet forces. The winch handle is rarely used. An additional benefit with that 3-part sheet is that it makes much less resistance (than a 5-part sheet) when hoisting the sail. It also lets the sail swing out more easily in light winds.
    Anyway, good luck!

     

    Arne

    I have no sheets running to the top two battens, and the sail did like to get a good twist going. I yanked and fiddled with the sheets, but the sheeting arrangement seems to allow the higher battens to fall to leeward, with a subsequent tightening of the lower sheet spans.

    Congratulations on your first and successful sail.    Nice to know it all works!

    If you look at PJR, you will see that there are several choices when it comes to sheeting the sail.  You might find that if you re-rig the sheet, you can put a larger amount of pull at the top of the sail to reduce the twisting.  Of course, in certain cases twist in the sail is considered to help the boat make to windward.  It depends on the type of sail.  As yours doesn't appear to be fanned, you might have more success re-reeving the sheet.  However, with two reefs in F3, you wouldn't really expect the boat to point to her maximum potential.  From my experience, junk rig is the only rig where you tend to shake reefs out when coming hard on the wind.  They - usually - need all the drive they can get.

    When you post on fora, it's better not to put photos directly into the posting: Wild Apricot gives us a limited amount of data and photos use it up.  Far better to post any photos under your profile in an Album.  (Go into Edit profile at the top right of the screen, then to photo albums and create one).  This makes it easier for readers to find, too, if they read the relevant posting a long time after the event.  Even under Illustrations in the Technical Forum, photos tend to 'disappear' as they get older and older.  

    I'm looking forward to hearing about the junket in Brittany.  You will be able to pick some experienced brains there!

    Hi Matt, I cleaned up your original posting a bit and placed the full size original photo  in the Technical Photo's gallery.  BTW also known as 'Illustrations'.

    Thanks Arne. You're right - it's pasting in pictures that causes lines to expand beyond the frames. That's one of the reasons why David T added a an 'Illustrations' section to the Technical Forum. No help here of course. The best way to deal with this is to put images in your personal image area and link to them. When I wrote that the text problem was mentioned in Help I was wrong. Memory, eh? Looking through the Help section with my ex-Webmaster's hat half on, it could do with a look at for that reason and following the recent WA upgrade.

    Ah ha!

    I did indeed cut-and-paste from MSWord, but the text was within the lines after I did that.

    But yes, the text grew beyond the lines when I copied the photo in there. I guess I should have posted a link to the photo.

    On another note, when I post on a JRA forum from my iPad I actually have to type blind; the text doesn't appear on my screen until I minimise the keyboard.

    Thanks for the advice Brian, I'll reroute the YHP and see if it becomes unsticky.

    Save me a croissant, I'll be there soon!

    Hi Matt

    Congrats on your first sail.

    The yard hauling parrel should be attached to the yard about half way along, then go round the front of the mast from port to starboard, then back towards where it started from. You need a block - non swivel is fine - at that point to starboard of the line's attachment point. Shove the rope through the block from top to bottom, then take it  down to the deck inside the lazy jacks, then to a swivel block at the bottom starboard side of the mast then back to the cockpit. If it's sticky round the mast, check the routing and then try a a more slippery rope.

    Re the sheetlets, you perhaps need to extend the second batten backwards so that you can start the sheet there. This will give you control of the second batten. The first batten isn't usually sheeted. If you're ever reefed down to one panel the boom and other battens take the strain.

    Incidentally your text spills outside the right hand side of the frame on my laptop. Perhaps you pasted in from Word. It's best to paste from a text editor such as Notepad. I'm going to do that now - fingers crossed. This is mentioned on our Help page. [Later edit: no it isn't. See my later post.]

    All the best Mr Junkie and hope to see you in Brest the second week of June. Chris Gallienne is hoping to turn up, and Paul Fay will already be up one of the rivers, and Maddy and I will be in Marina du Chateau with Paradox. So this will be the first French junket. Of course you knew all that because we're in touch by email. I just thought I'd mention it for the benefit of anyone else who is crossing the Channel soon too. For the record it's not an official JRA event and isn't organised by the JRA. It's just a few members doing their thing. Our Sailing Secretary Ash plans to email French members soon. Best wishes.

    Just got back from our first sail aboard Mariposa; a quick potter around Plymouth Sound.

    We motored out of the marina two hours before high tide, through a misty drizzle, with a scant 10cm of water under the keel. We didn’t run aground, we got out, then back in two hours later, without running into the mud.

    We motored out into a broader and deeper patch of water, where we had enough room to drift while I faffed about with the brightly coloured lengths of string.

    There was a light westerly breeze, about eight knots, and the sail went up as I hauled on the halyard, only occasionally having to untangle the mainsheet.

    And, well, we sailed! It was simple and trouble free; the boat heeled to the wind only about ten degrees, we were able to go about fifty degrees off the wind, and moved at about three knots. Being cautious, I only hoisted five of the available seven panels.

    Three knots was plenty of speed for a first sail. I turned the motor off, lifted it out of the water.

    Lovely. We sailed back and forth in a straight line five times, just getting the hang of things, and fiddling with the mysterious strings. Pinching up and bearing away, just to see what happened.

    Nine am rolled around, so I dropped the sail and motored back to the marina, and let the dog out of the cabin. Lulu prefers to be in the cockpit, but I wanted an uncluttered cockpit while I clambered about. As I get more familiar I’ll be able to have her with me in the cockpit.

    It was a great win and a milestone; my first solo sail in a junk rigged boat.

    May there be many more.


    A few questions for my JR brethren, and sisteren. I’m jusat going to write down my experience and observations, please chime in with tips and advice for this newbie:

    I think my yard hauling parrel may be mis-routed, or perhaps just needs to be a more slippery rope. It gets in the way, under parrels, and restricts the raising of the sail. I had to go forward to untangle it. Then, once the sail was up, I pulled on the YHP and it wouldn’t move, it was just too ‘sticky’ in its loop around the mast.

    As far as I can tell it is routed as per PJR.

    The luff hauling parrel seemed to work okay, and when I tightened it we seemed to be able to go closer to the wind. With the LHP slack I found I couldn’t go closer than about 80 degrees to the wind, without losing way, but then the breeze was light.

    With the LHP tight, we seemed to get about 50 degrees on each tack, slightly better on the port tack than the starboard.

    I have no sheets running to the top two battens, and the sail did like to get a good twist going. I yanked and fiddled with the sheets, but the sheeting arrangement seems to allow the higher battens to fall to leeward, with a subsequent tightening of the lower sheet spans.
