Halyards and fairleads on the same side

    Today I put the main up and took the fore down. I took some pictures which I uploaded to my album which show the fore cap and fairlead bracket. For some reason they are upside down, sorry but I have limited bandwidth and will have to fix that problem when I have a better internet connection, but the caps are clearly shown. I'll have another look and consider the chain solution. I have materials to make a bolt-on crane, that would be more work but I do want to get it right.

    OK, Robert,
    since your mast cap is of the PJR type, and I happen to have Malena’s PJR style mast cap right by my side here: Imagine we look at the cap from above and use clock analogy for orientation, 12 o’clock being forward.

    I suppose you then have a tang in the 5 o’clock position, but wish you had it at 7 o’clock instead (..or vice versa...). If I were in your position, I would shackle a piece of chain from that 5 o’clock tang to the one which hopefully sits at 9 o’clock. This chain should be slack enough to make almost a half-circle bight when unloaded.

    The new halyard block can then be clipped to the chain in the position you want.

    Arne

    PS: If you are to use a 5-part halyard, I suggest you use both the 5 and 7 o’clock tangs, the way I did on Johanna’ sail. That gives better lead for the fall and better resistance against twist.

    At the moment the foremast is up and the mainmast is down, I'm putting the main up and lowering the foremast today so I can get a picture of the foremast cap later. The mainmast is the only one that is ok, because I put cranes on both sides. I thought some day I might want to put all 3 sails on the same side, so on the main I put cranes and fairleads on both sides. Wish I had done that on all 3.

    After more consideration I've decided I don't need to change the mizzen cap, it will be easy to install eye bolts for fairleads on the other side and leave the crane as is. I'll only need to make one bolt-on crane so that makes my blunder only half as bad as I first thought.

    I do like having the masts in tabernacles, raising and lowering them has turned out to be quite easy. I did it that way out of necessity because this boat wasn't designed for a 3 masted rig and keel stepping them wasn't possible, but if the tabernacles prove themselves by holding up over time, I think they will be well worth the extra work.

    Robert, could you show us a photo or diagram of the mastcap? Are you using a 3-, 4- or 5-part halyard?

    Sounds as though modifying the mast caps is the least-worst solution then.  What a tedious and time-consuming nuisance.  However, from the pictures in your profile, you are obviously very skilled at this sort of metalwork, and, of course, you can congratulate yourself on having had the foresight to step your masts in tabernacles...

    The problem is that I welded lugs for fairleads onto the tabernacle. I could move those, but that would be even more trouble. The galvanizing would have to be ground off and repaired. I need to have the foresail and main on opposite sides, or else all the running rigging would be on the same side. I can make new cranes to bolt onto the mast caps, just wish there had been a junkie around to point out my blunder before I installed them.

    Another thing I'm not clear on is how to run the halyard without it getting pinched between mast and sail.

    Seems too easy, but could you not have your sails on the starboard side of the masts?

    I suspect you could end up with chafe problems and also jamming of the halyard etc. between the sail, spars and mast. Generally all the running rigging should lie within the 'chimney' on the side of the mast opposite to where the sail sits. This allows all lines to operate freely in an area where the sail never rotates. 

    What a nuisance discovering this problem when you are so close to finishing!

    My conversion project is in the final stages, and I hope to be back in the water and trying it out in February. However, I recently discovered that I made a mistake when I made the mast caps and fairleads, I put them on the same side, which looked right, but then realized that the running rigging should be on the side opposite the sails. My mast caps are similar to the ones illustrated in PJR, with cranes at about 45 degrees from the aft sides.

    This is probably a foolish question, but I'm wondering if it's possible to have the halyard, thp etc. on the same side as the sail? I already got materials to make cranes on the opposite sides, but the trouble is that the caps are stuck on with marine sealant and I doubt if I could get them off without a lot of damage. I'm planning to make the new ones to fasten on with bolts and screws, but then thought it might be wise to seek some junk wisdom on this site before going through all that trouble.

    I lent my copy of PJR to the sailmaker so I'm completely without guidance at the moment.
