    Default I don't like the cut of my jib

    It doesn't seem to be the right size for the boat, falling about 3 ft short of the top of the forestay.


    Now I'm not going to get new sails until after I've refurbished her and made sure she stays on the right side of the waterline. In the meantime, would using a line at the tack to raise the jib a couple of feet work for me, or against me?

    Reading suggests that keeping the foot closer to the deck helps to prevent drag from spill-over the foot, but the throat seems too tight at the head unless I ease up on the sheet.

    Yes but you seem to be doing pretty well, single handed against that newer boat with all those hands....

    This was a common sail shape in the 60's and early 70's, often with a hollow leach in the upper portion of the sail. I can offer a few reasons behind the logic, but we've moved past most of this sail design methodology now.

    A newer design sail will set tighter and permit some pointing ability, though your hull also seems to have similar "era" related compromises, which mat negate much of the gains from a new jib cut.

    Can you move the lead block ... the block that holds the genoa sheet to the deck further forward? or are you out of adjustment?

    I think getting the twist of the sail right will improve the ability of the boat a lot and that to get the sail as low as possible is a secondary priority (but still quite useful once the twist is right.).

    I would suggest moving the block forward if you can, or if out of adjustment allow the genoa to go a little bit up the forestay until the amount of twist looks similar to the other boats in the front on pic.

    Also it looks like you could have more tension in the halyard to get rid of the horizontal creases a bit more. You can have the creases when you are trying to get power in light winds but by the time the boat is heeling this much they should start to be quite smoothed out - unless this is a gust on an otherwise light day.

    Best wishes

    By the way .. we do like the "cut of your jib".

    In Reply to: Gimme anwsar----am I being insulted? posted by need answer on April 09, 2001
    : I like the cut of your jibb
    CUT OF HIS JIB - "The cut of a jib, or foresail of a ship indicates her character to a sailor and 'jib' means 'face' in sailor's slang. Thus 'don't like the cut of his jib,' which probably dates to a century ago, translates as 'I'm suspicious of him; I don't like this expression on his face.'" From "Encyclopedia of Word and Phrase Origins" by Robert Hendrickson (Facts on File, New York, 1997).
    Another source, "Salty Dog Talk: The Nautical Origins of Everyday Expressions" by Bill Beavis and Richard G. McCloskey (Sheridan House, Dobbs Ferry, N.Y., 1995. First published in Great Britain, 1983), says the literal meaning of "jib" may be "nose."

    Adjust the block? Not until I rebuild when I shall install this newfangled "block on a track" idea. Until then I'm forced to leave it where it is bolted to a pad on the deck.

    Genie, when purchased, had five bits of rope on her. Two to haul up the sails (canvas ones), one for the mainsheet and two jibsheets.

    I've since built a new boom with outhaul and boomvang, replaced the original 4:1 single ended mainsheet with a double ended clutched version and modified the original sheet horse to work as a traveller. The main now has a leach-cord and battens and needs only a cunningham to finish. So now it's onto the jib. I'll try raising it anyway and see what happens.

    So far the mods all work well. I've gone from tail-end charley to actually winning some (although I only managed second last weekend to somedarn cat). I still think I can get more out of the old girl though

    Oh and those creases have been pointed out to the scurvy dog responsible (I'm not really single-handed.. he was setting the jib at the time) and his back is almost healed and ready for this weekend's racing.

    The boat with all the hands was leading the division ahead of me, sailing a longer course, and I'd just completed tacking to avoid him coming through on starboard for the mark. The boat behind me was my direct compeititor and managed to squeek in for the win when I was forced over... it was a bloody ripper of a race

    and the scurvy dog needs a handle for the halyard winch. The luff needs a lot more tension to pull the draught forward which in turn will allow you to put more tension on the sheet and point higher.

    As Mik says play with the sheeting angle to improve the twist, raising the foot position up the forestay will achieve the same thing so experiment with a line on the tack as you say or alternatively I have used a length of chain for cheap easy adjustment.
    I think 2 feet would be way too much, start small a few inches and work your way up so to speak .

    If that doesn't work to well and the jib looks too high (looks are important too ) fit a kicker arrangement (a block or ring on the sheet via a line through a deck mounted block back to a winch) this works well in light air.

    Nice looking boat BTW

    Good point Mike. Actually he needs to put on more weight, since we both hang off the halyard to set it and I wish to retain my boyish good looks.

    Nice looking boat BTW
    Thanks, she's my first - and I love her (much to the cook's disgust).
