Why are the sheets led back to the rear of the cockpit and not to the forward portion?

    Richard, I agree with you that one is never immune against fooled sheets. Still, by designing and rigging in a couple of details, the likelihood of getting in trouble when tacking or (long-) gybing will be much reduced:

    ·         Make and rig the sail with the leech vertical, or even leaning a tiny bit aft.

    ·         Keep the aft batten ends flush with the leech.

    Your method of making the gybes short by pulling in the sheet is of course good, and this also guards against the dreaded fan-ups (with reefed sails in strong winds).

    Cheers, Arne

    My Coromandel, Tammy Norie, has a pretty much textbook HM rig.  You can see the distance and angles between the leech and the sheet blocks in this photo (sail down) and this one (sail up).

    The angle is reasonably generous but the sheets do occasionally foul on a gybe. The spans sometimes get caught under lower batten ends, and sometimes a whole section of the sheet gets caught under the boom.

    My solution is to gybe in a more controlled way taking in the sheet, or hauling the whole sheet bundle back by hand (in light winds).

    So I don't think any angle will make you immune!

    Nope! My boat is Tystie, and I'm now in New Zealand, so no chance of meeting.

    David, what is the name of your boat?  I thought I might like to see a pic in the photo gallery if there is one.  R

    Thank you David for your time spent on my behalf.  I'll give it a go.  Hope to meet you sometime; supper is on me.  My best, Richard

    That's a minimum of ten degrees from the top sheeted batten, which may be about three feet from the clew by the time you get down to the foot of the sail. This is an arbitrary figure; the closer the sheet to the sail, the more the chance of the sheet spans fouling behind the batten ends, but the fouling is just as likely to happen when tacking in light airs, ie, whenever the sheet is slack.

    What you should do is to try a lash-up first, before moving the lower blocks permanently. Just tie the blocks to a point where you think you can make a strong permanent fastening, go sailing in light breezes, and see what happens.

    Thank you David.  If I give the ten percent space as you suggest, and I gybe the boat, might I be in danger of some sort of a tangle with the sheets?  Hence, a minimum of ten percent or more might be required.  Is my thinking correct, or am I just chasing imaginary dragons?

    Again thank you for your help.  Richard

    The sheet needs to make a minimum angle of ten degrees with the leech of the sail, and it sounds as though you can achieve this easily. It's actually counter-productive to set the deck blocks very far aft, as then the sheet tends to haul the sail aft, rather than in, when close hauled. Also, I wouldn't want to have any chance of the mid-air sheet blocks landing heavily on top of the solar panels. I would certainly try sheeting from the forward end of the frame, if the sheet blocks are still below the clew of the sail.

    my pilot cutter (24') on deck has a small cockpit (5'x8') with a stainless steel cage over it.  There is (7') of standing space under the cage which on top is the frame for the solar panels, it extends over the entire (5x8) space. It is a small space complicated by wheel steering in the center of that space.  Not much room to move around in.  From where the bundle ends aft, over the trunk cabin, and passage way to below, to the beginning of the cage there is 3' of distance for and aft.  Is there any reason why the sheets cannot be led down from the sail/battens to the forward end of my cockpit and the lines secured there?  

    There maybe an obvious answer to this but I'm so new at this and I haven't located anyone in the San Francisco California Bay Area that can help me with this.  I appreciate any assistance you might be able to spare.
