    I have come accross a lone block (single) aft from the jib fairlead, located just below gunwhale height.

    I am surmising this is optional, and used for the spinnaker ?? The other side has the ring, but no block.

    Currently no sheets run through this, so I am as a novice somewhat at a loss to the function. I have checked the 3rd edition Wayfarer book I have but cannot make sense of it.

    It could be perhaps some adjustment to the spinnaker guy and sheet, but I am not sure.

    Does anybody know what I am describing here ? I will be away for a while, but when I am back I can post photo’s.

    Wayfarer in question is a +S.

    Many thanks,
    Boris, the puzzled.

    I’m a bit confused about the location of your mystery block – is it on top of the deck? Also, is it screwed down flat, flush mounted, on a swivel etc?

    The general arrangement for spinnaker sheet / guy is for one continuous sheet that goes from clew of the sail to a turning block mounted fairly well aft on the deck, say a foot forward of the transom. From here it then leads forward (either under or above the deck) to a further turning block about where the crew sits, then across the boat and back via the same route on the other side of the deck and finally back to the other clew of the sail.

    Your block could perhaps be the second block mentioned above?

    That takes care of the sheeting aspect, but a further complication is added as each sheet doubles as a guy when it is on the windward side of the boat. For this there needs to be some means of temporarily rigging the sheet direct from the clew of the sail to somewhere around about the windward shroud. The two usual solutions are either a clam cleat with a combined hook on the side deck, so the sheet can be hooked under it and cleated, or else the sheet is rigged through an eye which is thence rigged to a barber hauler at about shroud location. This can then be pulled tight to pull the weather guy down to deck level while the leeward one is always released to allow the sheet to lead direct to the normal block at the aft deck.

    Both systems have pros and cons. The “simple” cleat arrangement is easy and uncluttered, but can be tricky for gybing in strong winds. The barber hauler makes that easier but clutters the boat up with more rope, and the weight of the string hanging on the (leeward) sheet can make it harder to get the sail to set in light airs.

    I sail on a lake where we get more than our fair share of light variable winds so I tend to favour the simple cleat arrangement; if I sailed on the sea I’d probably prefer the barber hauler idea.

    Can you say what size the block is,what size rope do you think it is for??

    If it is bolted to the virtical part of the side deck and it will take an 6/8/10 mm rope through it it could be for a jib sheeting system that used to include a mainsheet jammer on the thwart.
    The sheet went through a pully on a track,up to the said block and then down to the jammer on the thwart.

    This could have been taken off,a track and cleat system put on and the block left as it was bolted to the boat and not easy to remove.

    Thats one idea!!!

    thank you gentlemen, I think a photo is needed. Will try and get one this week/end.

    Apologies for the delay, just back from (non-sailing 🙁 ) holidays
