Single Line Preventer Set-up
A line is being led via a clutch in the cockpit and via blocks to the mast and up to the gooseneck of the
boom. From there it will run along the boom to a block attached to the end of the boom and back to the preventer attachment at the boom - clipped in via a snap shackle - ready for deployment. (see Single Line Preventer drawing)
Advantage: This set-up provides you with an easy way of just opening the clutch in the cockpit and somebody to walk forward taking the snap shackle off the vang attachment and pulling it forward to a strong point ahead of the mast. Even with the boom right out over the lee side of the boat, the snap shackle on the boom vang attachment should still be within easy reach.
Disadvantage: When gybing, you will have to move the line around the mainsheet tackle to the other side. Again, this can be a bit difficult depending on how far back on the boom the mainsheet blocks are situated. It also presents itself as a single solution only to preventing. And as we all know, the best set-ups on a boat are the ones which have more than one use only.
