Hello all. I’d be very grateful indeed for any advice the members could give me regarding the best set up of a centre mainsheet on a GP14. My friend and I have bought a 1993 Duffin-built wooden GP14, sail number 13225. She is in good condition after some minor repairs over the winter. When looking into how to set up the centre main, almost all the examples and guidance online appear to show the mainsheet running up from a block fastened to the centre of the deck (which is present on our GP) to a single block fastened at the centre of the boom, and then running out to another single block at the aft end of the boom, from where it extends down until it meets a block fastened to a rope traveller extending over the width of the transom and then back up to an anchoring point. My question is this. Is this set up simply due to convention i.e. it’s done this way because it’s always been done this way, or is it seen as being the best set up for a dinghy of the GP14’s design? The reason for the question is that we are considering whether there is any merit in setting up the centre main so that it takes a couple of runs from a double sheave block up to another double sheave block under the centre of the boom and back down again, with no extension out to a transom traveller and aft anchor point. It’s a set up similar to one which you would see on, for example, a Laser Bahai. Is this is a good idea? Are there any arguments against it? Many thanks in advance for any advice.</p>
