I have just returned from sailing 2000 miles on a Swan 48 (it’s a hard life) and was amazed to see that the mainsheet only had 2 falls between the traveller and the boom.
On my B34 there are 3 blocks on the underside of the boom and a total of 5 falls, which makes the boom difficult to run out in light airs.
I am minded to change the arrangement by removing one of the blocks and reducing to 3 falls, which would make the mainsheet heavier to handle but it should be much better in lighter airs.
Has anyone tried this or can anyone see a problem before i have a go.
The pulleys supplied with the boat tend to have a bit of friction. You could try chaning them for roller bearing pulleys – sometimes said to be suitable for racing. This reduces the friction a lot and should free the mainsheet. If you lubricate them use very light oil only.
