I just bought a Beneteau 423. It has 2 halyards installed - one for the foresail and one for the mainsail. It looks like there are openings on the mast for 2 more halyards. I'd like to install at least one more so I'll have a spare for a stormsail or for when I go up the mast. How do I run it up/down the mast without getting tangled up inside?
