Only change I would make is to have the line continuous, meaning less line, as one gives, the other takes away. Also have snap-shackles on the lower ones, so you can move them around for different reasons, like Sailing Downwind (move one forward as preventer) Parties (Clip onto drunk friend and pull out of canal) Get it out of the way at anchor
We have double tailed (single sheet) system on the mainsail
of our monohull
schooner. 6:1 purchase
(line is run: port quarter block-boom block-center block-boom block-center block-boom block-starboard quarter block) 3 sheaves needed on boom, four on deck
and no winch
usually needed on the 630sf large mainsail
(though we have one close to centerline that we could use if we wanted to do so). The outboard
blocks are only about 7 feet apart from each other. Those blocks are snatch blocks and we can leave them on the aft quarters where they are or take them forward to a couple different chain plate
locations if we wanted to prevent. So far we've never moved the snatch blocks forward. The vang action is nice where it is and we've used boom end preventers rigged very far forward rather than carrying the sheet block forward.
Our mainsheet is extra, extra long and that's advisable for using a double tail system. If two sheets
are used, the same would be true. It's nice to have enough line to run your sheets where you'd like. I'm not as nimble as my husband is, and when I'm not feeling all that confident about gusty winds on my solo watches, I've rigged both tails to cleat off near whichever side of the cockpit
I'm favoring (or near the centerline helm
if I'm hand steering).
We have numerous large cleats
around the cockpit combing with jib
, staysail, foresail, and main sheets as the two foresail halyards and gaff vang all led back to the cockpit. We can drop the gaff foresail from the cockpit but not the mainsail --we'd go to the mainmast to do that.
One of the other posters here mentioned rigging
a downhaul on the head/top slide of the mainsail. We do that, but ours is actually just a really long main halyard
-- we take the tail of the halyard
to a slide above the head
of the sail so the halyard makes a loop and you can winch
down on the tail or winch up to raise the sail. If you ever have to reef while on a broad reach or run (e.g. you're in big seas that only a fool would turn up into the wind
to reef in such conditions) likely the only way you'll do it is by cranking down on the head
of the sail using that down haul line. Even the fully loaded sail will come down. It is not fast though and doesn't fit the "dump wind" idea at all.
PS Cavalier --we've dropped the mainsail while running (and reefed there as mentioned) because if you haul a schooner main to centeline that will change your point of sail as the main, in big winds, can overpower the steering
and soon you'd be on a beam reach in potentially very large seas.
Best of luck and sorry for digressing into monohull
schooners but did want to address downhaul and ease of use of double ended sheets.
