Double-ending jib halyard

[Brion Toss]

Hello,
As Brian notes, you could keep the 2:1, but don't make it double-ended; you'd just be multiplying weight, windage, and cost. Besides, you can have a belay at the mast as well as the cockpit: get a stopper with the option for the clutch staying open when the handle is closed (Spinlock has a nice one). When you hoist at the mast, you disable this feature, and it works like a regular clutch. When you are planning to work from the cockpit, you activate it, and the line runs through unimpeded.
Also consider that, as long as you have winches fore and aft, you likely don't need a 2:1 purchase on this boat.
Fair leads,
Brion Toss
