Rigging & sails

Stepping the mast single-handed

The deck-stepped alloy spar is light enough for one person with an A-frame and a plan, and dangerous for one person without either.

The mast is deck-stepped with single swept-back spreaders, which is exactly the arrangement that lets one person raise it — the swept spreaders hold the spar in line while it goes up.

Setting up

Pin the mast foot first and let the spar lie aft along the boom gallows. Both lowers stay connected the whole time: they are what stops the mast falling sideways at the halfway point, which is the only moment that really matters.

Raising

Take the load through the A-frame and the trailer winch rather than your back. Slow and continuous beats strong and jerky, and lets you stop and look.

Tip: tape every split pin before the mast goes up, not after. Doing it at deck level takes a minute; doing it at the hounds takes a ladder.

Tuning afterwards

A fractional rig wants the forestay tension set with the backstay, not the shrouds. Get the mast in column first with the lowers, then add rake.
