In stormy weather, when your 2nd or 3rd reef of the mainsail just isn’t enough, the way to go is with a trysail.

A trysail is a loose-footed, fairly flat sail made from heavy sailcloth, but with a luff length and foot length considerably shorter than your regular mainsail. It is hoisted on a separate track, independent of the normal luff groove.  

The trysail track is fitted beside the luff groove on the aft side of the mast and runs all the way to deck level. That way you can always have your trysail fitted to the track, ready to be used.

When using a trysail, the end of the main boom is secured to the deck. Sheeting point should be according to the illustration. If trysail luff length is not available from the yacht designer, our  general recommendation is that the trysail should reach 55-65% of the foretri angle height.

The track should end approximately 0.5 m below checkstays/ runner attachments, if any. 

We recommend fitting three sliders at the head and tack of the sail  (c/c 50 mm), remaining sliders to be fitted c/c 400 mm. Silicone lubricant can be used on the track to minimise friction.
