Adjustable back stay
This is surprisingly simple to fit and yet impressively effective.  An adjustable back stay allows Pat to flatten off the mainsail and increase forestay tension while heading upwind. Allowing better pointing and a powerful method of depowering the full mainsail in gusty conditions.

The Evolution Effect – Jester

Rigging is so much more to us at Evolution than just hanging around up masts.  In this new series we take a look at projects where we’ve helped different owners adapt and evolve sailing systems to make the most of their time on the water.

Boat: 2010 Dufour 32 “Jester”
Owner: Pat York

Mission: To make cockpit layout more ergonomic for inshore club racing

The Dufour 32 is a great yacht for "around the cans" club racing, it's small enough to be manoeuvrable, but big enough not to make every beat seem like a slog across the North Sea. Pat has enjoyed some successful racing with Jester but was finding the lack of space in the cockpit could sometimes turn mark roundings into an onboard "bun fight". He came to Evolution looking for a solution. 

Move the mainsheet traveller back in the cockpit  
By moving the traveller to the middle of the cockpit we created space for headsail trimmers to access the primary winches without getting wrapped up in the mainsheet. Meanwhile the mainsheet trimmer moves back in the cockpit and is able to communicate directly with Pat while he’s steering. If sailing short handed Pat can easily manage the mainsheet from his helming position while still watching what’s going on outside the boat.

Dyneema halyards
Pat had been racing using his standard supplied braid on braid halyards to the best of his ability. These braid lines are strong enough for general purpose use but to gain the extra % in racing terms he was introduced to the wonders of Dyneema. The very low stretch properties of Dyneema gives the advantage of minimising the amount of sail power lost when converting wind power to forward motion together with being 3-4 times as strong as braid so the diameter of line can be reduced .  

Science bit.

Dyneema = Ultra high molecular weight polyethyline
Pound for pound dyneema is stronger than steel.
Stretch < 1.5%
Doesn’t absorb water
UV stable 



The harmonious result
The combination of moving the traveller and making more usable sail controls has not only given Jesters trimmers much wider scope to get the most out of her sails but also made the cockpit a more harmonious place to be.
