Updated

The Esse 750 is a 7.50 m planing racing yacht designed by Umberto Felci and built by Proteus Yachts, first launched in 2011. It races in Sportboat. Across the measured fleet it goes better than its own numbers promise, ahead of 96% of the designs it races against. It is at its best in light air and struggles to hold that once it blows.

Round the buoys, or offshore

A short windward-leeward and a night at sea ask different things of a boat. Here is how this one does in each.

Speed in knots at 20 knots of true wind. Green marks the angles that pay: the closest useful beat and the deepest run worth sailing.

Where it wins and where it pays

Every boat is judged against its own measurements — length, weight, sail area. The quicker those say it should be, the more it has to deliver just to break even. Going fast is not enough: it has to go faster than its own numbers promised.

It needs pressure to show what it can do. On a windy coastal course it is in its element; on a light-air windward-leeward it has to be sailed well to hold on.

Where it gains

Its best ground is running deep in a strong breeze, where it outruns what it looks like on paper, and by a margin worth having. It holds that advantage on a broad reach as well, so the gain is not down to one leg of the course.

Where it pays

It falls short on the beat once it pipes up, giving away time it never gets back. That is a hull that wants to get up and go, and needs pressure to do it.

Above the line it delivers more than promised and gains on the fleet. Below, it falls short. Move the wind: plenty of boats sit on one side in the light and the other when it blows.
