Updated

The IMX 38 is a 11.36 m displacement racing yacht designed by Niels Jeppesen and built by X-Yachts, first launched in 1992. It races in Class C. Across the measured fleet it goes better than its own numbers promise, ahead of 67% 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.

Sharper round the buoys. Short courses reward acceleration and manoeuvring, and that is where this design makes its money.

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 does most things without giving much away. It rewards preparation and crew work more than it rewards picking the right day.

Where it gains

Its best ground is on the beat in the light stuff, where it does more than its size and sail area promise, and by a margin worth having. It holds that advantage off the wind as well, so the gain is not down to one leg of the course.

Where it pays

There is no condition where it falls away badly, which is worth something over a season of mixed weather.

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.

Rigging

IMX 38 rig and sail dimensions

A IMX 38 carries 13.34 m of mainsail hoist on a 4.90 m boom, a forestay 15.49 m above the deck and a 5.09 m bowsprit. Typical figures across the 36 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 81 to 138 m² depending on bowsprit and set-up. Before ordering a sail, read the figure on your own measurement record rather than the typical one for the design.
