The Somo 23 is a 7.01 m displacement racing yacht designed by Roca and built by TAYLOR, first launched in 1977. It races in Sportboat. Across the measured fleet it goes better than its own numbers promise, ahead of 7% of the designs it races against.
Goes better than its own measurements promise, and does it better than 7% of the boats it races against.
26th of 28 in its class.
Updated — First Race Edge for this design. Enough boats of this design have now been measured to rank it.

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.
This design is even-tempered. It rewards preparation and crew work more than it rewards picking the right day.
Where it gains
Its best ground is across the wind when it blows, where it outruns what it looks like on paper.
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.
Full width is 0.4 kn either way.
At 10 knots the boat and its rating are in balance across the course.

Rigging
Somo 23 rig and sail dimensions
A Somo 23 carries 7.94 m of mainsail hoist on a 2.25 m boom, a forestay 7.34 m above the deck. Typical figures across the 8 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 24 to 33 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.
