CB · Carl Beyer · 1999
Updated
The Cb 365 is a 11.06 m semi-displacement racing yacht designed by Carl Beyer and built by CB, first launched in 1999. It races in Class B. Across the measured fleet it goes better than its own numbers promise, ahead of 31% of the designs it races against.
Goes better than its own measurements promise, and does it better than 31% of the boats it races against.
64th of 92 in its class.
Updated — First Race Edge for this design. Enough boats of this design have now been measured to rank it.
This design has been found in real race results — 1 start across 1 event — not only in measurement files.

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

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 a broad reach when it blows, where it does more than its size and sail area promise, and by a margin worth having. It holds that advantage on the run 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.
Full width is 0.4 kn either way.
At 10 knots this design makes back more than its rating asks on the beam reach.

How they are set up
The range each sail spans across the fleet.
Nearly all carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 730 kg.
Rigging
Cb 365 rig and sail dimensions
A Cb 365 carries 13.63 m of mainsail hoist on a 4.78 m boom, a forestay 14.70 m above the deck and a 4.81 m bowsprit. Typical figures across the 4 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 77 to 101 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.
