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.

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 is an upwind boat first. Windward-leeward courses give it more of what it is good at than a coastal race does.

Where it gains

Its best ground is upwind when the breeze is soft, where it outruns what it looks like on paper, and by a margin worth having.

Where it pays

It falls short across the wind when it blows, giving away time it never gets back. That is weight that has to be driven rather than released.

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

Olson 911 rig and sail dimensions

A Olson 911 carries 10.82 m of mainsail hoist on a 3.64 m boom, a forestay 12.59 m above the deck and a 3.70 m bowsprit. Typical figures across the 5 boats measured under the current VPP, with the range each one spans.

The spinnaker spreads widest of all — 65 to 71 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.
