Schock 35

SCHOCK · Shad Turner · 1984

Updated

The Schock 35 is a 10.76 m displacement racing yacht designed by Shad Turner and built by SCHOCK, first launched in 1984. It races in Class C. Across the measured fleet it goes better than its own numbers promise, ahead of 59% 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.

There is no obvious weak spot here. 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 in a strong breeze, where it goes better than its measurements say it should, and by a margin worth having. It holds that advantage to windward as well, so the gain is not down to one leg of the course.

Where it pays

It falls short off the wind in a working breeze, giving away time it never gets back.

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

Schock 35 rig and sail dimensions

A Schock 35 carries 13.41 m of mainsail hoist on a 4.21 m boom, a forestay 14.96 m above the deck and a 4.21 m bowsprit. Typical figures across the 8 boats measured under the current VPP, with the range each one spans.
