ISSA · Sam Manuard · 2012
Updated
The Seascape 27 is a 7.99 m planing racing yacht designed by Sam Manuard and built by ISSA, first launched in 2012. It races in Sportboat. Across the measured fleet it goes better than its own numbers promise, ahead of 81% of the designs it races against.
Goes better than its own measurements promise, and does it better than 81% of the boats it races against.
6th of 28 in its class.
Not verified. On planing hulls this score has no match in the race results we hold: designs scoring the same win anywhere from one race in ten to seven in ten. Read it as what the measurements say, not as a ranking.
This design has been found in real race results — 6 starts across 5 events — not only in measurement files.

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.
The stronger it blows, the better this design looks. Give it a fresh day and long legs and it delivers more than it promised; in a drifter it is working uphill.
Where it gains
Its best ground is on a broad reach when it blows, where it goes better than its measurements say it should, and by a margin worth having. It holds that advantage running deep as well, so the gain is not down to one leg of the course.
Where it pays
It falls short to windward in a strong breeze, giving away time it never gets back. That is a hull that wants to get up and go, and needs pressure to do it.
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 2.8 kn either way.
At 10 knots this design makes back more than its rating asks on the broad reach.

How they are set up
The range each sail spans across the fleet.
Most run a fixed propeller. A bowsprit is standard across the fleet. Crew weight is declared around 350 kg.
Rigging
Seascape 27 rig and sail dimensions
A Seascape 27 carries 10.02 m of mainsail hoist on a 3.55 m boom, a forestay 9.71 m above the deck and a 5.23 m bowsprit. Typical figures across the 14 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 65 to 79 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.
