Sail plans built
for the boat
in front of you.
From a 1929 ocean-racing yawl to a 72-foot foiling catamaran, Kevin turns design intent, rating targets and real-world sailing demands into a working inventory.

A classic rig, rebuilt for blue water
Dorade
Kevin led sail planning and design for Dorade, while serving the campaign as tactician and sailing master.
The assignment was unusually exacting: preserve the identity of Olin Stephens’ 1929 yawl while giving her the range to race across oceans and the precision to win modern classic regattas. Kevin’s work connected sail selection, rating optimization, boat development and how the crew would actually use the inventory.
Dorade’s results belong to the full campaign team. This showcase focuses on Kevin’s sail-planning, development and sailing contribution.

Transpac
1st overall · corrected timeThe first major test of the Return to Blue Water campaign ended with the 1929 yawl winning the 2,225-nautical-mile race on corrected time. The result showed that a historically faithful rig could still carry a genuinely competitive offshore inventory.

Persico Cat 72 · 2025
Extreme H₂O
2.0
A sail plan for a foiling 72-footer has to work as part of one system: aerodynamic load, foil balance, flight control, a small crew and a speed range that changes apparent wind quickly. Kevin translated those demands into the boat’s working sail program.
The platform
High-modulus carbon, rake-controlled foils and a three-person sailing station—built to fly fast and still cruise intelligently.
- Stated top speed
- 40 knots downwind
- Upwind capability
- Up to 26 knots
- Righting-moment foils
- More than 7 meters
- Operational crew
- Three sailors
- Auxiliary power
- Electric · zero-emission operation
Performance and system figures are stated by Persico Marine for the Cat 72 program.

An earlier chapter
Extreme H₂O
Before the Cat 72 came Pat Benz’s bright-green Gunboat 66—and a first-to-finish multihull result in the 2015 Transpac.
Kevin raced the Los Angeles-to-Honolulu course aboard the original Extreme H₂O. The boat took the Rudy Choy Trophy for first multihull elapsed time and finished second in ORCA on corrected time.

Sail inventory & optimization
Westerly
A classic Santa Cruz 52 made competitive for a new chapter.
Within a wider optimization effort that included keel and transom-scoop work, Kevin designed and built Westerly’s complete sail inventory at North Sails Channel Islands. The program used the 2023 Newport to Cabo race as a benchmark on the way to Transpac.
“The importance of excellent sails cannot be overstated.”— Dave Moore, Westerly
