Performance
A satisfying, safe, economical and environmentally responsible explorer yacht must perform well over a range of wind-conditions and directions to
- allow for fast passages
- minimize motoring and fuel consumption
- be safe in heavy weather and challenging conditions.
Moving at a whisper and achieving dramatic top speeds is not important.
goal | satisfying | safe | economical | environmentally responsible |
minimized rather than no engine use | the best moment is when the wind fills the sails and the engine is cut | reduces fuel consumption | avoids emissions | |
high average speed | fast passages | easier to avoid heavy weather | makes long passages economically and environmentally feasible | |
pointing well | better Speed over Ground (SoG) -> less motoring | easier to avoid lee shores | reduces fuel consumption, faster passages | avoids emissions |
highly efficient under engine | allows long motoring when advisable | saves fuel | reduces emissions |
With decades of experience with off-shore racing and designing fast and successful off-shore racing boats, Owen-Clarke Design were in an ideal position to design and optimize Lynx.

Using VPP, various combinations of hull-shape, reinforcements and rigging were analyzed for a 6350 miles course from Western Europe to Montevideo using 3 years of November wind data.
As the results show, this passage could be done very fast with a minimum time motoring.
Passage Time | 30 days 15 hours 15 minutes | (735.5 hours) |
Average Boat Speed | 8.64 Kts | |
Average Daily Run | >200 NM | |
Time under engine | 21.3 hours | 2.9% |
Sail and Motor Usage
Sail | Hours | % |
J2 | 58.8 | 8.0 |
J3 | 0.1 | 0.0 |
C0 | 135.6 | 18.4 |
A3 | 202.3 | 27.5 |
A2 | 317.2 | 43.1 |
Engine | 21.3 | 2.9 |
Considering the efficiency of the engines, fuel burn would be very modest:
Assuming two hours per day of engine use total and a fuel consumption of 3l/hr for propulsion/power generation/watermaking and 2l/hr for power generation/watermaking and 1.5 l for power generation only, estimated fuel burn is as follows:
Propulsion | Power Generation | Water- making | Fuel (l/h) | Hours | fuel burn (l) | |
✔ | ✔ | ✔ | 3 | 21.5 | 64.5 | |
✔ | ✔ | 2 | 23.5 | 47.0 | ||
✔ | 1.5 | 15.0 | 22.5 | |||
total (passage) | 60.0 | 134.0 |
