30 miles per hour
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Racing catamaran
A Formula 18 racing catamaran at the class limits of 5.52 m length, 2.60 m width and 180 kg minimum ready-to-sail mass, shown at a defined 12 m/s pace. Crew mass and momentary race speed are excluded.

- Comparing
- Speed ↔ Defined fast sailing speed
- Relative size
- 30 miles per hour is larger on this measurement by a factor of about 1.12. 30 miles per hour's selected measurement is approximately 11.8% greater than Racing catamaran's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Racing catamaran uses a 43.2 km/h central value within a recorded range of 7 m/s–64.8 km/h.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
