What's the primary reason the F17 is 15.5 minutes faster around the buoys than a NACRA 4.5 in 100 minute race?

1. Waterline length
2. Only 15% heavier with both having one crew, but spinnaker makes up for it
3. Much faster to tack due to daggerboards
4. Dagger boards allow it to point higher
5. Higher aspect ratio sail

What time is it?

half past twelve

Whats the capital of France?

Clearly the F17 has an advantage only being 1.56kg
