How to estimate it

Fermi’s official “Napkin math”

The Atlantic from the Canary Islands to the Caribbean is about 3,000 miles. How fast does the best sculler on Earth go? Quicker than it looks, about like a steady bike ride. Call it 10 miles an hour.

Canaries to Antigua
~3,000 mi
Olympic sculling speed
÷ 10 mph
3,000 ÷ 10
≈ 300 hours
÷ 24
≈ 12.5 days

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.

Source calculation & reference
Paris 2024 gold, Oliver Zeidler, 2,000 m
6:37.57
Speed
≈ 18.1 km/h (11.3 mph)
Race course, La Gomera to Antigua
≈ 4,800 km (3,000 miles)
4,800 ÷ 18.1 = 265 hours
≈ 11 days
