Best 24 h: 38 nm Sailing Ursa
Ursa is a Valiant 40 cutter, purchased in 2017 in Ventura, California. After a shakedown across the Channel Islands she sailed south — San Diego, Pacific Mexico, and years exploring the Sea of Cortez.
She is now deep in the South Atlantic, partway through a floating refit and bound for the Patagonian fjords.
