The Eagle, revenue cutter replica Californian, schooner Lynx and Brando's Bounty are in San Francisco this weekend, near the Ferry Building.
Aside from enjoying the pure beauty of the Eagle, Californian and Lynx (can't say that about Bounty from the gunwale, down), this presents a good opportunity to learn about rigging and its operation from real sailors.
