If you’re interested in ships, and you’re here in California, check out the Lady Washington, a replica of a late 18th-century ship of the same name. The original Lady Washington was the first ship to round Cape Horn and the first American ship to reach the Pacific Northwest.

The replica ship is in San Francisco through tomorrow. You can even sail with the boat on a bay sail or along certain passages, from SF to Rio Vista in the Delta, for example. When she’s not sailing you can go aboard for a tour and her friendly crew will answer questions. She’s docked at Pier 40.

The ship will be making its way down the coast to San Diego by December and back up the coast to Washington, where she’s based, in 2013.

Here’s the ship’s calendar.
