Monday, May 26 (Memorial Day), USS Pampanito hosts the annual Lost Boat Ceremony aboard the WWII-era submarine docked at Pier 45, Fisherman's Wharf. The ceremony honors submariners killed in action — specifically those lost on boats that never returned. Admission to the ceremony is included with regular museum entry: $20 adults, $10 kids 6–12, free under 6. No BART direct to Pier 45; take the F-Market streetcar to the Fisherman's Wharf stop. No age restriction, but the interior submarine passageways are tight and not stroller-accessible.

The Pampanito herself is the draw here — a Balao-class fleet submarine that ran six war patrols in the Pacific, sank six Japanese ships, and rescued 73 Allied POWs in 1944. The Lost Boat Ceremony is a specific naval tradition: boats that went on eternal patrol are called out by name, and a bell is rung. It's brief, spare, and not theatrical — which is what makes it land. This isn't a general veterans event; it's submarine-specific, and the people who show up tend to know why they're there.

Practical note: Pier 45 parking is expensive and fills early on holiday weekends. The Ghirardelli Square garage on North Point is a shorter walk than it looks and usually has space by mid-morning. If you've got two hours, do the ceremony first, then walk the topside deck before the tour groups hit. The forward torpedo room is worth the crouch.
