These 1-hour or 2-hour narrated tours lead passengers through the San Diego harbor on one of eight different yachts, ranging from a 61-passenger antique yacht to a three-deck, 800-passenger behemoth. You'll see the Star of India, cruise under the San Diego-Coronado Bridge, and swing by a submarine base and an aircraft carrier or two. Guests can visit the captain's wheelhouse for a photo op, and harbor seals and sea lions on buoys are a regular sighting. Whale-watching trips (mid-Dec to late Mar) are a blast, a 2-hour weekend champagne brunch cruise departs at 11am, and dinner/dance cruises run nightly.
