The New York chapter of the American Institute of Architects came up with a high-minded solution to the problem a couple of years ago: a round-the-island architectural cruise with running commentary provided by experts.

On most cruises young docents provide the oral annotation, but every few weeks a guest expert takes the mike. For this Sunday’s Around Manhattan cruise, the organization has booked John Hill, the author of “Guide to Contemporary New York City Architecture” and the Daily Dose of Architecture blog.

The cruises set sail from Chelsea Piers; 2 hours and 45 minutes later, after a 32-mile journey past 156 sites indicated by tiny photographs on a handy brochure, the Classic Harbor Line yacht returns and disgorges its information-stuffed passengers.

It’s an eye-opening experience.
