the center's best known feature is the sails pavilion. it is a exhibit and special event area. the sails pavilion's roof includes teflon-coated fiberglass "sails". they are intended to show san diego's maritime history. the pavilion was first built as an open-air facility under the roof. this made it hard to get people to use it. because of this, the pavilion area was enclosed in glass. this made it much more usable.
