The Great Divider from Patagonia has moveable, rigid-foam, hook-and-loop-equipped dividers that split its 1,400-cubic-inch interior space into useful compartments. Made from sturdy waterproof 840-denier nylon double-coated with polyurethane film, the bag has a highly water-resistant zipper, a molded bottom that is tacky enough to stay put on a wet deck and clear, zippered interior pockets that betray their contents at a glance. The Great Divider comes with a detachable shoulder strap and sells for $165. Patagonia; (800) 638-6464; www.patagonia.com.
