Holland America easily has the industry's most comprehensive online boutique, but it sells so much stuff -- and so much that's unrelated to Holland America -- that it's tough to wade through. If you've got the patience, really interesting finds include art nouveau posters of a couple of ships ($175), a copy of "The Captain's Log" by HAL commander Captain Hans Mateboer ($14.95) and Mariner Dream Beds from $999. Otherwise, you can find books by Jonathan Raban and John McPhee, travel guides by Fodor's and Riedel wine glasses, with far less hassle than at major Web sites.
