If you can afford $50 for a subcription to Cruise Industry News Quarterly, this is a first class source on cruise ships covering construction, design, and operation of. This publication is not a travel magazine but is confined to all spects of the cruise industry. For example my Winter 1999/2000 issue covers such items as Safety At Sea; Fire Safety Regulations and Upgrades; Advances in Fire detection; Regulatory Compliance Auditing; Articles on the construction of CelebrityMellenium. I have no association with the publisher.
