Guys
I found this site recently and thought it may be of interest to you.
http://www.rina.org.uk/index.htmlIf you go to publications you can view or download lots of very interesting magazines and articles.
Specifically in Journals, you have Ship and Boat international, The Naval Architect, Ship repair and conversion Technology and Offshore Marine Technology amongst others. (Lots on new boats,tugs and ships.)
Some of these you can download all of the 2008 releases.
Best wishes
