The Chair of Naval Heritage and History has developed some resources 2.0 with the aim of bringing to the public the Naval and Maritime Heritage that we have inherited. With the objective of improve the digital bridges layed, we analyze the records of one of those tools, a blog, and the interaction of the entries with another successful tool, Facebook. For it, with a simple of 250 items, we study some aspects like its thematic category and the number of visits received on the blog, as well as likes, shared publications, and comments obtained, both by the blog entries and its replica in the social net. The results show that the topics more consulted, apart of the generic, are: legends and sailors´ myths and Naval Construction History; in the blog we obtain more visits but more disparate, while in the social network get less but more regular; we obtained more amount of likes in Facebook than in the log book, but in both tools they increase progressively; shared publications grow considerably in the last third of the period; comments are more produced in the blog. Finally, we conclude that we have carried out an efficient managemet of the 2.0 communication tools, but to optimized them we have to polish some aspects for the future.
