Most serious cruisers have migrated off of newsgroups and onto
moderated web based forums. That is regrettable in my opinion but
you can't fight city hall. That said, let's start a thread here
listing some of the better cruising web sites.

I'll start with some that I've found:

http://groups.yahoo.com/group/Cruisers_Network_Online/

http://www.cruisersforum.com/

http://cruisersnet.net/

http://www.trawlercrawler.net/

http://ssca.org/cgi-bin/pagegen.pl?pg=home&title=Home
(membership required)

http://www.noonsite.com/

http://www.mtoa.net/

https://activecaptain.com/
(Interactive Cruising Guide Book - good online charts and local
knowledge)

A word to the wise: None of these groups tolerate asshats, personal
insults or political discussion. Don't even think about it.
