I've subscribed to Cruising World, Sail, and Lats&Atts at different times over the years. L&A was a favorite way back but has become more advertising driven and is now closer to the rest. Both CW and Sail have good articles with practicle application. CW doesn't seem to discount thier subscriptions much, but with Sail if you hold off on renewing they will keep sending you discounted reminders at lower and lower subcription rates. I hold off until it's around $10 for the year!
But now all my subscriptions are expired and it's nearly time to fly down to the VI's to live aboard our P39 cat. Given my temporary (hopefully) unemployment I'll only be able to afford the BEST magazine in the islands. The Caribbean Compass is a free monthly paper that is stacked with info about what's going on in the islands. It's a must read. They also have a website:
