Ran across the Zinio page today… haven’t heard of them before (should have). They have lots of magazines, books, etc. available for online reading. Its a pay site that you can subscribe to, but you can also examine single issues (for a fee or sometimes free) of their magazines at least will allow you to see how you like it.
Nice way to check out some magazines that you may wonder about, but don’t want to subscribe to without seeing "in person".
Or, if you are living aboard or otherwise are short on space, receiving and viewing magazines electronically could be a good deal, and I’m sure has to be better for the environment.
This link is to their boating and aviation selection, which looked pretty good. Might be worth checking out.
