Greetings,
Mr. X. As mentioned, Passagemaker is about the only one I know of. Many moons ago when it was first started by Bill Pantaloons it was a good publication directed toward the "average" owner. Not terribly pretentious and full of interesting articles that I, for one, appreciated.
MY opinion only:
Since being taken over by a major publishing house, PMM has become a paid advertising platform geared toward the "rich and famous". Well, maybe not so much the famous but NOT to boaters like myself (NOT rich either).
At it's onset, there were at least one or two articles about repairs and/or modifications that could be undertaken by boaters not unlike a lot of TF members. Articles about owners and boats doing boating "stuff".
I qualify the above statements with the disclaimer that I have not opened an issue of PMM for a long time and it may have changed...
YMMV
