I subscribed to Messing About In Boats magazine when I was in high school, which was… a while ago. It is published not far from where I grew up outside of Boston. It certainly isn’t polished – they still seem to be in black and white – but it is well done and has good small boat content of all kinds. I recommend it and am sorry I can’t get through the reading material I do get, because it would be a nice add. Pleasantly surprising is that there are online archives with some useful looking short articles.
