I'll have to look into MTOA, it sounds like it might be right down my alley if they have no shill articles and no advertising. Reading almost every other boating magazine one finds article after article shilling for whoever sent the editor a free something for his boat. (growl)
I find that the GB site is extremely helpful. As I might have stated previously I was set to buy a GB but didn't for a variety of reasons. However, in the several years I was doing research on trawler style boats it was far and above the most informative.
I even tried to join the local GB club (PSGBOA) to gain more information, but was rebuffed by their website which required a hull number to join. When I complained to the webmistress about their exclusivity she denied that a hull number was required. I sent her the screen shot of the page and mysteriously it disappeared a week later with no further contact from her. That soured me from ever wanting to join that group. Yes, contact with one person tainted the entire group. Many people who belong to that group are friendly aquaintances, but those are individual contacts.
I had a similar experience with RBAW, the WA state recreational boaters association. My yacht club belongs as a group member. One year, after their marketing campaign I joined also as an individual member. I think it was $90 to join. They had a symposium on some issue that I thought was interesting and I made plans to attend. I sent in to reserve a place and was told that only recognized groups were invited to attend meetings and provide input. If I had something to say, I should send it thru a group representative and they would bring it up "if it was appropriate". Needless to say, they never received another dollar.
So, with groups like this and others, it is how well the group receives new members and how they respond to them that makes the difference. In my opinion, Boatdiesel does not serve the Lehman 120 owners. While many espouse how wonderful it is, it does not provide information to the section of the boating community I belong. They are not responsive to requests to include that information. So, for a Lehman owner it is a waste of money, IMHO.
