We also have to remember that like a lot of timid people, Lynn is seething with resentments that she cannot share with the people actually aggrieving her if they can potentially fight back. What has always impressed me as being her exaggerated dread of being physically mangled for expressing a contrary viewpoint means that her family always had to guess what the "OH, Nothing!!!" that was bothering her happened to be. They would have remained in ignorance were in not for the strip telling them.
What this tells me is that at some point, Lynn had decided that she had quite enough of the boating community and decided to explain to them tat they couldn't bomb along at random and make her life worse with their noise boats any longer the only way she could: by writing a comic strip arc that lumped them all together as loutish dolts in the hope that they would read it and be shamed.
