I completely agree with your statement if you are looking at the convenience factor. And I definitely consider myself lucky to have a place right on the water -- it pays to marry into the right family!!

But if the main issue is the blistering then it would make absolutely no difference whether the wet-slip was at a marina or at a residence.

And I also agree with your "decide for yourself" comment...........this is getting close to the religious or political question in which the only real opinion that matters is yours and no one else's opinion makes any difference in the least.
