I personally have never heard of them, at one time there were 53 companies making pontoons and those were just the larger ones, probably many more regional companies.
Just for historical information as I am sure everyone who has posted is long gone so this is for the googlers.. National become forester then they became premier pontoons. They are still building pontoons in Wyoming Minnesota.
Ha ha....Premiere is one of the best on the business. BUT, don;t try to get parts for them either, as they building which housed parts and templates burnt down a few years ago I believe.
