Re: Bertram 25 ???? do you recognize it? help please
I'm sure there are lots of factual reasons the Bertrams are sought after, hull design, strength, etc... but I'm no expert and couldn't tell you the exacts. The truth is any of the older, and possibly even newer Silvertons are considered to be a mid tier boat, while an old Bertram is considered an upper tier. With that said, this is not my opinion, as my next boat will most likely be an older model Silverton.
The Bertram name has been associated with the beginings of modern powerboating, as well as fiberglass. They were considered the high end "battlewagons" of their time. Some people will go to great lengths to get and restore them. Silvertons don't have the same type of following, from what I have seen.
Hopefully none of this takes away your desire to possibly puchase the boat pictured. If theres potential there, and she suits you well, don't let the name stear you away.
Good luck.
