    According to the owner, the boat is in good running condition. The vessel is started and ran every two weeks, and the bottom is cleaned every month.

    The boat is a project, needs TLC. The engines are beautiful and still shine. There is some recent decay in the rear transom interior panel, likely not structural, see last photo.

    This Bertram was a custom boat, and manuals and actual specs are no longer available due to her vintage age.

    Buyers should use the due diligence period to verify features and specs provided by the owner.
