About Bertram

Premium production

American sportfishing builder in Tampa, Florida, that the yard calls one of the most iconic marine brands, with more than sixty years of boats behind it — six models today, the 28CC, 34CC and 39CC outboard centre consoles and the 35 Flybridge, 50 Sport and 61 Convertible diesel sportfishers, from 9.1 to 18.6 metres.

Bertram calls itself one of the most iconic marine brands, producing recreational boats and yachts for over sixty years. Its boats are built in Tampa, Florida, and sold through a worldwide dealer network, and the company says it is rapidly expanding its production to meet demand for new products. All of the work on a new Bertram starts in-house: the product development and engineering team designs and engineers the boats, builds the tooling and the prototypes, and keeps refining the models already in production, while the Tampa plant's laminators, finishers, assemblers and marine electricians build them.
