Broker Remarks

Powered by twin Detroit Diesel engines, Big Bertha has been the summer home of her Swiss owners for many years. She is not quite a ship; however, her internal volume is exceptional. Built by the American luxury motor yacht builder Bertram Yachts Florida in 1978. The yacht needs at the moment cosmetic maintenances this is the reason why the owner is open to any offers and flexible on the price. 

Although from our video and photos you will get some idea of her size, it's not until you step aboard that one feels the benefit of the minimalist design that fits perfectly with the current yacht design. Indeed, the Beltram 58 is a very comfortable offshore cruiser and has a fantastic liveaboard space.

We strongly recommend viewing it. She is available for viewing by appointment through Network Yacht Brokers, please contact us for more information. Photos and videos are from 2019 and 2021. 


The interior teak has been renewed in 2000. The saloon is 2,05 meters high and is composed by a table, a settee, two chairs and a separate dining area. The six berths are very well proportioned. A kingsize bed in the aft suite sets the room off perfectly along with full side to side closet. You would be forgiven if one thought it to be the master bedroom of a large apartment.
