Description

Wow is one word that describes the last of the great Bertram MY shes a 100% fresh water boat. We are proud to be offering Tenacity she's the last year Bertram built their 58 Motor Yacht in that Era. She was ordered new by a West Michigan man who had his great friend fly monthly to the factory to oversee the build with all the custom upgrades that the owner has ordered. The list of custom factory options are extensive. Just to name a few were hydraulic bow thruster and also a crash pump system with an emergency valve if you had a hull breach she would be able to be saved like no other vessel back then. She has been serviced and well cared for by all owners and has always been in heated storage. The hull sides shine like the day that she left the factory and her chrome and stainless shows as new as well. I could go on and on but you will have to see her for your self. Call today to step aboard this incredible Yacht.

Full Details

Overview

Manufacturer

The Bertram 58 Motor Yacht is over 43 tons of sheer grace and pure power. Imagine a vessel so spacious that ten people can embark on an extended voyage without feeling crowded or confined. Even the flybridge can accommodate eight comfortably, as the soft ride of the Bertram deep-V hull glides over jagged waters at 26 miles an hour in conditions that other yachts would find a hardship. And yet, for all her grandeur, this 58-foot masterpiece performs with amazing economy. A foredeck with a built-in lounge is large enough to serve as a private terrace, while the cabintop can serve as the perfect sundeck. The aft deck is a patio for cocktail parties, champagne breakfasts, or just plain lounging and relaxing. The stereo systems, air conditioning, wetbars, ice makers and remote-control televisions are all standard equipment. The salon is an arena of luxury, equipped as it is with an electronic entertainment center, a dining table and a unique salon - galley divider. The galley is elegant and complete. The forward stateroom features upper and lower berths with ample closet and drawer space. Also included is a built-in ladder and shelf for quiet, unnoticed arrival and departure. The amidships guest stateroom is equally as private. This room adjoins a full-size head with a shower and comprises twin beds with plenty of locker and drawer storage. The master stateroom has a full side-to-side closet, hideaway vanity, remote-control TV, desk, and a king-size bed with bilge alarms and light controls conveniently built into the headboard. A shower and bathtub round out a full-size head adjoining this stateroom.
