“Dolphin” is a Classic Bertram Flybridge that has been well cared for and has received extensive upgrades from its current owner.

Repowered in 2006 with twin 330hp Crusaders – approximately 500 hours.  During the repower, new transmissions were installed as well as new 3-Blade props, new shafts, oversized rudders and new engine wiring and gauges.  A 168 gallon ethanol proof fiberglass fuel tank replaced the original tank.

2018 – New Garmin XSV GPSmap with Radar.

Recent batteries with ProMariner ProSport20 On-Board battery charger.  

“Dolphin” is turn key and in the water ready for sea-trails. 

Manufacturers Description:

With over 2,800 built, the Bertram 28 remains the bestselling Bertram ever. Designed along the lines of the classic Bertram 31, the 28 quickly established her reputation among serious anglers as a rugged and durable offshore fisherman with comfortable cabin accommodations. She rides on a solid fiberglass deep-V hull, and the 11-foot beam is wide for a 28-footer. Below deck, the cabin layout includes berths for four with a convertible dinette, an efficient galley, stand-up head, and plenty of storage
