Incredible opportunity to own a fantastic one-of-a-kind yacht at a rock-bottom priceSea Eagle III is on the market again, and is currently undergoing a refit by her current owners. More photos & videos coming soon, as her refit continues! Owner financing available with 50% down.

Sea Eagle III began her life as a 58' Bertram, built in 1977. Then, in 1989, Derecktor Shipyard in Dania, Florida, added a 13' $500,000 extension that added two en-suite staterooms aft, a larger salon and a larger flybridge. She now offers five staterooms plus room for crew, a separate dining salon and a full lower control station. She has undergone continual upgrades from her different owners, including rebuilt 12V71TI's, a total repaint, professional interior design work, and much more! She's part of a film project that is currently in production, where the owners are chronicling her refit and have added countless extras since they purchased her.

The price is negotiable depending on the current stage of the refit process. You could choose to buy her as-is for the price listed, or wait for the refit to be complete. Owner estimates that the refit is 80% complete, and once she is refitted her value will skyrocket. She can be custom finished for another $200,000, and will be perfect in every way. She could easily be chartered for $15,000 a week, or serve as someone's private luxury vessel. Either way, come see this special vessel!

History & Broker's Comments

In 1989, Sea Eagle's owner commissioned Dave Napier, the original designer of the Bertram 58, to design an extension for his 58' Bertram that would include two additional staterooms and an enlarged salon and deck above. Derecktor in Dania, Florida completed the refit at a cost of well over $500,000. Dee Robinson then designed a beautiful interior.

In 1993 she was purchased by a new owner. Continual upgrades by a conscientious owner included a $70,000 rebuild of the main engines in Fall '99, repaint of the topsides in the Fall of 2000, etc. 

She has been used for both personal cruising and charter operations from Nantucket to Granada. She offers unparalelled facilities, including four double staterooms plus crew, large upper Salon with Dining Salon below, enormous Flybridge with dining area, etc.

Her current owners are in the process of yet another refit, making this one of the most well-preserved and well-taken-care-of motor yachts on the market. She is a special boat!
