Unique Opportunity for Affordable Waterfront Living
Have you dreamed of living on the water but assumed it was out of reach? Looking for a unique waterfront retreat, floating Airbnb, dockominium, or year-round liveaboard without the price tag of waterfront real estate? WYNWARD offers an exceptional opportunity for the right buyer.
Offered at an exceptional value, this 1976 Marine Management 48 is mechanically sound with extensive investments in her systems and infrastructure. While cosmetic work (including carpentry, paint, and fiberglass) remains, the costly mechanical, electrical, and infrastructure upgrades have already been completed, making her an ideal opportunity for someone who's handy and ready to create something truly their own.
Powered by twin 325 hp GM 8V-71N Detroit Diesels (overhauled in 2005), WYNWARD cruises economically at 8 kts burning 8 gal/hour and can cruise up to 17 kts when you need some speed. She features two staterooms, two heads with separate showers, a full Galley with like-new appliances (including a washer/dryer), generous storage, and an expansive full-beam salon ready for your vision.
Offered as-is, WYNWARD is an affordable alternative to waterfront real estate and a rare chance to create a one-of-a-kind floating home, weekend retreat, income-producing rental, or liveaboard cruiser. Her fascinating history, including years as legendary designer Jim Wynne's personal yacht, is an added bonus.
Currently on the hard in Newburyport, MA, she is ready for her next owner to complete the transformation. The seller is highly motivated and has recently reduced the price for a quick sale.
