Builder production years: Ericson Yachts built Independence 31 from 1977 to 1981
Designer: Bruce King
Notable: various recent refits and upgrades listed above
The 1979 Ericson Independence 31 was designed by the renowned Bruce King. This cruiser-racer was built by Ericson Yachts from 1977 to 1981 and has earned a well-deserved reputation for its seaworthiness. Engineered for comfort and stability, the Independence 31 features a transom-hung rudder and a modified full keel with a cutaway forefoot. This innovative design not only enhances its tracking capabilities but also minimizes the need for constant helm adjustments, ensuring a smoother sailing experience, especially on extended passages. Sailors will appreciate how this vessel performs in various conditions, from heavy weather to light winds.
The layout is traditional, with warm teak throughout the cabin combined with bronze opening portlights and large hatches for extra ventilation. Unlike many performance-oriented vessels, the Independence 31 prioritizes storage for long-term provisioning, offering deep lockers and shelving behind the settees. The galley is to port and is equipped with a two-burner stove with oven, an Isotherm refrigerator/freezer with a new compressor and cooling plate, and all new plumbing with new foot pumps and faucets for both fresh and salt water as well as a 12V pressure pump. Located to starboard is the navigation station, meticulously organized and fully outfitted. The salon features two settees, with the starboard converting to a double berth for extra guests. Forward to starboard is the ensuite head with a rebuilt manual Baby Blake toilet, a rebuilt black water tank, and a macerator pump with spares. The plumbing and seacocks are new, and the headliner in the head was redone. A privacy door separates the forward cabin from the salon, leading to a cozy double berth with a spacious hanging locker and ample storage throughout. For enhanced energy efficiency, the interior lighting has been upgraded to LED fixtures.
Powering this vessel is a well-maintained Beta Marine 25hp diesel engine, which was replaced in 2019 and is complemented by a new 75 A/h alternator.
The current owner has produced several informative walk-through videos available on YouTube, showcasing the layout and systems onboard. The S/V Penumbra is well cared for, turnkey, and ready to go now!
