EQUINOX II is a classic Bertram 31 FB cruiser. She was refit in 2011 by her former owner on the West coast, and major improvements included new 2011 Peninsular 400T Diesel engines (only 305 hrs on engines), new GPS plotters, additional electronics & Flybridge and cockpit seating canvas covers.

In staying with tradition her current owners also made improvements since their purchase in 2022. Her topsides were awl-gripped dark green with a single white boot top and she has always been well maintained by a reputable Maine Boatyard and stored inside a building during the off season. Lightly used for short day trips and with low hour newer diesel engines, EQUINOX is a great vessel for those looking for all the benefits the BERTAM name has offered her owners for generations.

DESIGN COMMENTS & INTERIOR & EXTERIOR

Today the Bertram 31 continues to be a very popular family cruiser.  Her Hunt design is extremely well respected in the marine industry and is often the "yard stick' other designers use to measure features that make for a vessel's safe and comfortable offshore ride.  Her deep-V hull, long strakes, and bow flare are perfect for choppy seas, offshore passages or just carving through calm waters on a summer morning.

INTERIOR:

EQUINOX II has a simple and practical interior with single V-berth forward, dining area (that converts to berth) to port with the head just to starboard.  The lower fully-equipped helm station with repeat GPS Plotter and VHF is forward of the head.  Convenient pocket-style doors enclose the companionway and head area.

EXTERIOR:

The Bertram 31 has always been known for her palatial sized cockpit.  Great for entertaining with multiple folding chairs or space for a fighting chair for the avid fisherman.  Forward facing aft cockpit seating has new blue Sunbrella canvas weather cover to match the flybridge awning and weather covers too.  A sturdy stainless steel ladder allows easy access to the fully equipped flybridge including plotter, engine instruments, helm and more.  A custom highly polished radar arch was added to the boat during her 2011 refit to mount the Furuno radar and more.  Great engine access through the removable cockpit engine box covers.  EQUINOX II is a true classic cruiser, respected by the saltiest of mariners and she is ready for a new owner to enjoy immediately.

ADDITIONAL INFORMATION
