The 2001 Eastern 31 (often called the Eastern 31 Casco Bay) is a Downeast-style fiberglass powerboat built by Eastern Boats in Milton, New Hampshire. It is a recreational/cruising version of a proven semi-displacement hull design descended from the earlier JC 31 workboat, which was popular for commercial use along the New England coast. 

Design and Hull

Naval architect Royal Lowell designed the hull, featuring a graceful sheer, hard chines, and a long prop-protecting keelfor good tracking and protection in shallow or rocky waters. It is a semi-displacement hull that balances efficiency, load-carrying ability, and seakeeping. These boats have a strong reputation for handling rough conditions (such as chop and bigger seas) well for their size, making them popular for coastal cruising, fishing, and day trips in areas like Casco Bay, Maine. 

Key dimensions (approximate, can vary slightly with options/configurations):

• LOA: ~31'–31'4"
• Beam: ~11'–11'3" (around 11.17 ft in some listings)
• Draft: ~3'6"
• Displacement: ~12,000 lbs (dry weight)
• Headroom: ~6'4" in the cabin

We've owned Sapphire for five years and are only her second owners. We named her Sapphire after a favorite ski run at Okemo Mountain, fittingly, the last trail we ever skied there together as a family. She has been well loved and meticulously maintained throughout our ownership. Some of our favorite memories were made exploring the Boston Harbor Islands where we'd spend long, easy days on the water with family and friends aboard. We took a memorable trip to the Cape Cod Canal to see our daughter off as she departed on the URI RV Endeavor  for a research expedition, a day we'll never forget. We've watched planes glide in for landing at Logan from out on the water, spotted a whale out past Graves Light, and docked for dinner nights in Hull. Anchoring off Gallups Island for a full day of sun and swimming is always a favorite. Sapphire has given us countless fabulous days on the water!

We have decided to sell Sapphire to move into a trailerable boat that we can use closer to home.
