2005 37 Duffy - Classic Downeast Cruiser with Cummins Power

POTION is a beautiful example of a traditional Maine-built downeast cruiser, combining timeless lines with reliable performance and modern upgrades. Powered by a single 450 HP Cummins engine, she offers efficient and comfortable cruising at displacement and semi-displacement speeds. A Westerbeke generator ensures dependable power at anchor or underway, supporting onboard systems and amenities for extended cruising.

The spacious, well-appointed cockpit and pilothouse provide excellent visibility, ventilation, and comfort, making her ideal for weekend getaways, coastal cruising, or serious passagemaking. Updated Garmin electronics including dual 12 inch screens along with Simrad autopilot bring modern navigation to the helm, while classic Duffy craftsmanship shines through in her clean lines, solid construction, and fine joinery.

If you are looking for a proven downeast vessel with updated systems, classic appeal, and real offshore capability, this Duffy 37 deserves a close look.
