Boston Whaler's flagship dayboat well-maintained, and finished in a Sand Metallic hull you will not find many on the water.

The 380 Realm is the boat that redefined what a dayboat could be open-bow social space, a fully enclosed cabin and head for weekending, and the offshore backbone of a true Whaler. This particular hull pairs that pedigree with an owner who maintained it to captain standards. A hull paint in Sand Metallic paint sets this Realm apart from every white-hull example on the market understated in the slip, unmistakable underway. Quad Mercury V8 300-HP FourStrokes with just 500 hours, joystick docking with Skyhook station-keeping, and cruise ready from the first turn of the key.

Comfort that holds station. A Seakeeper gyro keeps the deck flat at rest, the diesel-generator 12kW upgrade and reverse-cycle A/C run the cabin and cockpit all day, and a refrigerated leaning post plus freezer plates keep provisions cold to the horizon and back. Unsinkable by design. Like every Boston Whaler, the foam-filled hull is engineered to stay afloat the rare luxury cruiser that doubles as peace of mind.

A fully optioned example showcases the upgrades buyers often consider, already installed on the boat.
