47' Alden Dolphin


"DEA" is a fine example of this traditional John Alden designed deck saloon, built in the Hodgsdon Bros yard in East Boothbay, Maine.  If you've ever wished for a deck saloon with the pedigree of an Alden now is your chance, you won't be disappointed.

Like her sisters, this vessel is traditional in every manner. Her interior boasts fine carpentry and warmth and her elegant clipper bow and wine glass transom turns heads in every harbor.

Her accommodations are roomy and sturdy and lend well to what she was built for, a comfortable bluewater cruiser. She is not lacking in storage necessary for the cruising lifestyle - her aft lazarettes take care of the deck gear and the interior has an abundance of lockers and storage areas. She has two private staterooms offering privacy to the owners and guests, bright and airy raised saloon with plenty of ventilation and great headroom throughout.
