Bayliner had some of the best layouts and this one doesn't disappoint! Lots of room and natural light surrounding the salon and galley areas. Such a great value for a cruiser with diesel power and low hours!

Not only does she have low hours but the interior has teak treatments in stellar condition. Showing little wear for her age!

With the extra stateroom and head bring along company. Engine room is easily accessed from the cockpit with a separate entry door.

Sleeps a total of 6 persons, 2 on folding salon settee, 2 on master centerline double and 2 on VIP king amidships.
