The Power Boat Guide had this to say;
The Sea Ray 390 Sedan is basically a stretched version of the earlier 360 Sedan built in 1980–82. The extra length went into the cockpit that, with over 100 square feet of space, is one of the boat’s most impressive features. She rides on a solid fiberglass hull with a relatively wide 13-foot, 11-inch beam and propeller pockets to reduce shaft angles. The two-stateroom, mid-galley floorplan of the 390 remained essentially unchanged during her production run, although in 1985 a walkaround bed replaced the original angled double-berth in the forward stateroom. Single berths are located in the guest cabin, and a serving counter separates the galley from the salon. The comfortable cabin accommodations make the 390 an excellent all-purpose family cruiser, and with plenty of fuel and a big cockpit, she’s capable of some serious fishing activities. Additional features include a transom door, swim platform, and bow pulpit.
