The Delta 31, also called the Albin Delta, is a Swedish sailboat that was designed by Peter Norlin as a cruiser-racer and first built in 1983.[1] [2] [3]
The Delta 31 was designed as a replacement for the Ballad 30 in the company's product line.[3]
The design was built by Albin Marine in Sweden from 1983 to 1986, with 300 boats completed, but it is now out of production.[1] [4]
The Delta 31 is a recreational keelboat, built predominantly of fibreglass, with wood trim. It has a fractional sloop rig, a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel. It displaces 85980NaN0 and carries 35050NaN0 of ballast.[1]
The boat has a draft of 5.9feet with the standard keel and is fitted with a Japanese Yanmar 1GM diesel engine of 80NaN0 for docking and manoeuvring.[1]
The design has sleeping accommodation for six people, with a double "V"-berth in the bow cabin, an U-shaped settee and a quarter berth in the main cabin and an aft cabin with a double berth on the starboard side. The galley is located on the port side just forward of the companionway ladder. The galley is equipped with a two-burner stove and a round sink. A navigation station is aft of the galley, on the port side. The head is located just aft of the bow cabin on the starboard side.[5]
In a 2009 review Yachting Monthly described the design as, "a sleek, powerful, fractionally rigged cruiser-racer".[3]
