[1][2][3] The design was built by Seidelmann Yachts in Berlin, New Jersey in the United States between 1981 and 1984, but it is now out of production.
[1][3][4] The Seidelmann 245 is a recreational keelboat, built predominantly of fiberglass, with wood trim and aluminum spars.
It has a 7/8 fractional sloop rig, a raked stem, a vertical transom, a transom-hung rudder controlled by a tiller and a fixed stub keel with a centerboard.
The fresh water tank has a capacity of 10 U.S. gallons (38 L; 8.3 imp gal) and is filled from a deck filler.
The galley is split, with the single-burner stove to starboard and the sink on the port side.
