The Swan 46 Mk I, also just called the Swan 46, is a Finnish sailboat that was designed by Germán Frers as a cruiser-racer and first built in 1983.

 

The design was originally marketed by the manufacturer as the Swan 46, but is now sometimes referred to as the Swan 46 Mk I to differentiate it from the improved 1989 Swan 46 Mk II and the unrelated 2004 Swan 46 Mk III design.

 

The design was built by Oy Nautor AB in Finland, from 1983 until 1997, with 109 boats completed, and average of 7.2 boats per year.

 

The Swan 46 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a wheel and a fixed fin keel. It displaces 31,300 lb (14,197 kg) and carries 11,400 lb (5,171 kg) of lead ballast.

 

Easy Day has a draft of 8.20 ft (2.50 m) with the standard fin keel

 

The boat is fitted with a British Perkins Engines diesel engine of 65 hp for docking and maneuvering. The fuel tank holds 99 U.S. gallons (370 L; 82 imp gal) and the fresh water tanks has a capacity of 127 U.S. gallons (480 L; 106 imp gal).

 

The design has sleeping accommodation for seven people, with a double "V"-berth in the bow cabin, a "U"-shaped settee and a straight settee in the main cabin along with one upper pilot berths and an aft cabin with a starboard double and port single berth. The galley is located on the port side just aft of the companionway ladder. The galley is of straight configuration and is equipped with a three-burner stove, an ice box and a double sink. A navigation station is opposite the galley, on the starboard side. There are two heads, one in the bow cabin on the port side and one on the starboard side in the aft cabin.

 

The design has a hull speed of 8.24 kn (15.26 km/h). The PHRF handicap for the standard mast is 63 to 72 for the fin keel model.

 

In a 2014 review in Sailing Magazine, Bob Pingel noted, "Frers loved the Swan 46 Mk I, saying the boat is 'beautifully responsive to sail, small enough for two or three competent crew to handle, yet big enough to accommodate a family of six in complete comfort.'"

 

In 2008, Easy Day went through an extensive refit to add a carbon fiber pilot house over the companionway to keep the crew out of the elements on long passages.  From this shelter,  all instruments, radar, VHF, AIS and autopilot can be accessed.
