Design
The Swan 47-2 is a racing keelboat, built predominantly of polyester glassfibre, with wood trim. The hull is solid fibreglass, while the deck is of fibreglass sandwich construction. It has a masthead sloop rig, with a keel-stepped mast, two sets of unswept spreaders and aluminum spars with discontinuous stainless steel rod rigging. The hull has a raked stem; a raised counter reverse transom; a skeg-mounted rudder controlled by a wheel and a stub keel with a retractable centreboard. It displaces {{convert|34400|lb|kg|0|abbr=on}} and carries {{convert|17500|lb|kg|0|abbr=on}} of lead ballast.
The boat has a draft of {{convert|8.00|ft|m|abbr=on}} with the standard keel.
The boat is fitted with a Swedish Volvo Penta MD21A diesel engine of {{convert|61|hp|kW|0|abbr=on}} for docking and manoeuvring. The fuel tank holds {{convert|96|u.s.gal}} and the fresh water tank has a capacity of {{convert|130|u.s.gal}}.
The design has sleeping accommodation for five people, with a double "V"-berth in the bow cabin, an L-shaped settee and a straight settee in the main cabin and twp aft cabins, one with a double berth on the starboard side and a single berth cabin to port. The galley is located on the port side just abaft of the companionway ladder. The galley is a split design 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 just aft of the bow cabin on the port side and one on the starboard side, aft.
For sailing downwind the design may be equipped with a symmetrical spinnaker of {{convert|2207|sqft|m2|abbr=on}}.
The design has a hull speed of {{convert|8.07|kn|km/h|abbr=on}} and a PHRF handicap of 69 to 84.{{cite web|url= https://www.ussailing.org/competition/offshore/phrf/phrf-handicaps/|title= PHRF Handicaps|access-date= 14 April 2023|author= US Sailing|author-link= US Sailing|work= ussailing.org|year= 2023}}
