The Cheoy Lee Offshore 47 is a bluewater cruising ketch designed by Alfred E. Luders and built by Cheoy Lee Shipyard in Hong Kong starting in 1973. Part of Cheoy Lee''s highly regarded Offshore series, the 47 features a fin keel with skeg-hung rudder, lead ballast, and a masthead ketch rig carrying nearly 1,000 square feet of sail area. At 26,500 pounds displacement with a comfort ratio approaching 40, she delivers the seakindly motion and offshore capability the Luders-designed Offshore series became famous for. The 47 was offered in sloop and yawl configurations as well, though the ketch was most common. Construction is solid fiberglass throughout with interior fit-out to Cheoy Lee''s high standard, and many examples have completed multiple ocean passages.
