I have some personal and 3rd party information about the Ray Richard's designed Cheoy Lee Offshore 41.
First, I own a 42-foot Cheoy Lee sloop...for the past 20 years. Second, I chartered an Offshore 41 in Tortola many years ago and sailed her throughout the U.S. and British Virgin Islands with my family for about a month. Enough to get a real feel for her. I also have some friends who several years ago bought one in Tortola, proceeded to do major structural improvements (like strengthening bulkheads), and sailed her to the South Pacific and back to Alaska and California. Finally, I have visited Cheoy Lee's yard several times and have seen these boats building.
The Offshore 41 is an interesting design. It sails very well. It's about as fast as a Valiant 40 (I once raced a Valiant 5 miles in breezy conditions from Foxy's on Jost Van Dyke to Sopers Hole on Tortola....a draw).
The hull is very well built, like most Cheoy Lee's. Very strong. The exterior teak and spruce mast, if fitted, can be a bear to keep up. Interior joinerwork is typical of Cheoy Lee: beautiful on the surface, and functional. My kids particularly liked the round "playpen" at the forward end of the main cabin.
Like many Cheoy Lee's, though, she will have some substandard metal you'll want to get rid of over time, if previous owners haven't already done so, and some leaks. "Cheoy Leaky", and all that.
That she's an older vessel may not be a show stopper, depending on how she's been cared for over the years, and depending on your skills and pocketbook to keep her spiffy. Liveaboards and "round the buoys" sailing in the Bay can get away with letting some things go awhile. But, before you take her offshore, you'd want to be certain her standing rigging, including chainplates, have been inspected and passed by a competent rigger, and that her other mechanical and electrical systems are in good repair.
You might check out the Cheoy Lee Owners Association for some contacts and more info.
Hope this helps a bit.
