Whitby Brewer Sailboat Association
This is the main site for Whitby / Brewer owners and hopefully potential owners. The new structure is excellent but content appears slow in coming.

Doug Stephenson's Whitby Brokerage
Doug Stephenson Brokerage Website (Doug is a broker and recognized expert on Whitby/Brewer vessels). If you are serious about a Whitby you should contact Doug.
Bernard C. Boykin edited approx 20 newsletters starting in 1991 (I believe). These are an outstanding resource and contain a wealth of information and if you are investigation a Whitby 42 you should try and locate them. Most original owners should have copies. I have scanned copies of these in PDF format, for my own use, but cannot post them here for fear of offending (once again) the Owners Association.
If you are in the market for a Whitby 42 or any used sailboat pick up a copy of John Kretschmer's "Used Boat Notebook" which has a review of 40 used sailboats including the Whitby 42. (Get the 2002 edition which has the Whitby not the 2007 edition, or get both.) I like John's reviews as he has vast sailing experience and know's what he is talking about.
Any google search will throw up Jack Hornor's review on the Whitby 42. His main criticism of the Whitby 42 was
"that the deck-to-hull joint of most Whitby 42s is fastened with pop-rivets, fiberglass and resin. Some 42s were built with the deck-to-hull joint completely through bolted--my preferred method. Whitby offered this as an option at an extra cost. I will admit many Whitby 42s have made significant offshore passages, and I am not aware of any catastrophic structural failures. "
This is one item that needs urgent clarification from the Owners Association. It would be realitvely easy to try and ascertain how many Whitbys' actually had bolted tru hull-to-deck joints. I know mine certainly were.
In any event if would just take a 5 min. inspection to check if the hull-to-deck joint was bolted or not. I would be slow to buy a Whitby that was not bolted.
Cruising World - Classic Plastic - May 1998.
