I am thinking of buying a 1978 O'Day 23 and would appreciate any thoughts about how capable, dry, tender etc. the boat is in up to 25 knots and 2-3 foot seas. I have heard that it is quite tender and I don't want to frighten my wife! Also about the encapsulated keel: does that mean it is encased by the fiberglass hull? I am also looking at a Tanzer 22 and would appreciate a comparison if anyone can make one. Thanks for any help!
