The Cape Dory, while a nice boat has a somewhat dated design and certainly does not have a modern underbody. This will not be a fast boat. By Brother-in-law has had two (Typhoon & CD25D) and they begin to have some issues with crazing of the gelcoat and cockpit delamination after so many years.
Hunters from the 80's are pretty good boats; a friend and his wife cruised 2 years on a 37.
The Sabre 30 is a very nice boat; I've had 2 Sabres (28 & 38) and can write volumes on construction, etc. While it has a more modern underbody than a Cape Dory, it's not what I would call "2000's modern". This boat does not have a protected rudder but to be honest, I'm not sure that you need it given your requirements. On this boat, the keel is deeper than the rudder so your keel will impact anything before the rudder. Sabre's quality is excellent and you can't go wrong with one. It's good in light air and very sea-kindly. PM me if you'd like more details.
