Re: SWING KEELS GOOD or BAD?
IMHO fewer moving parts underwater is better; when I was looking for a Catalina 25, I didn't even look at the swing keel models.
Failure mode 1: the cable breaks while the keel is down and you are stuck in deep water.
Failure mode 2: the cable breaks while the keel is up and the keel (1900#) swings down until it hits the stop (which might not). This could let the green monster into the people tank.
Failure mode 3: The boat surfs down (or falls off) a wave and the keel retracts a bit; at the bottom of the wave, the boat stops but the keel keeps going. See #2 above.
Centerboards aren't as problematic, but I still prefer a solid keel.
