Different boats have different stability patterns on a plane. The best I ever experienced was a J 105, which actually seemed more stable up on a plane. Worst was an Express 37, which would overpower its own rudder
and tended to want to broach capriciously. Most fun was an Olson 30, which on a good day could plane on just about every wave, provided you kept the crew weight aft and pumped the main at just the right moment.
boat won't even think about planing in anything less than 15' seas, and that's just fine with me. The few times we've seen her take off down a wave, we've had to laugh at how pretentious she is.
On the other hand, all she needs to hit ten knots in flat seas on a beam reach is a clean bottom. Some days I don't even need the gennaker
to hit double digits.
