im MartinB

So I am just one boat ride in on a new to me catamaran. I've been up to 70 mph so far and I'm not sure if it really feels much different than a V bottom up to this point? Okay turning feels a lot different, but running straight maybe smoother but that's about it. My question is there an obvious point when you start to pack air or is it just a the faster you go the more lift ie gradual and hard to notice. I notice also that unlike my V bottom, which takes more and more TRIM the faster I am going, this catamaran seems to plane out about 40mph and take a couple nice bumps of trim and then even if I add 30 MPH it doesn't seem to want or need any additional trim at all...
