I never argue with you Ronnie, as your advice is golden around here. But it just so happens I took a large (to me) group out on Saturday and I had to take a look at my placard (behind the throttles on our 2011 242ls) Coast Guard says 11 on that model year, and as you stated, 2010 to 2014 240/242 should be the same. (someone told me they upped it from 10 to 11 in 2011 for some reason, but the boat didn't change) I had to count my life jackets twice as well. Holiday weekends bring all the "bush pigs" out and I wanted to be legal with a full boat.
We ended up with 9 adults (some 20 year olds) and boat handled well. The biggest thing as a captain as Ronnie mentioned, was space management. Ask everyone to put bags, towels, shoes clothes away when possible. As the floor had two large RTIC coolers.
Weight distribution was not as much of a problem as expected. Other than I asked my wife to keep folks sitting once we balanced the boat for putting it on the trailer. 99% of the time, the boat goes through the guide posts and half the troop stands up to grab their crap and the boat loads uneven.
While under way, that 24' hull rides smooth going out, but we came back in bigger waves due to weather, but still handled well. Honestly, I think the load made it better. Power wise, it's a non issue. It gets up on plane easily. A big of porpoising, but that was managed with throttle.
Best of luck to the OP, I think you will be just fine.
