We need a little more info to help you. Bigger boats cruise better, small boats doo tricks better. Doo you have 2 footitis or do you want to jump up to 23 foot? what about watersports? Will you get a tower? The speedster200 is a nice package w/ 310 HP. I love my SS Mirage and 210 HP is enough for me. When I whip past people at 50 MPH I get a huge grin.
. I am going to hold out for a 240 horse merc model because we all know the only thing better that power is more power. Does anyone have a preference or can give my a little guidance?
My 18 ft boat is comfortable or 4 adults, but close. I have carried 7 adults and teenagers, and that was crowded.
You also need to think about full windshied vs sport (pop-up) windshields. Both have their advocates.
For pure carrying capacity I would suggest an Islandia. For fun and power, I would get a 240HP Speedster. My Mirage, like a Utopia, is in the middle ground.
