First, what are your anticipated pontoon boat uses? Age and personality of family and guests that will typically ride on it? I would argue this really can make a HUGE difference in which layouts lend themselves best as there are many FANTASTIC layouts.
We got a Swingback in 2017. It suits us perfectly! My wife and I like being able to lay out there together so we liked that better than the CW…although we really like that layout too.
Our swingback area is a huge hit with our kids (ages 17-27 for reference), their friends, and our nieces & nephews (all older teens to adults too). It’s also an amazing spot for spotting during water sports, and the spotter can easily have 1-2 others laying back there with them for company. And don’t even get me started on the storage space under that lounger. Love it! So for us, the swing-back is a home run.
Now if we had preferred our own individual seating spot for lounging around, the CW would have been next up on our list. And if we had younger kids to keep more corralled for safety, we’d have leaned towards the quad bench layout. We’ll never cook on the boat, so any dinnette options we unnecessary, but look oh so nice!
My point is there are so many customized layouts and floor plans to fit MANY different uses. Thus, take many of our ideas (mine included) with a pinch of salt. Our uses and passengers may not match yours well.
Think about what you will be doing with your boat. Who will be on it? What activities will you enjoy while on the water? What safety, activity, lifestyle, aesthetic, etc… visions/needs do you have? Then pair that up as best you can with one of the layout options.
