I have used a boat for 5 years that I sit in 99% or more of the time .I find that as I age I am a bit less steady and never needed to stand up to hammer lips anyway. ease of movement front to back is nice as well and I enjoy a nice center console with high sides on the boat quite well . I mind taking a swim when I don't want to and for sure have come close a few times standing up in a boat . Especially them fancy ones with the mind of its own trolling motor thingee ....
lol ...
my buds Carolina Skiff is a pretty nice rig , and I also ride in a few other center consoles I like as well . you might want to think about a center console in my opinion ....good luck to you on your search
