The mess on the back looks like the optional swim platform. If you remove the optional stuff on the boat it looks like the old 21se with a liner and optional bow V seating in place of the casting platform. Tri State Marine stilll has the 2022 21se for sale that we all know and love....The features list has a 4K add for an aft/swim platform! What is that mess hanging off the back? I love the rub rail that does nothing back there.
