I consider myself extremely lucky to have found an open-back 2520 that I bought from the original owner.
I cannot imagine having to go back to being isolated in the cabin while everyone is enjoying the dance floor that is the cockpit in this boat.
Because I'm not isolated, and because the cabin essentially becomes an extension of the cockpit area, the boat just feels larger and more open.
The open-back is a no cost option that frankly, more dealers should consider when marketing these sport cabin boats.
When I replaced my drop curtains, I had the canvas guy eliminate the windows for a couple of reasons:
1.) I never run with the curtains down, even in cooler weather.
2.) The drop curtains roll tighter without the windows in place.
3.) Eliminating the windows keeps prying eyes at bay.
4.) and finally, eliminating the windows made the job less expensive.
Prior to having this set made, my canvas guy noticed that I was using clothespins to keep the center section open about 12" to allow for ventilation.
What he did for me was to add 3 additional snaps in that panel so I could eliminate the use of the clothespins.
Finally, I had a matching rear station cover fabricated. The whole job was done in Sunbrella, and it has held up very well.
Attached are some photos showing the various methods I use when running, at the dock, or entertaining.
