It's not an essential piece of gear for sailing the Chesapeake, but it wouldn't hurt. If you had one, I'd keep it. If you don't have one, I wouldn't rush out and buy it.
I have personally laid eyeballs on your boat, as I was visiting a friend's boat. Very nice ride.
The West River has a "float free channel" that leads out to the Bay. Although the crabbers frequently encroach on the float free zone, it's better than driving through the main body of traps, so I advise you to get familiar with the locations of the white/orange informational bouys that mark the channel, and plug them into your GPS.
Also, be advised that the West River and Pirate's Cove Sailing Clubs put race marks out in the water that resemble the float-free info bouys, so be careful.
The race marks are usually light gray, and most (but not all) of them have a pointy cone on top.
Hope that helps, and hope to see you out there.
