Sailboats rafting up?

I’m new to the Vol Navy and I’m wanting to raft up for some games.  I have a big problem though.  I have a sailboat with a 50′ mast that wont fit under the railroad bridge.  I could heel the boat to one side and reduce the height of my mast enough to get under the bridge but that’s a bit tricky and dangerous.  Have other sailboats rafted up with the Vol Navy in the past?  Are there other places to raft up or anchor?  Maybe there is place down river from the railroad bridge but still close to the stadium.  My boat is a 30′ Catalina with a draft of 5’5″ and a beam of 11′.  Any thoughts.
