Some suggestions:
IF that's you boat in your avi, bring enough fenders for both sides n plenty of them. There will likely be some BIG boats tied up next to you.
The boats all tie up to each other and stack up sorta like dominos. You'll want to position yourself so people can walk across the back of you boat or swim platform. Trying to make "overserved" Vol fans walk across your platform is risky. You may b helping fish them out of the water
I've seen it happen more than once.
Bring a rug or heavy duty towels to cover your floor n seats as people cross going to other boats. Fans don't always wear "boat shoes". And, yes the will walk on your seats.
Don't be in a hurry to leave. If there are 10 boats tied out beyond you they aren't going to be eager to accommodate you by re-arranging and re-tying up. It can be a cluster F*** when boats start leaving.
Bring a hand held spotlight to help navigate in case you leave after dark.
A DD is a good idea. The rabbit sheriff is out there and U will get a BUI which is just like a DUI. $$$ and loss of TN drivers license for a year.
Most of ALL - Have Funn. Being part of the Vol Navy is some of the most fun I've ever had - with my clothes on
Also drown any Gators you may encounter on the TN River.
