Sig, there are a variety of sizes of water craft in VOL Navy.. regardless of size, you'd fit in!!!
Our friends in Farragut have an almost 60' beauty.. there was a show on about Tennessee tradition and there was their yacht... have never been on board but our invite is always open...
No doubt I second this; you can tie up with me anytime but in a boat that size you have so many more options than me lol. I used to go in my 18' runabout then my 28' Glastron Cruiser and now my 34' Sea Ray.
I have seen everything from canoes to 100+ footers down there and everyone has a great time. It's a "You gotta do it at least once" kind of thing for sure!
