Very nice! (Is that what they call a yawl rig? - forgive me, I live a LONG way inland.) My parents live on the GA coast, but they're up in the marsh channels and anything with ocean draft would spend most of its time on the sand bars (they have pretty substantial tides and the water runs in and out of there like a millrace.) They have a 17' Whaler and that's all they really need.
You can take your boat on our river if you like, but you won't get far. For one thing, there's not a drawbridge to be seen - the kayaks can get under but I'm pretty sure you can't.
Have you seen these yet? towboat
The captions aren't exactly correct - the true story was eventually pieced together and the guy with the pix has posted it on the website.
