The marina had a wedding reception for a local waterman. That means a lot of deadrises tied up to C dock. Plus a tent. Plus a DJ. Plus some music.

There were perhaps five visiting deadrises.
It is the official Viginia state boat.
The good news is that they weren't (generally) all running their over-sized engines at once.

They generally have large engines that produce high torque at low RPM's with small water-lift mufflers (if they have a muffler at all.) They can be loud. Plus, because of the way the muffler works they have a crazy irregular beat to the engine noise. A kind of characteristic deadrise throb that carries over the water for miles.
The helm position is almost always ¾ of the way aft and on the starboard side. In a proper old-school boat, the steering is a stick with a wire loop to pull the rudder: forward for port, aft for starboard. A nicer boat will have a wheel and a Teleflex-style push-pull cable, but the wheel will be transverse mounted (i.e., sideways.)
