Emerald - USS Hibiscus / Frances Wright (2/4)

Shipwreck Emerald
Unique along the entire coast, the twin steam engines of the Emerald pretty much clinch the identification of the wreck.

The large box-like structure in the foreground is a condenser. Often, these old engines derived as much motive force from the vacuum draw of the condenser as from the steam pressure of the boilers. Some were even known as vacuum engines.
Shipwreck Emerald
The boilers lie in front of the condenser, and rather broken down. They are smaller than you would think - perhaps these were vacuum engines.

The rocker arms atop the cylinders are also unique to the Emerald.

Detail of the odd side-valve design of the starboard engine, another of the peculiarities of this wreck. The engines are mirror images of each other.

Back then many cargoes were shipped in barrels or smaller kegs. Here is the end of a small wooden keg, along with some staves. I can make out the word "WHIT(E)". The vessel's cargo included small barrels of cheese, which survives to this day as a foul-smelling white goo if you are unlucky enough to find any!

Shipwreck Emerald
Here are the remains of a bigger barrel that once stood upright.
Butterflyfish
A late-year Butterflyfish.

A small lobster dug in under a piece of wreckage. There aren't too many on this site. The Emerald is known mainly as a digging wreck for artifact hunters.
