- Type:
- shipwreck, barge
- Depth:
- 95 ft
This wreck seems to be one or more wooden barges, possibly garbage barges from the 1920s. There is an anchor in one spot near a machinery pile, and in other spots, the old walls rise perhaps 10 ft off the bottom. But otherwise, everything is pretty broken down. This forms many hiding holes for lobster and rock crabs, and there is one in almost every hole, and some quite large. The Sea Bass are also good-sized. Yellowish natural sponges and bottles are easy to find.

- Depth:

This is a fascinating big wreck of a wooden schooner barge. The broken stern is upended, forming a hollow pyramid that is full of fish. The sides and keel extend north from there to the bow, from which extends a chain which reaches to another much smaller wreck, which is known as the "Inshore Tug."

Human Vision Underwater
When light travels from a less-dense medium like air to a more-dense medium like water, the rays are refracted or bent towards the normal or perpendicular of the surface between the two mediums. In crude terms, light going from air to water will tend to be straightened, while light going from water to air will tend to be ... um ... crookeded. Confused yet? Take a look at the figure below.
In this figure, you can see the light rays traveling from an object in the water to your eyes, neglecting the effect of the flat glass lens of your mask. The blue lines trace the actual path of the light rays through the water and into the air, or conversely, through the air into the water - the direction really doesn't matter. As you can see, the rays are bent toward the perpendicular of the surface on the water side, and away from it on the air side.
