Inshore Barge/Tug

Type:
schooner barge & tugboat ?
Depth:
85 ft

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."

Whether this actually is the tug that was towing the barge, or just a coincidental sinking, is unknown. Using a chain for a tow line would be highly unusual. Perhaps the barge was anchored to ride out a storm, and the tug sank on top of its hook. It may not even be a tugboat - it might be named that simply because it is inshore of the Great Isaac.

Here is a description of recreational dive planning. The purpose here is to demonstrate basic dive planning and use of Dive Tables for non-divers who are interested in becoming certified but are worried about the complexities and math involved. Learning to use dive tables is usually the single most daunting classroom task for a student diver. It's really not all that hard.

The purpose of dive planning is to manage the Nitrogen gas that is absorbed into the tissues of your body while breathing air at higher-than-normal pressures underwater. If you absorb too much Nitrogen at depth and then ascend to normal atmospheric pressure, the gas will form bubbles in your blood and tissues. This is called Decompression Sickness, commonly known as "the bends." Decompression Sickness can vary in severity from barely noticeable to fatal, depending on your dive profile and other factors. The goal of no-decompression dive planning is to plan your dives in advance so that under no circumstances* can ascending to the surface result in Decompression Sickness.
