This wreck is also known as the Coconut Wreck. She was a four-masted schooner, launched as the Myrtle Sawyer, on November 24, 1904, in Millbridge, Maine, by the Warren Sawyer Co. She weighed 1,498 gross tons, was 224.8 feet long and 42 feet wide. A year later she was abandoned in an easterly gale and towed to Savannah. Many years later she was renamed Forest City. In 1916, the ship caught fire while in San Juan where her hulk was sold, rebuilt and renamed, Charles E. Dunlap.

On July 22, 1919, on her first voyage as the Charles E. Dunlap, while trying to enter New York harbor ending her voyage from San Juan, Captain Richard Crapsey lost his bearings due to a heavy fog and ran aground on Rockaway Shoal. Although there were calm seas, the Dunlap was unable to be saved. She remained on Rockaway Shoal until she broke up.

The Dunlap was carrying a cargo of coconuts during her last voyage, hence the name Coconut Wreck.

Regulators - First Stages

regulator

First stages come in several forms. Your main options are generally:

balanced or unbalanced
piston or diaphragm
sealed or unsealed

Manufacturers will try to make a big deal out of these and various other features. Here's what I think:

balanced or unbalanced - Today only the very cheapest regs are unbalanced designs. Breathing performance will suffer, and any reg that cheap will likely be deficient in other areas. There is no reason to buy an unbalanced first stage.
piston or diaphragm - This doesn't much matter, there are good designs that use both systems - worry about other things.
sealed or unsealed - This refers to whether or not water can enter the first stage. If water can enter, then so can sand and grit, which will inevitably cause a malfunction, probably while you are in the water. Also, for cold-water diving ( not ice diving, just cold water, say 45°F ), the water inside the first stage could actually freeze, with the same result. Do not buy an unsealed regulator for use around here. In fact, don't buy one, period. Sealed designs are generally more expensive to buy and maintain, but it is worth the extra cost. Some regulators ( Genesis, Sherwood ) accomplish the same effect without technically being sealed. This is just as good, maybe better, because the design is simpler.
