Chesapeake

Chesapeake was the largest oyster dredge boat built on the Chesapeake Bay.
Type:
shipwreck, clam dredge, USA
Built:
1936, Johnson Marine Railway, Crittenden VA USA
Specs:
( 93 x 25 ft ) 113 gross tons
Sunk:
early 1980s, burned, no casualties
Depth:
She could pull four dredges at once and carry as much as 5,000 bushels of oysters.

Chesapeake was built very heavily with 6x9” oak frames and 3” thick Georgia yellow pine planking. Chesapeake worked on the Chesapeake Bay until 1979 when she was sold to a company in Cape May New Jersey to work the mackerel fishery.

The shallow round bottom and low straight bow must have been uncomfortable on the open ocean.

waves

Ocean waves are created by wind ( in unique instances, waves may also be created by earthquake, landslide, or other major disturbance, but that does not concern us here. ) The factors in the mechanics of wave creation are wind speed and duration, and fetch.

Fetch is the distance over which the wind acts on the water. The longer the fetch, the greater the wave-building action. Similarly, the greater the wind speed, the greater the wave-building action. Winds are named for the direction they blow from, not to. Therefore, a west wind blows out of the west, toward the east. Predicting wave heights based on wind conditions is even today extremely imprecise - the weather service still gets it wrong about half the time.
