Details

Hydraulic steering systems are now being used in every category of small vessel. In many respects hydraulic steering is preferable to mechanical steering. Hydraulic systems normally comprise of two main components, a steering wheel pump and steering cylinder(s). The steering wheel pump may be either a gear pump or a plunger pump. Whichever type is installed, steering is achieved by turning the steering wheel in either direction causing oil from the wheel pump to be supplied to the appropriate side of the cylinder. Oil is returned via the opposite side of the cylinder back to the pump.

The linear motion of the cylinder rod is transformed to a rotary motion by the tiller, which turns the rudder shaft and rudder. Check valves (non-return valves) are usually incorporated to prevent the rudder driving the steering wheel pump. If an autopilot is to be included in such a hydraulic steering system, then the oil flow providing the rudder movement must be controlled by electrical signals from the autopilot.

The RPU80 is recommended for cylinders between 80-250 cm3(4,9-15,2 cu. in.), RPU160 for cylinders between 160-550 cm3(9,8-33,5 cu.in.) and RPU300 for cylinders between 290 -960 cm3 (17,7-58,5 cu.in.).

Army Corps of Engineers Protects River Wildlife

A complex series of locks and dams up and down the Ohio River enable interstate commerce, travel and recreation by maintaining a usable pathway for watercraft, but come with the inevitable byproducts of disrupting the river’s natural systems. To combat this, the U.S. Army Corps of Engineers uses a complex monitoring and response technology designed to minimize the negative impacts of dredging on the river ecosystem. Steven Foster, a limnologist with the Corps Water Quality Team, works at the Robert C. Byrd Lock and Dam in Gallipolis Ferry, West Virginia. He said one key area he focuses on is the welfare of mussels in the river. River dredging can smother mussel beds, so Foster and the team of engineers monitor the beds to ensure their safety.

Researchers Track Glacial Meltwater On Its Surprising Journey

While the scientific community has formed its consensus on how ice sheets are shrinking in and around Greenland, some researchers are tracking what happens to the meltwater as it drains into the ocean each summer. Their study, published in Nature Geoscience by an interdisciplinary team of biologists, oceanographers and hydrologists, used computer models to simulate the meltwater to see where currents take it and what effect it could have on the ocean. Renato Castelao, one of the researchers and an associate professor of marine science for the University of Georgia, said one of the biggest discoveries of the study was the surprising final destinations of the ice sheets as they melt into the ocean each summer.

Ice Fishing With A SondeCAM Underwater Fishing Camera

Thinking of hitting the ice with a SondeCAM underwater fishing camera? Due to its rugged design, you won't have to worry about it handling the harsh elements. However there are a few simple tricks to get the most out of a FishSens SondeCAM while ice fishing. You won't have to do anything to modify the SondeCAM itself, but you are going to have to bring a few extra things. Most importantly we are going to need a power source. Unless you are hauling your gear with a truck, you'll want something more portable than the battery you used in the boat. Pick up an inexpensive and maintenance-free 12-volt, 9-amp battery. It is going to provide plenty of power, but will be much lighter and take up less space.
