Wesmar, a U.S. manufacturer of sonar equipment, has introduced its new line of trawl sonar catch sensors. ‘They are the fastest and most powerful on the market,” said Dennis Soderberg, WESMAR’s Vice President of the Electronics Division. The Model CS20 WESMAR catch sensors work with the highly popular WESMAR TCS780 and TCS380 trawl sonar systems. Up to six catch sensors can be used on the cod end of a WESMAR system. Numbers 1-4 are compatible with other trawl systems. The catch sensors measure the fill rate of the trawl indicating when the code end is full so the catch can be hauled in at the appropriate time. Catch sensors eliminate the problems caused by overfilling the trawl and improve catch efficiency and quality. Known throughout the world for its innovative and advanced fishing sonar, WESMAR is no stranger to the needs of fishermen and has worked for several years to perfect a system that reliably measures the fill rate of the trawl and alerts the wheelhouse when the net is full, saving them thousands of dollars in potentially lost catch and/or damaged nets. Wesmar released several features that set their catch sensors apart from other eggs. They transmit at the highest power on the market. No signal delay. Once triggered the catch sensors send five signals, 5 seconds apart, alerting the wheelhouse instantly
By Larry Pearson Marine science is making great strides forward due in large measure to several new vessels that have delivered recently and others under construction Headlining this news is the Oscar Dyson, the first of four vessels loaded with scientific gear that the National Oceanic and Atmospheric Administration (NOAA) is having built at VT Halter Marine, Pascagoula, Miss. The first vessel was completed in September of 2004 and as the Oscar Dyson was being completed

Diesel technology specialists from Royston Australia completed a three-week overhaul of the engines of the P&O Southern Supporter while it was docked in Henderson Fremantle, Western Australia. The project required the eight-man Royston team to work 24 hours a day, seven-days a week to service and re-build the ship’s three Cat 3516 engines. This included a complete strip-down of the engines, replacing the main bearings, overhauling the cylinder heads
Rapp Hydema has been supplying deck machinery to research vessels since 1977, but this global market recently became especially significant for the group. In 2002, in what would be a watershed project, Rapp Hydema was chosen to outfit the NOAA Fishery Survey Vessel (FSV) Oscar Dyson class of vessels. The first four ships in the class were being constructed at VT Halter Marine Shipyard. “That NOAA research vessel contract provided us with excellent exposure
The State of Delaware Division of Fish & Wildlife took delivery of First State to replace its current Fisheries Research Vessel (FRV), a 100-year-old converted wooden sailboat. The new 62 ft. (19 m), designed by Nigel Gee & Associates, was built by Derecktor in aluminum with a hard chine hull. The resiliently-mounted pilot house provides low noise levels. Behind the house, the ample aft deck has been fitted with swinging A-Frame and cargo boom, net reel, trawl winches
The rising cost of diesel fuel can significantly cut into commercial fishing profits, especially with an inefficient engine. But Mazatlan businessman Jesus Loya realized a nearly $60,000 annual fuel savings after repowering one of his fishing vessels with a new Yanmar diesel. His 69' Rio Elota now stays at sea longer and benefits from fuel savings of over 15% with a Yanmar 6AYM-WST turbo-charged direct injection engine, Yanmar said.
