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
Fishing Vessel Sinks Off Shetland Following Collision The Shetland Coastguard received a distress call from the fishing vessel Harvester, 73 miles South East of Sumburgh reporting that they were in need of urgent assistance following a collision with the supply vessel Strilmoey.

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.

Three Keyport personnel recently returned after completing a project supporting the National Marine Fisheries Services (NMFS). The technicians returned from 42 days in the Bering Sea and Bristol Bay
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.
