The “Lugger” designation traces back to days when a small handy coastal vessel often carried lug-rigged sails. A modern day lugger, as used on the US Gulf of Mexico coast, is still a handy boat for working in near shore waters. On a version of the tug, designed by and currently finishing up at Rodriguez Boat Builders, a pair of Cummins Tier 2 compliant QSK19-M diesels turning four-blade stainless steel props has replaced the lugsails for propulsion.

Military, State Orders Buoy Patrol Boat Market

By Larry Pearson Even before the events of 9/11, the patrol boat market for the Navy, Coast Guard and individual state law enforcement departments was very active. For example, in the 1980's Bollinger built 49 Island Class Patrol boats and 10 years later built 50 smaller patrol vessels also for the Coast Guard. These assets were immediately deployable to counter terrorism threats after 9/11. But with the entire nation on alert


Macro Sensors Gauge Tank Volume Changes

This diagram shows the LVDT level sensor attached to the side of a tank using a flat-hook assembly. The high-permeability core follows the position of the stainless-steel float. The LVDT electronics sense the core position using magnetic induction. Output is a 4 to 20-mA instrumentation current loop corresponding to the position of the core in the LVDT body.

Configured with a float, Macro Sensors HSIR Series LVDT Linear Position Transmitters are serving as level sensors to measure liquid level changes from a few inches to several feet in gauging tank level volumes. In this LVDT level sensor configuration, a stainless-steel float coupled to a nonmagnetic stainless-steel rod is attached to the high-permeability, armature core of the LVDT. The 4 to 20-mA loop-powered LVDT position transmitter senses the position of the core and, therefore
