Lugger Tug from Alabama Yard

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. The 67.5 by 26-foot Pere C. has a molded depth of 8.5 feet.

Military, State Orders Buoy Patrol Boat Market

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, it was obvious that the more sets of eyes and ears we could put on our 95,000 mile coast line the more secure we would be. In the last two years, hundreds of smaller patrol boats have been built specifically to increase security around ports and other facilities across the nation. The Navy has been very active ordering vessels to patrol Navy bases and other military installations.
