I find it hard to believe that a 34' offshore style boat with triple 300 Mercs can operate effectively in 12" of water. Then factor in the armored hull, associated load out.....OH and don't forget the 6 MG's. That's right they need 6 M240B's on the boat.
The link has a video of it.
The solution is a new weapon aimed to stop smugglers and criminals before they reach Texas' shores. At 34-feet long, powered by three 300 horsepower engines and armed with six machine guns, the "JD Davis" resembles a military patrol boat.
The $580,000 shallow water interceptor can patrol in just 12 inches of water and is the first of a planned fleet of six such vessels comprising the newly-created Highway Patrol Tactical Marine Unit.
Each vessel will be named after a DPS trooper killed in the line of duty. Jerry Don Davis was shot and killed in 1980, and the first cruise of his namesake vessel was taken by members of his family.
