delivery of a state-of-the-art survey vessel constructed by SeaArk of Monticello, Ark., the "J.H. Simpson." The new 42-foot aluminum boat will be used on the Middle Missis- sippi River and play a key role in the Corps' award-winning Bendway Weir Project. The new high-tech vessel utilizes satellite and sophisticated software not only to measure bottom depths, but river velocity and bottom sedi- ment content as well. The J.H. Simpson reportedly pro- duces 100,000 times more data than previously-used equipment. The survey boat is a 42-foot Dauntless Class vessel of all-welded aluminum, featuring a deep-V hull designed by C. Raymond Hunt As- sociates of Boston. Power is provided by twin 8V- 92TA Detroit Diesels, each produc- ing 500 hp. Electrical power comes from a 12.5-kW Onan generator. Both propulsion and generator systems use Fernstrom closed cool- ing systems to combat the increas- ing problem of Zebra Mussels block- ing cooling passages. Electronics, hydraulics and boom transducer arms were developed by Ross Laboratories, with SeaArk as the installation contractor. The J.H. Simpson did double duty recently during the Mississippi Riv- er flood, using its transducer chan- nel sweep system to survey breached levees, reportedly speeding up the repair process greatly.

Overcoming the suctions encountered alongside a ship and pulling off is easily ac- complished by the SWATH pilot. Directional stability, maneuver- ability and design that is becoming widely accepted as a stable opera- tional platform all combine to pro- duce a craft ideally suited to the rigors of pilotage, reflecting lessons learned over two decades of research and development.
