Technology Associates, Inc. (TAI) (, a New Orleans, LA based Maritime Solutions Company, has completed the contract for the Design and Construction of a high speed foil assisted hydrographic survey vessel.  The US Army Corps of Engineers (USACE) Baltimore District accepted delivery of the vessel on August 11, 2017.  The all-aluminum foil assisted catamaran has been named "S/V CATLETT" and measures 61’-4”length overall, 24 ft beam.  Designed to meet the USACE’s primary mission to conduct hydrographic surveys using sophisticated multibeam and single beam sonars

The hydrographic survey vessel was fabricated jointly at subcontractor Aluma Marine facilities in Harvey, LA. It meets the Lloyd’s Special Service Craft rules. It is equipped with a total 1,970 BHP MAN V8 propulsion engines which turn two Hamilton waterjets allowing for quick mobilization and response at high speeds in excess of 38 knots and survey speeds upto 10 knots.


The vessel's hydrographic survey capabilities features SONIC 2024 Multibeam sonars and single frequency sonars mounted inside a survey pod. The vessel has a galley, mess, and sleeping accommodations.

Mr. Anil Raj, President of TAI said; “This vessel Design and Build Program was delivered on budget and on schedule. The successful project performance resulted from the partnership spirit with which the USACE Marine Design Center (MDC), USACE Baltimore District and TAI who jointly managed and implemented the project. The Fabrication yard, Aluma Marine and the craftsmen who worked with and supported TAI personnel at the facility are to be commended. We are happy that the USACE received a custom craft suiting all of its requirements, and that the USACE is pleased with the craft’s performance, as well as the crew training provided under the contract. This is the first of three similar USACE contracts TAI has. The others are for USACE Norfolk and Mobile districts.”




The foil assisted catamaran system offers high speeds with minimal installed BHP and fuel consumption. This configuration with a 400 NM range and swift speed capability makes it a perfect application for near coastal and harbor patrol, interdiction, search and rescue. TAI has a patrol boat variant design for this
