Rigdon took the Guido Perla and

Associates design of a diesel-electric

PSV with DP-2 certification and a streamlined hull for fuel efficiency, able to produce a top speed of 13 knots fully loaded and 15 knots in light conditions, and shopped it to shipyards, with Bender

Shipbuilding of Mobile, Ala., winning the contract. As for the future, Rigdon envisions additional consolidation, but not necessarily in the form of complete corporate takeovers. He believes there will be more loose affiliations between companies in an effort to share costs, and while he admits his company is engaged in conversations along these lines, he was not ready to share details.

To build and grow the business,

Rigdon has invested in people as well as boats, hand selecting his key executive staff, which consists mainly of young, technically competent people, to build a solid foundation for the company's growth and long-term future.
