About Swiftships Yachts
Generations of Gulf‑Coast Craftsmanship
Swiftships traces its roots to 1942, when Fred Sewart founded Sewart Machine Works in Berwick, Louisiana, pioneering lightweight aluminum boats for U.S. military use. Rebranded as Swiftships in the late 1960s, the yard has since delivered more than 1,000 vessels from its Morgan City facilities, earning a reputation for robust engineering and on‑time delivery.
Client‑Driven Custom Design
While celebrated for defense contracts, Swiftships also undertakes bespoke yacht and expedition projects, offering steel or aluminum hulls, flexible interior plans, and long‑range systems tailored to each owner’s brief. Early design reviews with in‑house naval architects ensure that performance targets, draft limits, and space requirements are met before construction begins.
Standout Builds and Conversions
Notable leisure projects include the 118‑foot tri‑deck UH OH, the 65 m explorer concept co‑designed with Evan Marshall, and the 91 m conversion yacht Voyager, transformed from an offshore supply vessel into an ice‑class world cruiser. These milestones highlight Swiftships’ versatility and its ability to blend commercial‑grade strength with super‑yacht comfort.
Innovation and Future‑Ready Technology
Swiftships invests heavily in R&D, advancing autonomous vessel platforms, composite armor integration, and hybrid‑ready propulsion for reduced emissions. Continuous improvement in aluminum welding and weight management keeps the yard at the forefront of efficient, high‑speed hull construction.
