High-speed ferries need powerful engines day-in and day-out With high-transit networks converging on both sides, ferries built for high-speed travel must be well-built, stout and powerful. As a super volume commuter service for tourism operations, the vessel layout, speed, seakeeping ability and interior must be optimized for the mission. Such is the case of M/V Grey Lady IV, a 151-foot aluminum catamaran ferry built by Gladding-Hearn Shipbuilding in 2016. Operated by Hy-Line Cruises, she plies the waters of Nantucket Sound throughout the year.

QSB6.7 propels interdiction vessel Somewhere, just over the horizon, an interdiction vessel is apprehending another criminal enterprise at sea. A great chase begins, frequently ending with Coast Guard Cowboys literally jumping from their rigid-hulled inflatable boat (RHIB) onto some partially submerged submarine, forcing open the hatch for takeover.

Enforcing the law doesn’t just happen on land; it is also essential at sea. With record interdiction using tough, lightweight aluminum patrol boats, the success of the National Security Cutter program at apprehending criminals is remarkable. The 11M Long Range Interceptor II is just such a vessel, designed to pursue high-speed target craft for vessel board and seizure, rescue, and recovery.

With the regulated catch quotas of contemporary fisheries, design versatility for a fishing boat can be important. A new 19.81 by 7.31-meter (65X24-foot) combination crab trap and groundfish trawler designed by NAVANEX for building by Chantier Naval Forillon, both of Gaspé, Quebec, Canada is a fine example of this. Owners, Listuguj Mi’gmaq Government, anticipate accepting delivery in April of 2022.
