Rozema Boat Works ensured that the Northwest will be a vital part of US Coast Guard (USCG) readiness over the next five years when it was awarded an indefinite delivery, indefinite quantity (IDIQ) contract to provide new all-weather, heavy-surf workboats.
The IDIQ order commissions up to six new second-generation SPC-HWX II vessels for special-purpose missions. The muscular, aluminum-hulled vessels will be used for search and rescue, coastal security, and towing of disabled fishing vessels, said Tim Kolb, vice president of Rozema Boat Works, based in Mount Vernon, Washington.
“The previous generation these vessels are replacing were much older and had much less power,” Kolb said. “They were only 52-footers and had single-props.”
Most of the first-generation workboats were built in the 1950s and 1960s and were all retired by 2021, according to the USCG. All told, USCG said the contract with Rozema is expected to be worth $70.9 million.
The 64’ second-generation SPC-HMX II boats, designed by U.K.-based naval architecture firm Carmac Design, will feature twin props made for extreme-weather operations. Elliott Bay Design Group of Seattle will provide engineering services and technical data compliance.
Fitted with twin MAN 1,200-hp diesel engines, the new SPC-HWX II boats will have a bollard pull in excess of 18,000 pounds, reach top speeds of 20 knots, and operate up to 150 miles offshore. With an ability to self-right in seas of up to 35 feet, the vessels can operate safely in wind conditions topping out at 60 knots for 48-hour periods.
“The plan is for up to six vessels to be completed in the next five years,” Kolb said. “We expect the first one to be ready for delivery somewhere in the Pacific Northwest in the summer of 2027.”
