Truckable Tug

Naval architecture and marine engineering ? rm Elliott

Bay Design Group (EBDG) has partnered with Tacoma- based workboat builder Silverback Marine to design what it says is a compact yet mighty tugboat that can be trans- ported by truck over the road.

The truckable tug has an overall length of 25’ - 10 ?”, a beam of 14’ - 6” and a draft of 3’ - 4”. This vessel design offers a tug that can be easily transported to job sites with enough power and maneuverability to perform push-assists. “With 500 horsepower, the tug will produce a bollard pull over 12,500 pounds and has a still water range of 60 nautical miles pushing approximately 10,000 pounds at 4.1 knots,” EBDG said.

The design is available with either electric, hybrid, or outboard propulsion options and can be further custom- ized to ? t a speci? c operation. “This tug can be used in a ? eet as an alternative to a tradi- tional, larger vessel and offers ? exibility unavailable in standard designs. This vessel can be operated with a one-person crew and does not require compliance with United States Coast

Guard SubChapter M Regulations,” the company explained.

Haleakala

Matson’s new ? at-deck container barge was christened and launched during a ceremony at the Greenbrier Gunder- son Marine shipyard in Portland, Ore. on April 23, 2022.

The new barge, christened Haleakala, will be deployed in Matson’s Neighbor Island service in Hawaii starting this summer, connecting cargo to and from the U.S. West

Coast through its hub terminal in Honolulu.

With a carrying capacity of 620 TEU and room for 72 refrigerated containers, the new Haleakala is double the

Matson size of the older barge it is replacing and will increase the ef? ciency of Matson’s service to the neighbor islands. At 17.3 feet and capacity of more than 12,000 metric tons, it 362 feet long, 105 feet wide (beam), with a deep draft of will be Matson’s largest barge.
