It follows the launch of six YT 802-class yard tugs between 2009 and 2011.
“This is an exciting milestone for this program, as the YT 808class tugs will replace tugs built-in 1964 through 1975,” said Mike Kosar, program manager of the Support Ships, Boats and Craft Program Office within Program Executive Office Ships (PEO Ships) at U.S. Naval Sea Systems Command. “With five more in the pipeline, we’re excited to get these tugs underway and operational.”
The YT 808 class will be used for towing and ship-handling duties for aircraft carriers, surface ships, submarines and barges. Acceptance trials for the initial tug in the series are scheduled for September, with delivery of the other five tugs planned for this fall through the fall of 2021, according to Dan Shimooka, principal assistant program manager of Service Craft and Seaborne Targets for PEO Ships.
The YT 808 is 90 feet long and 38 feet 3 inches wide, with a navigational draft of 16 feet 6 inches. The tug is powered by twin Caterpillar 3512E main engines, each delivering 1,810 horsepower, driving Schottel SRP 340 fixed-pitch z-drive thrusters. Bollard pull is estimated at 40 metric tons, with a top running speed of 12 knots.
The tug has two rows of cylindrical fendering and a lower course of “W” fenders at the bow, according to designer Robert Allan Ltd. (RAL) of Vancouver, British Columbia. The fire pump is capable of delivering 2,000 gallons per minute through a pair of monitors. The YT 808 also has a remote folding mast. Although it is a day boat, there are quarters for up to six crewmembers.

Piracy edges closer to home with wave of raids in southern Gulf
In the brief cellphone video recorded by a crewmember on the offshore supply vessel (OSV) Remas, the pirates walk back and forth on the deck of the ship, clenching their guns and using them to point as they order around the crew. Their faces are draped in clothing and bandanas.

Bay State brothers find industry niche by making old into new
Zero non-conformities is what you want to hear when the U.S. Coast Guard inspects your tugboat. Once you’ve prepared your vessel, the inspectors come aboard to peruse your paperwork. They ask you pointed questions, to which they expect straightforward answers. Perusal completed, they then scrutinize all of the related safety systems, from bilge to antennas — even the ship’s bell.

Advanced props, rudders provide new efficiencies below the waterline
It took a decade or two from the invention of the marine propeller in the 19th century for the technology to become widely accepted. Thereafter, adoption has been nearly universal, but progress toward improved efficiencies has come in fits and starts.
