Manatee, fast and sleek and seeming to come out of nowhere, snugged up abreast of the pilot’s ladder on the hull of the 611-foot break-bulk ship Texas Enterprise. Capt. John Timmel, a 29-year veteran and senior pilot with the Tampa Bay Pilots Association, descended the ladder and stepped aboard the new pilot boat.
Built at Gladding-Hearn in Somerset, Mass., the 53-foot Manatee is the latest evolution of the C. Raymond Hunt Chesapeake-class, high-speed, deep-V hull design. Gladding-Hearn and Hunt have a design/build venture that dates back to the 1970's. The aluminum craft addresses three attributes sought in pilot boats the world over: speed, fuel efficiency and comfort.
Manatee is powered by dual Volvo Penta IPS 650MC propulsion pods driven by a pair of 503- hp Volvo Penta D11 diesels. “In a loaded condition, the power package gives the Manatee a 27-knot top speed,” said Peter Duclos, president of Gladding-Hearn.
Forward-facing twin counter rotating propellers, located ahead of the stem, allow the IPS pod system to pull the boat through undisturbed water. “It burns about 25 to 28 percent less fuel than conventional propeller drives,” Duclos said.

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.

IMO emissions report raises new concerns about methane slip
A recent report from the International Maritime Organization (IMO) reveals that global shipping emissions increased nearly 10 percent from 2012 to 2018, with the industry facing a growing challenge concerning methane slip.
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.

Analysis points to faulty loading, low ballast in Golden Ray rollover
While the salvage of the sunken vehicle carrier Golden Ray has been delayed for months due to COVID-19 and the hurricane season, analysis by the U.S. Coast Guard has determined a possible cause for the rollover: a combination of vehicles placed too high on the ship’s decks, and not enough ballast water gave the placement of the cargo.
Seastreak newcomer pushing through dip in demand

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.
