Dongara Marine Delivers Ferry in Western Australia

Placing a board deck across two canoes, to make a broad flat and stable surface for transporting passengers and freight, was often done to form early ferries. The true catamaran is an evolution of that practical design concept. In recent decades, Australia has led in the development of all shapes and sizes for aluminum catamaran ferries.In December 2019, Dongara Marine of Port Denison delivered a very practical 148-seat, 24- by 5.5-meter ferry to Western Australia’s Public Transport Authority.

Repower of the Tug Gretchen H

As sometimes happens with boats in the maritime world, the recent repower of a tug shone a light on a pair of well known independent companies. The tug Gretchen H. (ex Harry Olsen, Polar Breeze) was built by Rodriguez Shipbuilding of Coden Alabama in 1997 and is currently owned, since 2005, by Boyer Towing.The Gretchen H is a good solid boat and her owners decided she was well worth a new set of engines. At 80 by 30 feet she has an eleven foot depth. As with many tugs out of the Rodriguez yard she has triple propellers and triple engines. She had an older set of engines rated at 700 HP each.

Triple-screw Tug for the Hudson

“The Daisy Mae is the closest you can get to Z-drive maneuverability, without the cost of Z-drive,” maintains her builder Joseph Rodriguez of Rodriguez Ship Building Inc. in Bayou LaBatre, Ala. Rodriguez has designed and built a lot of tugs over the years and doesn’t make this claim lightly. Further more he backs it up with his description of the beamy 82 by 32-foot tug that his yard delivered to Coeymans Marine Towing. This is one of the Carver group companies based at the Port of Coeymans 110 miles up the Columbia River from New York.
