Incat Crowther 26m catamarans delivered by Cheoy Lee
Cheoy Lee Shipyards has delivered two Incat Crowther 26m catamarans to Penguin International in Singapore. The Hong Kong based company reports that the vessels, Penguin 32 and Penguin 33, are a development of two Crowther Design 26m catamarans delivered to a local operator in 2004, the year before Incat Designs and Crowther Design merged to establish Incat Crowther.
The four vessels were built at Cheoy Lee's production facility, the Hin Lee (Zhuhai) Shipyard in Doumen, Guangdong Province, China. All have the same overall dimensions but the latest two have been modified to meet the requirements of the International Maritime Organization's High Speed Craft Code 2000.
The company reports, "Although Cheoy Lee has previously built commercial vessels to comply with this code, these were our first aluminium catamarans to do so.
"Damage stability requirements are particularly tough and the Penguin vessels are fitted with double bottoms and buoyancy tanks over much of their length in order to comply.
"Each vessel is subdivided up into no fewer than 16 watertight compartments and is able to withstand a breech of the hull extending over half of its length, yet still remain afloat and not heel more than 10o as a result.”
Incat Crowther adds, "These are the smallest HSC Code vessels that Incat Crowther have designed, providing an efficient alternative to the standard series of large HSC craft currently in the market.
"This size vessel provides a highly efficient means of transportation for a small HSC compliant vessel. When compared with standard 450 passenger, 38 knot high speed ferries, this vessel has a fuel efficiency per passenger mile half that of the larger vessel."
Like the earlier 26m catamarans, Penguin's vessels have two Cummins KTA 38-M2 diesels, rated at 1,007 kW at 1,900 rpm, powering Nibral class 'S' fixed pitch propellers via ZF 4540 gearboxes. Cheoy Lee comments, "The vessels run at 27 knots with a full complement of 200 passengers, six crew and 6,000 litres of fuel."
Auxiliary power is provided by two Perkins 4.4 TWGM generators coupled to Stamford UCM224F alternators. Each set produces 46 kW of 3-phase, 415v, 50hz AC power and is able to support all onboard power loads, including the air conditioning system.
The main deck saloon is fitted out with 152 Beurteaux Ocean Traveller seats; a kiosk, luggage racks and two wheelchair spaces grouped around a staircase to the upper deck; and three toilets aft. There are another 48 Ocean Traveller seats in the upper passenger saloon and one toilet that is accessed from the aft deck. Also located aft of the saloon is a four berth crew cabin.
