Cheoy Lee Catamaran delivered to Hong Kong & Kowloon Ferry
Jun 14, 2010
The first of two Cheoy Lee 32m composite catamarans ordered by Hong Kong & Kowloon Ferry, Sea Superb, has arrived in Hong Kong from the builder's Hin Lee Shipyard in Doumen, China.
HKKF already operates three Crowther Design 28m catamarans that were built by Cheoy Lee during 1999-2003 and the same mould was used to fabricate the operator's two new vessels.
The hull bottom is single skin composite and the rest of the structure, including decks, bulkheads and superstructure is resin infused foam core composite.
Cheoy Lee reports, "An extension to 30m was simple, a 4m removable parallel midsection previously used to extend the mould from 24m to 28m was lengthened to 6 metres. An additional 2m was added to the stem after fabrication to improve trim and performance.
"Composite engineering was provided by Gurit in Australia in accordance with Det Norske Veritas scantling equirements and drawings were approved by DNV before being submitted to the Hong KongMarine Department."
Both the length overall and the length waterline of the new catamarans are 4.0m longer than HKKF's 28m vessels. Other dimensions are identical, as are the main engines.
The rating of the diesels in the second and third Crowther Design 28m catamarans was increased to give them a service speed of 25 knots and the installed power of the units in the Cheoy Lee 32m catamarans has again been increased, marginally, to give the vessels the same performance.
Two Cummins KTA 38-M2 engines rated at 1,007 kW at 1,900 rpm each power a four-bladed fixed pitch propeller via a ZF 4540 gearbox.
The 32m catamarans, the largest vessels in the HKKF fleet, will carry a maximum of 425 passengers, 14-36 more passengers than the company's three Crowther Design 28m catamarans.
The main deck saloon of Sea Strperb is fitted out with 221 seats plus two wheelchair positions and three cargo stowage areas adjacent to access ramps to port and starboard. On the upper deck, there is a 146 seat saloon and 58 external seats aft.
Passenger amenities are limited to three toilets at the rear of the main saloon as HKKF's three routes are relatively short, maximum journey times at a service speed of 25 knots are approximately 25 minutes.
HKKF has been operating between the Central district of Hong Kong Island and Lamrna Island since 1999 and replaced New World First Ferry on the route between Central and Peng Chau in 2008.
The company's fleet currently totals 12 vessels. In addition to the three Crowther Design 28m vessels, it operates three 18m catamarans and six 22m-28m monohulls. The service speeds of the conventional ferries, or 'ordinary ferries' as they are known in Hong Kong, is 15-24 knots.
HKKF's original two fast ferries are operated on the Central-Peng Chau route. They complete the crossing in about 25 minutes, the journey on the conventional ferries takes about 40 minutes. The fast ferry fare, HK$24.50 on Monday-Saturday or HK$36 on Sunday, is more than 90% higher than the 'ordinary ferry' fare.
The new Cheoy Lee 32m catamarans are expected to enter service between Central and Lamma Island. At present, there is no fast ferry alternative on HKKF's two Lamma Island routes, Central-Yung Shue Wan and Central-Sok Kwu Wh.
The Yung Shue Wan route is by far the busiest, HKKF schedules 31 return services' each day on Monday-Saturday and between 26 and 30 return services, according to demand, on Sunday. Journey times vary between 25 and 30 minutes depending on the vessel operating the service.
On the longer Central-Sok Kwu Wan route. 11 dailv return services are scheduled on Monday-Saturday and between 11 and 16 on Sunday. Journey times are 30-40' minutes.
Standard single fares on the Lamma Island routes are HK$14.50 and HK$17.70 or HK$20 and HK$25 on Sunday. Both routes will be eligible for subsidies when the next three year licences become effective in July 2011 if proposals published last month by Hong Kong's Transport Department are accepted by the government.
