Name: “Humber Callisto” Waterjets: Triple Hamilton Jet Model HJ362 Brief Location: United Kingdom Specifications

NAME: Humber Callisto LENGTH: 17.2 metres [LOA] BEAM: 4.6 metres DRAUGHT: 0.8 metres CONSTRUCTION: GRP DISPLACEMENT: 24 tonnes SPEED: 35 knots (full load) 32 knots (cruise) WATERJETS: “Humber Callisto”, the latest pilot in the Associated British Ports (ABP) Triple Hamilton Jet Model 362 Hull fleet, is at the forefront of pilot boat technology. From the designer WATERJET CONTROLS: of the 20m Discovery class vessels operated by the Dutch Pilot Hamilton Jet Type HSRC ENGINES: Association, the 17 metre Humber Callisto is the first pilot boat to Triple Scania DI 14, each employ triple Hamilton Waterjets (HJ362s) and the first in the UK with 447kW (600hp) @ 2100rpm an advanced double chine hull. DESIGNER: Camarc Ltd, Worthing, UK ABP Hull spent over three years researching Humber Estuary where each year pilots BUILDER: the Humber Callisto project. The double board over 25,000 ships bound for the ports Souter Marine, Isle of Wight, UK chine hull form was chosen following of Hull, Goole, Grimsby and Immingham. OPERATOR: Associated British Ports, Hull, UK extensive research and model testing, along Hamilton Jet DISTRIBUTOR: with inspection of larger Camarc designed Hamilton Jet (UK) Ltd pilot boats in The Netherlands which are East Grinstead, UK based on the same hull concept. The double chine hull system has a number of sea-keeping advantages, and according to the designers is well suited to waterjet propulsion. Triple waterjets were proposed for the Humber Callisto so that the vessel would still be operational should one engine be temporarily out of service, and to provide greater flexibility when it comes to operating speeds and fuel consumption. During trials, Humber Callisto proved her ability in this ABP Pilot Boat “Humber Callisto” regard, achieving 25 knots with just two of her three engines running. Columbia Bar Pilot Boat The Humber Callisto’s GRP hull is “Chinook” “Chinook” during rollover tests constructed to approval of Lloyd’s Special Service Craft Rules for structure and to the MCA Workboat Code of Practice as a pilot boat. Comfort levels for two crew and up to ten pilots has been improved with significant noise and vibration reduction measures. Noise levels inside the wheelhouse are kept below 75dBA. The high level of control required when boarding pilots onto moving ships was a major factor in the choice of Waterjet propulsion. The vessel operates in the busy Hamilton HM Series Waterjets Thrive in North West USA

Name: “Puget Sound” The latest pilot boat for the 54-member Puget Waterjets: Twin Hamilton Jet Model HM571 Sound Pilots Association (PSPA) is the culmination Location: Washington State, USA of six years of development and represents further steps forward in terms of design, propulsion and overall capabilities of a modern pilot boat. From day one the design team for the “Puget Sound” set Brief specific parameters and criteria, then developed the boat Specifications around these standards. Main OPERATOR: objectives were a boat that Puget Sound Pilots Association could operate in all conditions LENGTH: BEAM: and under a high workload, was 22.5 metres (LWL) 6.0 metres CONSTRUCTION: strong and agile, and was safe Foam-cored GRP and comfortable for the pilots. SPEED: Waterjets were seen as the 27 knots WATERJETS: best propulsion option, with Twin Hamilton Jet Model 571 twin Hamilton HM571 jets WATERJET CONTROLS: providing outstanding Hamilton Jet Type HYRC manoeuvrability, low ENGINES: maintenance and repair costs, Twin Caterpillar diesels model 3412, plus overall efficiency and safety. PSPA committee co-chair John Harris says it was a quick 780kW (1,050hp) @ 2300 rpm DESIGNERS: decision to choose waterjets over propellers once they had seen the Dutch pilot boats in Tim Nolan Marine Design, action. “For pilot transfer purposes, waterjets are a fantastic choice”, he says. Port Townsend WA, & Hagemarine, Seattle WA, USA The GRP hull was designed with a number of anti-pitch, anti-roll and anti-heeling features. BUILDER: These features, along with the low drag and manoeuvrability afforded by the waterjets, Nordlund Boat Co, Tacoma WA, USA allow the new vessel to operate safely at higher speeds and at a greater angle to a ship.

A special pilot boat is needed to operate in the extreme weather and turbulent sea conditions of the Columbia River Bar. Features integrated into the Camarc designed and Hamilton Jet powered Columbia Bar pilot boat “Chinook” improve its overall safety and operational abilities. Twin Hamilton Jet model HM651 waterjets and Detroit diesels safely with all crew and equipment intact. provide “Chinook” with the power, speed, safety and Carrying two crew and four pilots, Chinook has a range of manoeuvrability required in this modern pilot boat. 250 nautical miles at an operational speed of 25 knots. The Chinook’s hull, designed by Camarc and based on the very vessel’s bridge console has mirrored control stations to both successful Dutch pilot boats, has significant structural port and starboard, which improves operator visibility and reinforcement and an advanced foam fendering system to go control for close manoeuvring and in difficult sea conditions. with its double chine hull shape. The Columbia Bar pilot boat works in tandem with a Another important design feature of Chinook is its self-righting helicopter, and will generally take over pilot-delivery duties ability, allowing the vessel to survive a 360° rollover and return when the helicopter is unable to operate. 10 Dutch Pilot Boats Powered by Hamilton HM571 Waterjets

Name: “M.V. Discovery” Waterjets: Twin Hamilton Jet Model HM571 Location: The Netherlands Loodswezen, the Dutch Pilotage Organisation, is committed to waterjet propulsion, highlighted by its use of twin Hamilton HM571 waterjets in all 10 of its modern pilot boats. Following evaluation of the prototype ‘new generation’ 18.5 metre pilot “Voyager” in 1993, the Authority has since commissioned a further nine 21 metre high Brief speed/high tech pilot boats to give it the most modern fleet in the world. Specifications The Dutch pilot boats’ revolutionary rough sea conditions with swells up to 2.7m features, including use of waterjet and strong winds. Sea temperature is below OPERATOR: propulsion, are often used as the benchmark 13°C for much of the year and one of the Loodswezen – Dutch Pilotage Org. LENGTH: for new pilot boat projects around the main reasons waterjets were chosen was 20.95 metres (LOA) world. Their success has helped the safety and speed of recovery in the event BEAM: demonstrate the many advantages waterjets of a pilot overboard. In rough conditions 5.5 metres have over propellers in all pilot transfer the new pilot boats can maintain a speed of DRAUGHT: situations. 19 knots, 10 knots faster than the older 1.0 metres (static) propeller driven vessels in similar conditions. CONSTRUCTION: All the Dutch pilot boats are powered by Aluminium 980hp Deutz MWM engines and Hamilton Loodswezen operates out of eight locations DISPLACEMENT: HM571 waterjets. This combination, around The Netherlands, with about 550 33.0 tonnes together with the double chined aluminium pilots making over 100,000 boardings in a SPEED: 28 knots (operational) hull, give the vessels a top speed of over 30 year.
