vessel has every electronic aid and survey need close at hand. The main switchboard and distribution panel is low down under the dash panel. Victor Solomon from ENL in Auckland, says Knave has been equipped for precision hydrographic survey work on Canada's rugged marine eastern coast. He says the client knew exactly what he wanted, and that no expense was spared to equip her with double and even triple redundancy built into her electronics package. Basic navigation capability consists of a Furuno NavNet 3D radar/sounder/chartplotter system, with a grunty 1kW transom-mounted transducer. Additionally, incorporated into this package is a Furuno FA30 Automatic Identification System to alert her to, and identify, those vessels that might be of concern within her operating range. These AIS targets will appear on her radar and/or plotter screens, together with Automatic Radar Plotting Aid targets. A Maretron solid state heading sensor has been included to provide radar course up and north up, target lat/long, and radar/plotter overlay as required. This same sensor also provides heading data to the Furuno NavPilot 711 autopilot. A Maretron Weather Station provides environmental information. Similarly, as part of the network, there is a Toughbook laptop running the PC based charting program MaxSea Explorer, providing the user with a "second station" for information from and control of the network. Because much of the area she will be operating in is isolated, the onboard radio communications are an ICOM 504 VHF radio and 802 single sideband, each with appropriate antennas. Technical survey equipment onboard include a POS MV Wavemaster dynamic positioning and orientation unit providing data for attitude, heading, heave, position and velocity, and a Hemisphere 131 Differential GPS providing sub-600mm positioning information. All onboard data is directed through a multiplexer and sources can be selected through a system of rotary switches. By now we can start to see the true depth and capability of this vessel. While Knave is essentially a day boat, the crew will be working long hours and she is fitted with a KAB selfriding helm seat to reduce fatigue on the skipper. From this position the helmsman has excellent all round vision, with only a small area well aft of the beam, blocked by the heads. In saying this, the helmsman can still see all four corners of the vessel and the small blind spot is easily compensated for. Once underway and clear of the marina and channel restrictions, Knave quickly responds to the touch on the twin throttles and quickly registered a top end speed of 42 knots on the GPS. Drop the revs to her most economical service speed of 25 knots and she is consuming 70 litres an hour which gives a working range of 500nm. Knave is surprisingly nimble at speed and easy to control in the turns. She is easy to manoeuvre, even when turning and berthing within the tight confines of the work pontoon and mangroves. Clearly the distance between the main engines gives the twin-screw manoeuvrability a significant advantage for the Canadian waterways. She sits comfortably on her purpose built, Canadian approved, triple-axle alloy trailer. Her tow vehicle is a new Ford F550 Super Duty rated to 26,500lbs towing GVM, that connects to the trailer via a fifth wheel and turn table coupling which is quite common in the northern hemisphere, where it is used in preference to the rig feeder coupling. The breaking system and trailer components are all American, supplied by CM Equipment incorporating a Kodiak electric hydraulic ■ breaking system for six stainless steel disc breaks. specifications The stern view gives an indication of the boat's capabilities Length overall 10.4m Hull length 9.0m Beam 3.1m Construction 5083 marine grade alloy plate Displacement (light ship) 5500kg Power 2 x 250hp Yamaha 4-stroke Petrol 1720 litres Diesel 125 litres Water 240 litres Electronics ENL Designer Greg Shine Builder Bladerunner Boats Limited Built to MNZ SSM coastal and Australian 2B offshore CLEAR SURFACE PROTECTION NZ/EUROPE • www.nyalic.co.nz AUSTRALIA • www.nyalic.com.au USA • www.nyalic.com Nyalic® is a Registered Trademark of HBI Inc.
