The NavGraphic revolutionized navigation by automatically plotting your exact GPS position on a real NOAA chart. It's like watching your boat's progress from an air- plane overhead. You can zoom in for precise maneuvering or zoom out for an overview of your entire voyage. Expert fishermen love it because the charts are complete with depth lines so they can follow bottom features looking for fish. Beginning navigators love it because there are no numbers to translate and no calculations to make. It's the most direct navigation tool ever developed. Now that revolutionary product is even better with a brighter, higher-contrast display in a new slim-line design. The new dis- play makes it easy to read under any lighting conditions and its new price makes it even more affordable. The NavGraphic XL—it's a whole new way to look at navigation.

Conoship International Delivers Specialized Chemical Tanker 'Marinor7 The 7,930-dwt chemical tanker M/T Marinor was recently delivered by Welgelegen Nieuwbouw en Reparatiebedrijf BV, Harlingen, The Netherlands, an associate shipyard of Groningen-based Conoship Inter- national BV, the joint marketing, sales, design and engineering force that represents 10 shipyards in the northern part of The Netherlands. The vessel will be trading with the Botany Bay Parcel Tankers pool under a long-term charter to carry clay slurry, used in the paper indus- try, and chemicals such as sulphuric acid on the U.S. and Canadian East Coasts. The tanker is 368.1 feet in length, has a 59-foot breadth and a draft of 24.6 feet. Her 20-man crew is ac- commodated in single cabins. The ship was specifically designed by Conoship to carry clay slurry in one direction and sulphuric acid on the return trip. Some of the factors taken into account were: the latest IMO/IBC type 2 vessel require- ments; the limited number of tanks; required trim and draft restrictions; and the nature of clay slurry and various chemicals. The Marinor's 12 cargo tanks, six for clay slurry and six for chemicals, all incorporate Avesta 2205 stainless steel, which combines high tensile strength with very good resistance against pitting from corrosive chemicals. The ves- sel is classified by Lloyd's Register. All cargo tanks are equipped with electric deep well pumps: Svanehoj DW 125/150 centrifugal pumps for the clay slurry tanks; and Svanehoj Bornemann E2 U6300 eccentric ro- tor deepwell pumps in the chemical tanks. A Cargomaster system from Skarpenord/Henri Systems allows cargo operations to be controlled and monitored from a central office situ- ated in front of the deck house, pro- viding an unobstructed view of the main deck. The ship's main propulsion plant consists of a non-reversible, four- stroke, in-line Krupp MaK 6M552 marine diesel engine with an output of4,050 kW at 500 rpm. This drives a four-bladed, highly-skewed, con- trollable pitch Berg propeller through a Lohmann & Stolterfoht reduction gear box, generating a top speed of 14.4 knots. Vessel maneu- verability is enhanced by a Holland Roerpropeller PD 265-1100 bowthruster with an output of 300 kW at 1,460 rpm. The following systems provide auxil- iary power for the vessel: three Caterpil- lar diesel generator sets rated at350kW each; one Van Kaick, 400-kW shaft gen- erator; and one Caterpillar emergency generator set rated at 65 kW. Three boilers are also installed for cargo tank heat generation.
