NAVATEK I

SWATH Excursion Vessel

Navatek Ships

One of the world's most unique vessels, the 140-foot Navatek I, the first U.S. commercial SWATH (Small-Waterplane Area Twin-

Hull) vessel, began carrying passen- gers on luxury Hawaiian dinner cruises in the first half of 1990.

Certified by the U.S. Coast Guard to carry as many as 400 passengers on an ocean route, the Navatek I is the first SWATH in the world to be classed by ABS, +A1 Ferry, Ha- waiian interisland service, +AMS.

A SWATH ship is designed to radically reduce ship motions— pitch, heave and roll—caused by waves. The SWATH ship's most unique market advantage is the vir- tual elimination of seasickness.

Compared to a conventional mono- hull or catamaran, it also offers greater maneuverability, more usa- ble deck space, and can maintain greater speed through rough waters.

According to Navatek Ships, Ltd., which designed and built the

SWATH ship, in her first seven months of commercial service, the

Navatek I has carried over 55,000 passengers. Despite operating in rough ocean seas of 4-12 feet all year long, the passenger seasickness rate has been less than 1 percent. Since the start of service, the Navatek I has not lost any operating days due to mechanical failure, seas or weath- er. "We're extremely happy with the response of tour wholesalers and customers to the product," said

John Pyles, president of Hawaiian

Cruises, Ltd., which operates the

Navatek I under a long-term lease on whale watch, luxury dinner, gourmet lunch and private charter cruises.

Navatek I is 140 feet long, has a beam of 53 feet, displacement of about 365 tons, and variable draft ranging from 8 to 12 feet. She is powered by two Deutz MWM 16V- 816CR diesel engines, rated at 1,350 hp each, fitted with Ulstein reduc- tion gears driving Ulstein controlla- ble-pitch, four-bladed propellers.

Auxiliary power is provided by two

GM 6-71-powered generators rated at 99 kw each.

The structural design of the ves- sel consists of two demi-hulls, con- nected by a cross-structure consist- ing of two box beams. There are two vertical struts per side which con-

LADY EXPRESS

Passenger Ferry

Munson Manufacturing

The summer of 1990 saw the de- livery of the 65-foot passenger ferry

Lady Express by Munson Manufac- turing to the Lake Chelan Boat

Company of Chelan, Wash.

Based on Munson Manufactur- ing's Hammerhead 65 design, the

Lady Express serves the town of

Steheikin, located 57 miles up lake from Chelan. She has a beam of 21 feet and draft of 5 feet. The design of the Lady Express features a com- fortable enclosed deck with an open covered area aft and an open back upper deck followed by a large open deck. There is seating for 70 passen- gers outside and 80 passengers in- side. Ample space is also available for luggage. She has a snack bar inside and men's and women's rest- rooms.

Great care was taken to protect the lake from the wake of the new vessel while maintaining quick and efficient transportation for passen- gers. The vessel was constructed to be partially assembled at the lake due to the problems involved with transporting a 65-foot boat via the interstate.

Ropes used for docking, anchoring, mooring, towing, fishing, heavy marine or recreational marine should offer excellent value with outstanding wet performance.

Generally nylon and polyester ropes perform poorly when wet. There is a loss of strength and a significant loss of abrasion resistance.

Allied Fibers, Allied-Signal Inc. devel- oped a proprietary marine overfinish for the cordage industry. It is available exclusively on Allied Fibers advanced products -- Caprolarf2000" Nylon and Advanced Performance A.C.E.

Polyester.

Select ropes with the SeaGard over- finish — they resist the damaging effects of salt as well as fresh water and offer maximum strength in the water -- where you need it most.

For further information and test results on how SeaGard benefits rope/cordage, please contact: your local rope manu- facturer or E.B. Clark, Allied Fibers, 1411 Broadway, New York, NY 10018.
