Bahamas Receives New

RoPax Service

Ten years ago, a RoRo passenger ser- vice called Sealink, commenced in the

Bahamas — operating from Nassau to port of Governor's Harbor on the adja- cent island of Eleuthera. The vessel that performed this service was an aging 14- knot Greek ferry, which established a solid market within the RoRo sector.

Despite its healthy growth spurt, the venture ceased in 1993 resulting from rising repair costs and maintenance, specifically in the machinery depart- ment, as some engine parts had since been discontinued.

Then a group of local businessmen purchased an Australian RoPax catama- ran to re-enter the Eleuthera trade. This vessel, which incidentally is also named

Sealink, is from the Sea Transport Solu- tions (STS) design studio in Queens- land, Australia.

According to Craig Symonette, chairman of Bahamas Searoad, the shal- low draft and quadruple engines provide good access to shallow ports, but more importantly a redundancy coverage that their previous vessels didn't have.

While the selected one-year-old

Sealink was similar to the optimum ves- sel, the weather on the alternative route of Nassau to Abaco generated waves up to 10 ft. (3 m) at certain times. STS designed a modified high bow and gen- erated the CNC discs to facilitate the modification. The process of removing the old bow was undertaken by a local shipyard in Brisbane.

Boasting four MAN 14-liter, 390-shp diesels with 2.5:1 twin disc gearboxes, providing a service speed of 16 knots, the vessel also holds aluminum deck hatches above each engine room to facilitate a rapid engine change, while two generators supply 35 kva each.

The vessel can transport four trucks, 24 cars and 200 passengers, while its 50 ft. (15.2 m) wide deck allows cars to load first and drive up the portside, turn- ing around and facing aft on the star- board side. Sealink ran into its first experience with harsh weather condi- tions in April where it was caught in the middle of cyclone Neil east of Fiji — experiencing 25-30 ft. waves — both the vessel and crew were unharmed.

HEAVY-DUTY SIGNALS BY^ENFRE^

Model S-120 Piston Horn

Chosen for use on aircraft carriers as well as commercial vessels over 200 meters in length, the S-120 utilizes an oscillating piston driven by 7-1/2 horse- power 3 phase 220/440 volt electric motor producing 143 dB and a funda- mental frequency of 94 Hz in 1/3 octave band at one meter.

Kahlenberg Signals were developed to withstand the pun- ishing use of commercial and military service. Their dura- bility has been demonstrated over decades of service on ocean-going vessels ranging from naval warships to com- mercial vessels. Military specifications have required extensive testing for many of these whistles and the accessories supplied with them, which have proven the exceptional qualities of Kahlenberg design and manufac- turing.
