SINGAPORE Strategic Marine (S) Pte Ltd. has unveiled the Aluminium 42-m (138-ft) Gen 4 fast crew boat (FCB) design.

The vessel features a new hull form and Z-bow which are said to improve seakeeping, require less power for the same speed and deadweight (dwt), reducing fuel consumption and lower emissions.

The new hull form was developed in collaboration with Southerly Designs with CFD analysis and optimization by Seaspeed Marine Consulting. It has been put through comprehensive model testing at the Australian Maritime College to further verify and validate the performance predictions. These extensive test results confirm that the hull resistance is reduced by more than 8% compared to the Gen 3 hull form, the company said.

The new vessel also incorporates design enhancements based on feedback from operators, improving on the performance of the company’s Gen 3 design which was launched in 2014.

The new Gen 4 FCB is 42 m in length, with cargo carrying capacity of 190 dwt, a clear deck area of 140 sq m (1,507 sq ft), a cargo deck area of 120 sq m (1,292 sq ft), and a deck loading capacity of 2.5 metric tons/sq m. It has business class seating capacity for between 80 and 100 passengers with space for 12 crew in seven berths and one medical room/office.

The company said the wheelhouse has been increased in size for optimum comfort and visibility. Also, the main passenger super structure area has been fitted with maximum size windows with improved positioning to provide excellent passenger visibility, reducing motion sickness. 

An optional gyro stabilizer reduces the vessels rolling motion, increasing safety and efficiency during personnel transfers. The vessel can also be fitted with an autonomous control module for either local or remote autonomous operations.

The Gen 4 FCB can be fitted with three Cummins KTA 50 M2 engines, delivering clean and efficient power of 4,026 kw (5,400 hp). The vessel can deliver a service speed in excess of 30 knots at 85% MCR with a full speed of 32 knots at 100% MCR. The fuel consumption at service speed is about 827 liters/hr (three engines).

The Gen 4 FCB dimensions are:

• Length overall: 42 m

• Beam (max) molded: 8.20 m (27 ft)

• Depth molded: 3.75 m (12.3 ft)

• Hull baseline design draft: about 1.90 m (6.2 ft)

• Propeller draft max: about 2.10 m (6.9 ft)

• GRT (approx.): 317

• Max deadweight: 190 metric tons (increased from 105 metric tons)

• Clear deck area: 140 sq m (increased from 120 sq m)

• Cargo deck area: 120 sq m (increased from 100 sq m)

• Deck loading capacity: 2.5 metric tons/sq m (increased from 2.0 metric tons/sq m)

• Fuel oil: 84.2 cu m (2,973 cu ft)

• Fresh water: 33.0 cu m (1,165 cu ft)

• Black/grey water: 0.5 cu m (18 cu ft).

The Gen 4 FCB can be equipped with motion compensated gangway, deck crane, GYRO stabilizer, active ride control, SCR System for IMO tier III compliance, hybrid propulsion options, biosafe notation, twin bow thrusters, bow boarding, ballistic protection, DP-1, semi-autonomous control, and fire-fighting systems.

The vessel has achieved approval in principle with Lloyd’s Register, BV and RINA, but can be classed with any other IACS classification society, the company said.
