1.2 Design and Attributes

i. Vessel Layout:

The vessel will be designed with layout shown as per the GA drawings.


The special layout for machinery, accommodation/mess room, control stations, etc is ergonomically optimized while the position of the each console center is located to give best pilot visibility and driving comfort for sustained operations.


ii. Hull Form:

The hull form is well proven and will be multi-chined, slightly deep-keeled, variable deadrise deep V high performance form with a fine forward entry, flared bow, wide chine flats and planing flats.


The bottom lines are semi-planing in form and will be rising up towards the stern in order to reduce buoyancy in the the transom and adjust LCG forward for high speed but flat, smooth and comfortable ride in rough seas.


iii. Attributes:

The vessel is designed to provide the following attributes:

  Superstructure with minimal windage drag/silhouette profile.

  A life span of 10 years, allowing for 1500 running hours of average annual usage with sustained operations of 10-12 hours/ day. 


iv. Operation Conditions:

The vessel is ability to operate in the following extreme tropical conditions:

• Ambient air temperature of up to 35 deg C. 

• Sea water temperature of up to 25 deg. C. 

• Relative humidity of up to 90% at 35 deg. C.


1.3 Compliance and Survey

The vessel is to be surveyed to latest Rules and Regulations for the Classification of RINA, notated as PC Hull 1 Mach, patrol, coastal navigation.


As such, the vessel will meet the requirements in the PC Hull 1 Mach, patrol, coastal navigation rules and shall comply with the requirements of main class for stability purposes of the RINA “Rules for the Classification of Ships”.


The Builder will appoint an approved Surveyor to carry out survey inspections during construction as per Survey requirements.


1.4 Quality and Control

The shipyard is accredited to ISO 9001:2008 which is certified by RINA and CCS, both are  members of International Association of Classification Societies (IACS).


1.5 Documents

The following documents will be used for the construction of the vessel:

• Design Document Package

• Vessel Specification Document

• Survey regulations as determined.

• Components suppliers documentation.

In the event the drawings differ from this specification, the specification will take precedence.

Three sets of drawings as per normal boat building practises will be supplied in English language upon the vessel completion corrected to ‘As Built’ as follows:

• General Arrangement Drawing

• Engine Room Arrangement

• Main Engine Shafting

• Ventilation Arrangement

• System Schematics

• Electrical Installation and Schematics



Three sets of the following reports will be provided in English language upon the vessel completion:

1.8 Weight Control

The builder is to be responsible for maintaining strict weight control throughout the project,with constant reference to the designer-supplied weight study. The builder is to advise the designer any items of equipment or fitout which are significantly different from the allowance made for in the weight estimate.

The builder will also weigh the following components/stages when completed and provide

the results of LCG/mass to the designer:

1. Completed Hull shell.

2. Completed Deck/Cabin shell.

3. Completed internal structure.

4. Completed Boat.

Depending on build process, these weight measurements may take the form of

additions/deductions from previous weights.

Weighings are to be completed on scales with a calibration certificate.


1.9 Owner Supplied Items

The following items are to be owner supplied and thus are not included in the scope of the builder’s supply:

· 2 x guns as per defined by shipowner, each mounted on forward weather deck and aft weather deck as stated in the GA drawings.

· Related components, cables, software, etc if applicable

These items, however are included in the full load or trials condition of the vessel and are
