Q3: What does "international standard" mean for this boat?

A: While it may not carry a specific regional certification like CE for all markets without formal assessment, it is constructed to key international norms for hull design, stability, flotation, and safety equipment installation. We use certified marine-grade materials (aluminum, ORCA fabric) and follow proven shipbuilding practices, ensuring it meets the high expectations of professional users worldwide. Specific certifications can be discussed as a custom project requirement.

Q4: Is the 200L fuel tank sufficient for full-day operations?

A:Yes, the 200L fuel tank is exceptionally large for a tender of this size. With a recommended 150HP engine, it provides a substantial operational range, allowing for multiple trips between the mothership and shore, or extended patrol/ work duties throughout the day without the need for refueling, which is crucial for operational efficiency.

Q5: How does the aluminum hull handle corrosion in saltwater?

A: The hull is made from marine-grade aluminum alloys (5052 & 5083), which are inherently highly resistant to saltwater corrosion. Combined with proper marine paint systems and sacrificial anodes, this hull offers exceptional longevity and minimal maintenance compared to other materials, which is why it comes with a 5-year structural warranty.

Q6: Can you customize the boat for specific commercial uses, like dive support or patrol?

A: Yes, full customization is a core service. For dive support, we can integrate tank racks, dive ladders, and freshwater showers. For patrol duties, we can install LED light bars, sirens, communications equipment mounts, and heavy-duty fendering. The spacious deck and durable construction make it an ideal platform for adaptation.

▋Operation & Maintenance- Liya 23 Foot Aluminum Hull RIB With ISO

I. Fundamental Safety Operating Principles

1. Pre-Departure Safety Check

Conduct a thorough inspection before every voyage. Verify the integrity of the aluminum hull for any signs of impact damage or deformation. Ensure all safety equipment is onboard, functional, and readily accessible: this includes at least one approved personal flotation device (PFD) for every person, a throwable flotation device, a fire extinguisher, visual distress signals, a sound-producing device (horn/whistle), a first-aid kit, and a fully charged VHF marine radio. Check the fuel level and ensure there are no leaks in the fuel system. Confirm the bilge pump is operational and the automatic deck drain is unobstructed.

2. Crew and Load Management

This boat has a maximum capacity of 14 persons or a weight limit as specified on the capacity plate (consult your specific boat's certification). Never exceed these limits.

Professional use often involves carrying gear; ensure all cargo is securely stowed and distributed evenly to maintain boat stability and optimal trim. A sudden shift of unsecured heavy gear can be hazardous.

3. Engine and Navigation Safety

• Kill Cord (Engine Cut-Off Lanyard): This is a critical lifesaving device. The helmsman must securely attach the kill cord to their person before starting the engine and at all times while underway. It ensures the engine stops if the helmsman is displaced from the console.

• Weather and Sea State Awareness: Always check the marine weather forecast before departure. The aluminum hull is light and strong but can transmit more shock in choppy seas. Adjust speed and course accordingly to ensure a safe and comfortable ride. Avoid operating in conditions beyond the boat's or crew's capability.

• Professional Vigilance: During port operations, patrols, or utility work, maintain a constant 360-degree lookout. Be especially mindful of swimmers, divers, smaller craft, and large commercial boat traffic and wakes. Use the VHF radio to communicate intentions and monitor channel.

III. Operational Handling for the Professional Aluminum Hull

The combination of a lightweight aluminum hull and high horsepower requires skilled handling for safe and efficient operation.

1. High-Performance Handling Characteristics

The 150-200 HP engine provides powerful acceleration. Apply throttle smoothly to avoid sudden jolts to passengers and gear. The V-shaped aluminum hull will plane efficiently. When on plane, the boat will offer a stable and responsive ride. However, in following seas or during high-speed turns, be aware of the hull's inertia.

2. Specific Maneuvering Techniques

Docking and Close-Quarters Handling: Use brief, gentle bursts of throttle when maneuvering at low speeds. The boat may be affected by wind due to its higher freeboard; plan maneuvers accordingly. Always approach docks or other boats at a controlled, slow speed.

Operating in Waves: When facing head seas, reduce speed to minimize pounding and stress on the hull structure. Take waves at a slight angle if necessary. In a following sea, maintain enough speed to keep steerage way but be cautious of surfing down waves, which can lead to a loss of control. The spacious anti-slip deck provides secure footing, but crew should always hold on.

Man Overboard Recovery: Immediately shout "Man Overboard!" to alert all crew. Assign one crew member to keep continuous visual contact with the person in the water. Execute a quick-turn maneuver to approach the person from downwind or down-current, coming to a stop with the person alongside the boat, not astern where they could be drawn into the propeller. Use the swim platform or boarding ladder for recovery.

IV. Comprehensive Maintenance Schedule

1. After Each Use (Post-Operation)

• Flush the Engine: If used in saltwater or brackish water, connect a freshwater flushing system to the outboard engine and run it as per the manufacturer's instructions to remove corrosive salts from the cooling passages.

• Rinse the boat: Thoroughly rinse the entire boat, including the aluminum hull, inflatable tubes, anti-slip deck, and console, with fresh water. This removes salt, sand, and debris.

• Clean the Deck: Wash the spacious anti-slip deck. If optional PVC flooring is installed, clean it with appropriate products to maintain its condition and slip resistance.

• Dry and Ventilate: Wipe down surfaces and leave hatches or storage compartments open to air out and prevent mildew.

• Check for Damage: Perform a visual inspection of the aluminum hull for new dents or cracks, and check the tubes for any signs of chafing or abrasion.

2. Weekly / 50-Hour Maintenance

• Engine Check: Check the engine oil level and condition. Inspect the propeller for nicks, dents, or fishing line entanglement.

• Electrical Systems: Test all navigation lights, the console instruments, the bilge pump (by activating the float switch manually), and the horn.

• Safety Gear Check: Verify that all required safety equipment is present and in good order. Check the pressure gauge on fire extinguishers.

3. Seasonal or 100-Hour / Annual Maintenance

• Engine Service: Follow the outboard engine manufacturer's recommended service schedule meticulously. This typically includes changing engine oil and gear lube, replacing spark plugs and fuel filters, and inspecting the water pump impeller. This is best performed by a qualified marine technician.

• Hull and Structure Inspection: Conduct a detailed inspection of the aluminum hull, paying close attention to welds, rivets (if applicable), and structural members for any signs of stress, corrosion, or cracking. Inspect the transom for integrity where the engine is mounted.

• Corrosion Prevention: Inspect all metal fittings, fasteners, and the steering system for galvanic corrosion. Apply a marine-grade anti-corrosive lubricant as needed.

• Tube and Inflation Check: Check the inflation pressure of the inflatable tubes when the boat is at a stable, cool temperature. Inspect the fabric and seams thoroughly for UV degradation or damage. Professional tubes may require specific adhesives or repair techniques.

• Battery Care: Check the charge of the starting battery and clean the terminals. Ensure battery is securely mounted.
