Operation & Maintenance- Liya 22FT Sport RIB Boat With Outboard Engine
After each use: Rinse the engine, hull, deck, and fenders with fresh water to remove salt. Wipe all mats.
Regular inspections (every 50 hours/week): Check fender pressure and visually inspect for wear or UV damage. Inspect the hull for scratches and test the bilge pumps.
Annual/seasonal maintenance: Perform a full overhaul of the outboard motors as recommended by the manufacturer. Consider a professional inspection of the 200-liter fuel tank. Clean and disinfect the 80-liter freshwater system (if equipped). Clean and wax the hull to protect the gelcoat.
Storage: For long-term storage, place the boat on evenly supported supports, drain the freshwater system, and consider using a boat cover.
I. Safety Operation Procedures
1. Pre-Departure Systems Check and Passenger Briefing
A comprehensive pre-launch check is non-negotiable. Begin with a visual inspection of the fiberglass hull for any new impact marks or stress points, especially along the keel and near the integrated swim platform. Verify the inflation pressure and integrity of all tube chambers.
Check the 200L fuel tank level and the 80L freshwater tank, ensuring filler caps are secure. Test all electronic systems: navigation lights (including any on the T-top), VHF radio, chartplotter, and the automatic bilge pump. Confirm that the fire extinguisher is charged and readily accessible.
Before departing, conduct a mandatory safety briefing for all passengers. Clearly indicate the location of life jackets, throwable flotation devices, first-aid kit, and engine cut-off switch. Explain basic rules: no standing while underway, holding onto secure grabs during acceleration, and keeping limbs within the cockpit area.
2. Core Operational Principles and the "Kill Switch"
The fundamental rule of operation is the unwavering use of the engine cut-off lanyard. In the event of a sudden maneuver or the helmsman being displaced, this is the single most critical feature for preventing a runaway boat. Furthermore, always operate at a speed appropriate for the conditions—sea state, visibility, and traffic density. The high horsepower available provides thrilling performance, but responsible use mandates that power be applied judiciously, especially with guests onboard who may be unfamiliar with the sensations of a high-performance RIB.
3. Handling the Convertible Luxury Layouts
A unique feature of this boat is its transformable bow and stern areas.
Crucial Safety Protocols for Layout Changes:
Secure Stowage for Conversion Kits: When the sun cushions or the sturdy fiberglass table are not in use, they must be securely stowed and fastened in their designated storage areas to prevent them from becoming hazardous projectiles in choppy seas.
Stability Assessment: When configured with the fiberglass table in place, be mindful that it may slightly alter the boat's center of gravity. Avoid sharp, high-speed turns in this configuration until you are familiar with the boat's handling characteristics.
Sun cushion Configuration: In the lie-flat sun cushion mode, ensure all passengers using them are aware the boat is not in motion. Never allow passengers to lie on the sun cushions while the boat is underway.Transition to and from this configuration should only be done when the boat is securely stopped, engine off, and in calm water.
Swim Platform Use: The luxurious rear swim platform is for use only when the engine is completely shut off and the key is removed. Establish and enforce a clear rule that no one is to approach the swim platform until the helmsman announces it is safe to do so.
4. Performance Handling with High Horsepower
The potential for engines from 150 to 250HP means this RIB can achieve exceptional speeds and rapid planing. Apply throttle smoothly and progressively to bring the hull onto plane, ensuring all passengers are braced. Once on plane, the fiberglass hull will offer a firm, stable ride.
Be acutely aware of sea conditions: in a head sea, reduce speed to prevent the hull from "pounding," which is stressful for both structure and passengers. In a following sea, maintain control to avoid "broaching" (swinging sideways). The adjustable helm seat allows you to find the perfect position for optimal control and visibility—use this to your advantage for long journeys. Remember, the boat's responsiveness is a function of its power; your inputs at the wheel and throttle should be deliberate and measured.
II. Comprehensive Maintenance Schedule
1. After Every Use (Essential Post-Operation Care)
Immediate care is the cornerstone of longevity. Flush the outboard engine meticulously with fresh water using a proper flushing attachment to eliminate corrosive salt deposits from the cooling system. Rinse the entire boat with fresh water, focusing on the Hypalon/PVC tubes, the fiberglass hull (including the swim platform), and the deck. Remove any debris from the deck drains to ensure automatic drainage. Wipe down all upholstery on the adjustable helm seat and any convertible cushions with a damp, fresh-water cloth to remove salt and sunscreen residues. Rinse the freshwater system's deck shower or sink outlet (if used). Leave storage lockers and hatches slightly ajar to promote ventilation and prevent mildew.
2. Weekly or 50-Hour Interval Maintenance
Conduct a more detailed inspection. Check and adjust tube inflation pressure to the manufacturer's specification when the boat is in a cool, shaded environment. Perform a close visual inspection of the tube material for signs of UV fading, chafing, or abrasion against the hull. Inspect the fiberglass hull for any new gelcoat scratches, cracks, or stress marks. Operationally test the bilge pump by adding a small amount of water to the bilge. Inspect all through-hull fittings for the fuel and water systems, ensuring they are tight and leak-free. Examine the steering system for smooth, unrestricted movement and check the hydraulic lines or cables for wear. Verify the tightness of all railings, cleats, and the swim platform supports.
3. Seasonal or 100-Hour/Annual Service
This involves in-depth servicing best performed by or in consultation with marine professionals.
Engine: Adhere strictly to the outboard engine manufacturer's service schedule for major items: changing engine oil and gear lubricant, replacing fuel filters, spark plugs, and inspecting/ replacing the water pump impeller.
Fuel System: Given the substantial 200L tank, consider a full inspection of the fuel tank, vent lines, and fuel/water separator. Stabilize fuel if the boat will be idle for extended periods.
Freshwater System: Sanitize the 80L freshwater tank and lines with a marine-grade sanitizing solution to prevent bacterial growth. Drain it completely if freezing temperatures are anticipated.
Structural and Cosmetic: Detail clean the fiberglass hull and apply a high-quality wax or polymer sealant to protect the gelcoat. Deep clean the Hypalon/PVC tubes with a dedicated cleaner and apply a UV protectant formulated for the material. Inspect all sewn seams on convertible cushions and canopy for thread integrity.
Electrical: Check the battery's charge state and specific gravity. Clean all terminal connections and apply a corrosion inhibitor. Test the functionality of every electrical circuit and switch.
4. Winterization or Long-Term Storage Preparation
For extended non-use, thorough preparation is critical. Completely fill the fuel tank (to prevent condensation) using a fuel stabilizer, or drain it entirely. Flush and drain the entire 80L freshwater system. Remove the battery, clean it, and store it connected to a smart maintenance charger.
Deflate the tubes slightly (to about 80% of normal pressure) to relieve constant tension on the fabric and seams. Store all convertible components—sun cushions, fiberglass table—in a clean, dry, and temperature-stable environment. Support the hull properly on a trailer or cradle, and cover the entire boat with a breathable, soft-lined cover to protect it from dust and UV exposure while allowing moisture to escape.
