Dookyu Marine designs and builds custom fiberglass work boats (6–23 m) with robust FRP construction and modular layouts. Our in-house engineering and certified production let us tune hull geometry, deck plans, and powertrains for patrol, fishing, passenger, and utility roles. We follow ISO/CE frameworks with full-process quality control. This platform suits operators who value corrosion resistance, a smooth finish, low noise, and sound lifecycle economics.
FRP patrol boats combine quiet operation with laminates that resist corrosion in brackish and marine water. Options include enclosed cabins, shock-mitigating seating, and outboard or inboard diesel for fast response and balanced efficiency.
For short-haul routes and tourism, passenger craft offer a smooth ride and quiet interiors with bench or premium seating layouts. Gelcoat finishes, non-slip decks, and CE-compliant stability support safety and easy upkeep.
Utility and fishing boats include easy-clean decks, fish boxes or workbenches, and reinforced hardpoints for winches or davits. The modular deck converts quickly for survey or light cargo.
Tour operators can specify noise-damped cabins, panoramic windows, and optional hybrid propulsion for quieter eco-tours. Smooth surfaces simplify branding and daily turnaround.
Typical lengths span 6–23 m. Beam-to-length ratios are tuned for stability and planing efficiency. Capacity ranges from crew tenders to multi-deck passenger layouts without sacrificing ride quality.
Choose deep-V or moderate-V monohulls for speed and seakeeping. Catamarans maximize stability and deck area. Laminate schedules and stringers are engineered for dynamic loads and predictable handling.
Modular grids support quick changes between patrol, fishing, passenger, and rescue. Options include wheelhouses, open work decks, gear storage, seating modules, and mission-specific fixtures tied into through-hull reinforcement.
Outboards simplify service and minimize downtime for nearshore duties. Inboard diesel delivers protected drives, a lower center of gravity, and extended range for heavier payloads and continuous duty.
Battery-electric boats offer near-silent operation and zero local emissions in harbors and lakes. Hybrid systems extend range with generator support while maintaining readiness.
Fuel capacity, placement, and redundancy align with route profiles, payloads, and weather margins. Propeller pitch, gear ratios, and hull coatings are tuned for cruising efficiency and lower operating costs.
Marine-grade resins, core materials, and glass fabrics are specified to meet impact and stiffness targets. Controlled layup and vacuum-assisted methods deliver consistent strength-to-weight.
FRP resists corrosion and is easy to finish, reducing repaint cycles and galvanic concerns. Damping helps limit hull-borne noise and vibration for comfort and equipment life.
For heavy firefighting loads, high-impact work, or extreme thermal environments, aluminum or steel may be a better fit. Multi-material capability lets us provide objective guidance.
Designs follow ISO and CE frameworks with traceable materials, bond checks, and full-process inspections. Documentation supports flag and port requirements.
Add monitored bilge zones, fire-retardant materials, fixed fire systems, and search-and-rescue gear. Redundant power and communications support critical missions.
Wheelhouse layouts target 360° visibility, glare control, and ergonomic controls to limit operator strain. Anti-slip decks, handrails, and compliant stairs aid safe movement.
Select gelcoat colors, wraps, upholstery grades, and antimicrobial surfaces suited to your brand and climate. Durable finishes keep the vessel looking professional with minimal downtime.
Modules for patrol, fishing, passenger, or survey include mounts, livewells, benches, canopies, A-frames, and transducer bays. Structural inserts ensure safe load transfer into the hull.
Integrate radar, AIS, thermal cameras, and redundant networks on shock-isolated mounts. Power distribution and battery systems are engineered for reliability.
From concept and 3D modeling through laminate engineering, tooling, layup, outfitting, and commissioning, Dookyu Marine provides a single point of responsibility. Virtual reviews are available to track progress.
Every vessel undergoes dock tests, sea trials, and system calibrations to verify speed, handling, and safety. Crew training and documentation are included at handover.
We supply export-ready cradles, protective wrapping, logistics, and customs support. After-sales covers spare parts, remote assistance, and maintenance guidance for long-term uptime.
Compact deep-V, enclosed helm, twin outboards, and reinforced towing bits for harbor response. Tuned for quick acceleration and tight maneuvering.
Moderate-V hull with seating for 12–20, inboard diesel or twin outboards, and a weatherproof canopy. Designed for short-haul coastal and lake routes.
Spacious foredeck, crane foundation options, heavy-duty fendering, and extended fuel for full-day operations. Useful for resort supply, aquaculture, and light construction support.
Define routes, sea states, target speeds, and equipment weights to right-size hull, power, and deck plan. Payload envelopes maintain safety margins.
Balance purchase cost with fuel use, maintenance intervals, and resale value. FRP’s low corrosion and durable finishes help reduce lifetime upkeep.
Confirm local rule sets and inspection needs early. Our team aligns documentation and testing to the required standard.
Fiberglass stands out for clean finishes, low upkeep, and effective noise damping—well-suited to passenger comfort and frequent-turnaround operations. Where demands favor metals, we can recommend aluminum or steel.
Q: What lead times are typical?
A: Timing depends on size and customization. Smaller FRP boats can be delivered faster with streamlined tooling and layup. Early lock-in of modules and powertrains helps accelerate the build.
Q: How is maintenance handled?
A: Routine care includes hull washing, periodic antifouling, and system checks. Composite hulls avoid many corrosion treatments required by metals. We support parts supply, manuals, and remote assistance.
Q: Do you offer global delivery?
A: Yes. Vessels ship on export cradles with protective packaging and managed logistics, with documentation prepared for customs in major markets. Contact the fiberglass work boat manufacturer team at Dookyu Marine to discuss your route and request a quote.
