Marine Architect To Develop and assist with the boat Hull Manufacturing

PROJECT BRIEF Phase 0 Feasibility Study Carbon Composite Hydrofoiling Passenger Ferry Background We are evaluating the feasibility of developing a next-generation hydrofoiling passenger ferry platform intended for commercial passenger transportation in coastal and island environments. Current vessels operating in this market segment are typically: • Approximately 40 ft length • Fiberglass (GRP) construction • Conventional planing or semi-displacement hulls • Internal combustion propulsion • Relatively heavy with significant fuel consumption The long-term objective is to develop a hydrofoiling vessel platform capable of significantly reducing operating costs, fuel consumption, and emissions while maintaining practical passenger carrying capacity and seaworthiness. As a first step, we require a feasibility study to establish: 1. Potential weight reduction achievable through advanced composite construction. 2. Impact of reduced vessel weight on hydrofoil performance. 3. Expected operational efficiency improvements. 4. Preliminary development and manufacturing cost estimates. 5. Future suitability for electric propulsion systems. The outcome of this study will be used to determine whether a detailed vessel design and prototype development program should proceed. Reference Vessel A representative 40 ft passenger ferry shall be used as the baseline vessel. Preferred reference: Gulf Craft Touring 40 Alternative vessels of similar dimensions and operational profile may be proposed if more suitable design data is available. The naval architect may source geometry from: • Existing CAD libraries • Publicly available hull databases • Similar vessel references • Parametric hull generation tools The objective is to establish realistic engineering estimates rather than produce a class-approved final design. Scope of Work Task 1 – Baseline Vessel Assessment Develop a baseline model of a conventional fiberglass vessel including: • Principal dimensions • Hull form assumptions • Displacement estimate • Payload assumptions • Passenger capacity • Machinery assumptions • Fuel capacity assumptions Deliverables: • Vessel summary table • Weight breakdown • Displacement estimate • Assumptions register Task 2 – Structural Load Definition Determine the loading environment required for structural design. This should include: • Global hull bending loads • Slamming loads • Bottom impact loads • Local deck loads • Passenger loads • Hydrofoil attachment loads • Operational sea state assumptions • Safety factors Deliverables: • Design load document • Structural design criteria • Recommended certification standard references Examples: • ISO 12215 • DNV • Lloyd’s Register • ABS High Speed Craft • Other relevant standards Task 3 – Composite Weight Reduction Study Provide structural requirements and load cases that will enable a composite engineering team to develop: • Carbon fiber laminate schedule • Carbon/aramid hybrid concepts • Carbon/glass hybrid concepts • Core material selection • Impact protection strategy The naval architect shall work collaboratively with the composite engineering team. Expected outputs: • Target laminate performance requirements • Estimated structural panel requirements • Hull stiffness requirements • Hydrofoil reinforcement requirements The composite team will subsequently provide estimated laminate configurations and resulting structural weight. Deliverables: • Estimated fiberglass hull structural weight • Estimated carbon composite hull structural weight • Estimated carbon/aramid hybrid weight • Estimated weight savings percentage Task 4 – Hydrofoil Feasibility Analysis Evaluate the effect of reduced vessel weight on hydrofoil performance. Analysis should include: • Foil-borne operating mode • Transition to foil-borne operation • Required lift generation • Foil sizing assumptions • Stability considerations Deliverables: • Estimated foil-borne displacement • Hydrofoil sizing estimate • Lift-off speed estimate • Comparison with conventional fiberglass vessel Example output: Parameter Fiberglass Hull Carbon Hull Vessel Weight XX kg XX kg Lift-off Speed XX knots XX knots Required Power XX kW XX kW Task 5 – Performance & Fuel Efficiency Study Estimate operational benefits. The study should compare: Conventional Fiberglass Vessel • Existing operating speed • Fuel burn • Range • Cost per nautical mile Carbon Composite Hydrofoil Vessel • Operating speed • Fuel burn • Range • Cost per nautical mile Metrics requested: • Percentage fuel savings • Range increase • Emissions reduction • Operating cost reduction Sensitivity studies are encouraged. Deliverables: • Performance comparison tables • Fuel consumption analysis • Range analysis • Economic comparison Task 6 – Electric Propulsion Feasibility Provide a preliminary assessment of future electrification. Deliverables: • Estimated propulsion power requirements • Battery capacity estimates • Battery weight estimates • Practical operating range estimates • Key limitations and opportunities This section is intended as a preliminary engineering assessment only. Deliverables The final report should include: Report 1 – Feasibility Study • Executive summary • Baseline vessel definition • Weight analysis • Hydrofoil feasibility • Fuel efficiency analysis • Electric propulsion feasibility • Conclusions Report 2 – Engineering Data Package • Weight breakdown • Structural loading criteria • Hydrofoil assumptions • Design calculations • Input requirements for composite engineering Desired Candidate Profile We are seeking a Naval Architect with experience in one or more of: • High-speed craft • Hydrofoils • Composite vessels • Passenger ferries • Electric marine propulsion • Vessel performance simulation Experience with software such as: • Rhino Marine • Orca3D • Maxsurf • GHS • ShipConstructor • ANSYS AQWA • OpenFOAM • Similar marine design tools is preferred. Please provide: • Relevant project examples • Proposed methodology • Estimated timeline • Fixed-price quotation • Any assumptions or recommendations Expected Study Duration Target duration: 2 weeks depending on the depth of analysis proposed.
