Navigation Zero

Navigation Zero by ILIOFOS Industrial & Marine is the professional design tool for electric and hybrid boat propulsion — from the first estimate to the quotation you hand your client. Enter the boat's details and the app finds the motor, the battery bank and the peripherals, works out range and cost, and produces a complete PDF quotation. PROPULSION DESIGN • Match an electric motor to the existing combustion engine by torque equivalence • Size from displacement and speed — or the other way round, from requirements • Hull material on every screen: composite, aluminium, steel, plywood, solid wood, carbon • Hybrid conversion: keep the combustion engine and add a motor with a battery — Transfluid mechanical subsystem, belt-drive solution, SAE check, gearbox reduction PROPELLER AND RESISTANCE • Propeller selection and design from open-water series, with nozzles and cavitation check • Performance curve against rpm, and bollard pull • Hull resistance with methods validated per category, plus appendages and air drag ENERGY, RANGE, SAIL • Route on a nautical chart with charging stops and a battery balance • Solar, a range-extending generator and hotel loads • Declare the rig and the sail counts in the trip energy; regeneration under sail returns energy to the battery DEAS — BOAT ENERGY EFFICIENCY INDEX An A–G energy rating from the CO₂ index, for electric and combustion boats alike, with a PDF certificate and QR code. Free for everyone. ONE POWER CHAIN Resistance, shaft power, propeller and energy come out of one shared chain: the same boat gives the same answer in every module, whichever you enter from. TRADITIONAL WOODEN HULLS Fifteen types, lines from 51 measured drawings and real hulls; indicative ones are marked. Give length and timber; you get dimensions, member-by-member weight and a timber supply list with two figures: what goes into the hull and what to order. Midship section on screen and in the report, open or decked, which rule applies, and the source of every dimension in the annex. DOCUMENTATION FOR TECHNICAL REVIEW The quotation can carry a technical annex with the methods used and their stated limits — for a classification society, a naval architect or a surveyor. ELECTRICAL STUDY • Load balance underway and at anchor • Single-line diagram on A3 — or across A4 sheets, at full size, with continuation references • Circuit schedule with cable sections, voltage drop and protection — the three documents a classification society asks for STANDARDS BY MODULE • Resistance & Propeller: BV NR500 · ISO 8665-2 (definitions) • Geometry & Stability: ISO 12217-1 · ISO 12217-2 · ISO 8666 (definitions) • Structure & Weight: ISO 12215-5 · BV NR546 · BV NR500 • Reverse sizing: ISO 12215-5 · BV NR546 · BV NR500 · ISO 23625 · ISO 8665 / ISO 8666 (definitions) • Sailing: ISO 12215-9 · ISO 12215-5 (definitions) • Hybrid Conversion: ISO 16315:2026 (definitions) • Traditional hulls — Materials & construction: ISO 12215-5 • Workboats: ISO 12215-5 • Energy & Range Calculation: ISO 8666 · ISO 23625 (definitions) • Electrical study: ISO 13297 · IEC 60092-507 · ISO 16315:2026 · ISO 23625 · BV NR500 • DEAS: ISO/TS 25128 (reference) FREE AND MODULES • Free: the WHOLE calculation — motor, battery, range, savings, DEAS grade • Ten study modules: Resistance & Propeller · Geometry & Stability · Structure & Weight · Reverse sizing · Sailing · Hybrid Conversion · Traditional hulls — Materials & construction · Workboats · Energy & Range Calculation · Electrical study • Each module comes as a one-off purchase or an annual rental — the same rights. The rental is an annual subscription that renews automatically and is cancelled in your store account settings; when it ends, the module locks. • With at least one module, quotation documents and method updates are included.
