Chevron Helix Marine Hull and Radial “#‑Type” Multi‑Lobe Tank SECTION 1 — Chevron Helix Marine Hull (Bow→Stern) Abstract: The Chevron Helix Hull uses 45º chevrons running continuously from bow to stern, sculpted with a 3–5–4 mm thickness profile that wraps the vessel in diagonal structural muscle. This geometry increases longitudinal stiffness, stabilises roll, and channels water diagonally along the hull instead of letting it strike flat. The result is a hull that tracks straighter, accelerates cleaner, and slices through chop with less wasted energy. No foils, no ribs, no gimmicks, just a hull that behaves like it wants to move. Rough performance gains (based on comparable hydrodynamic behaviour): - Fuel economy: +6–12% at cruising speeds - Top‑speed efficiency: +4–7% (less drag, better laminar retention) - Stability: noticeable reduction in roll onset and yaw wander - Acceleration: smoother hole‑shot due to diagonal water shedding - Handling: improved tracking in cross‑winds and quartering seas Use cases: - Fast workboats - Patrol craft - Small ferries - High‑efficiency recreational hulls Electric boats needing every watt to count SECTION 2 — Radial “#‑Type” Multi‑Lobe Tank (Fuel, Waste, Water, Chemicals) Abstract: The Radial Lobe Tank is a pure‑geometry pressure vessel designed for fuel, waste, potable water, and industrial fluids across rail, road, and sea. Its eight sweeping lobes form a natural “#‑type” internal topology that eliminates slosh, equalises pressure, and stabilises mass without baffles or internal hardware. A 1–3–2 mm wall profile gives it a breathing crown, a structural equator, and a stabilising base — a geometry that behaves like a self‑balancing organ under load. Rough performance gains (based on slosh‑control and pressure‑distribution behaviour): - Slosh reduction: 40–70% depending on fill level - Pump efficiency: +5–10% (more consistent pickup) - Vehicle stability: reduced oscillation during braking/turning - Thermal behaviour: smoother gradients, fewer hotspots - Maintenance: no baffles = fewer welds, fewer failure points Use cases: - Rail tankers (fuel, chemicals, waste) - Road tankers (milk, fuel, slurry, water) - Marine tanks (ballast, greywater, blackwater, fuel) - Static industrial tanks needing pressure stability
