MetaCAD is the first maritime CAD that runs entirely in your browser — 14 modules, 113+ calculators, all backed by a Rust core compiled to WebAssembly with WebGPU acceleration for Monte-Carlo dynamics.
We replace $15K–$30K Windows-only seats (NAPA, GHS, Cargomax, Paramarine) with a free tier that any class society inspector, surveyor, or chief engineer can open in 30 seconds.

| Emissions compliance | CII (MEPC.336/354/400), EU ETS Phase 2, FuelEU Maritime, bulk fleet |
| Bunker reconciliation | MFM vs BDN per MPA SS 660 + TR 48, Letter of Protest generator, eBDN audit trail |
| Scantlings | ISO 12215-5 hull plating + framing |
| Operations | Draft Survey (full cycle, 13 port pages), PSC compliance, hull design studio |
| AI Copilot | 35 specialised maritime agents — BYOK on your OpenAI / Anthropic / OpenRouter key |
- FuelEU Maritime first surrender cycle: January 2026 — fleets are mid-audit right now.
- MPA Singapore SS 660 mandatory for all bunker deliveries from Q1 2026.
- EU ETS Phase 2 — 75% allowances 2026 → 100% 2027.
- WebGPU + Rust → WASM crossed mainstream-browser maturity in 2024. The window to be the default browser-native CAD opens once.
 Live Loadicator — synthetic Kongsberg-style DAU bus, full IMO IS Code stability + SF/BM longitudinal strength, 3D tank-fill, recalc 1 ms |
 IMO CII — MARPOL Annex VI Reg 28 + MEPC.400(83). Live attained CII, A–E rating, FuelEU CO₂eq, step-by-step math (Anti-Black-Box) |
 Singapore MFM Reconciliation — MPA SS 660 / TR 48 / eBDN 2025. 7 documented short-delivery tactics, $90 K install cost saved per surveyor |

benchmarks |
Reproducible validation cases — ONRT capsize MC, KVLCC2 GZ-curve, CII bulk fleet wall-clock. Open-core: fixtures + expected outputs only; runtime is in the closed-source WASM core. |
More repos open as Phase 0 validation milestones land.
