SL MarMaster Mariner · Quantitative Research

Maritime expertise, working software.

Master Mariner (MSc, LLM), 27 years at sea and 11 in command, with a quantitative background in ship performance. I build weather routing, cargo simulation, ship modelling and on-board AI, calibrated to real vessels, trades and operating data. All deliverables and IP transfer to the client.

What I build

Four domains, one operational thread

Every tool starts from a real vessel and its data, and hands back something you own.

Maritime routing

Weather-routing and ship-performance studies on your vessel's real data: seasonal routing studies and ERA5 voyage replays, powered by WindMar.

Explore

Cargo simulation

Vessel-specific simulators: LCS-Mar for liquid cargo and LGSMar for gas. Your own piping, tanks and cargo machinery, with realistic physics your crew can train on.

Explore

Ship modelling

Performance models (Holtrop-Mennen, THETIS-MRV corrected), manoeuvring and berthing, 3D visualisation and CFD: the physics behind the routing.

Explore

Local AI

On-premises AI over your own manuals, procedures and records. Local inference with page-level citations, no cloud, operational at sea.

Explore

Grounded in your vessel's real data.
