For Masters & Navigation Officers

Decision Support That Respects Seamanship

The AI shows its work. You make the call.

16% better predictive power on wave height — across the validated voyage set.
The brief

Transparent decision support: natural-language explanations, full raw weather at every waypoint, and a complete audit trail that defends every call.

VesselFront was built by people who understand that the Master’s authority is absolute, legally and practically. Our system doesn’t replace judgment. It provides transparent decision support: natural-language explanations for every recommendation, full raw weather data at every waypoint, and a complete audit trail that protects you when decisions are questioned after the fact.

What you get

Three decisions built around your role

The features masters & navigation officers actually use on a Wednesday at 14:00.

01

Natural-language rationale

Why the optimizer chose this heading, this speed, this depth — in plain English, ready to log.

02

Constraint-aware modes

Switch between fuel efficiency, ETA, and balanced routing modes that respect draft, ECA zones, and master’s discretion.

03

Charter-party defensible

Recommendations carry the citation chain back to weather sources, vessel particulars, and prior performance data.

Proven in the field

Voyages that vindicate the masters & nav officers brief

Real commercial passages — not synthetic benchmarks. Each one is reproducible from raw inputs.

Eastbound tanker voyage from Tubarão to Port Louis, 20 days, 5,514 nm – across the South Atlantic, round the Cape of Good Hope, across the southern Indian Ocean. September 2023. The lane runs entirely through the Southern Ocean's high-sea-state corridor; the historical replay spent 100% of the voyage at Sea State 4+ and 13.7% at Sea State 6+ (≥4 m), with a 6.09 m peak just south-west of the Cape. The optimised track cut Sea State 6+ exposure to 1.3%, a 10% reduction, and Sea State 5+ exposure from 62.4% to 40.9%. Peak wave encounter dropped from 6.09 m to 4.29 m, and the peak itself relocated: from the Cape's stormiest zone to a milder corridor south-east of Madagascar. Mean SOG 11.6 kn. The result was a 14.34% FOC saving (84 MT), outside any ECA, so a clean routing-and-weather management saving rather than a fuel-grade effect.

Winter Baltic voyage from Porvoo (Sköldvik) to the Skaw STS area off Skagen – three days, 819 nm, westbound through the Gulf of Finland, across the Baltic, and out through the Danish Straits. The entire route runs inside the Baltic and North Sea SECAs, so the 4.9 MT FOC saving is realised entirely on ECA-grade fuel. The optimised track held at a 1.03 m mean significant wave height with a 2.68 m peak in the southern Baltic, and reduced Sea State 5+ exposure from 12.0% of the historical track to 1.5% – about 90 minutes of brief Sea State 5+ conditions versus roughly 9 hours on the historical replay. Mean SOG 11.31 kn.

India-to-Brazil voyage from Sikka to Niterói, routing south through the Indian Ocean, around the Cape of Good Hope, and across the South Atlantic – 30 days, 7,922 nm. The operational risk on this lane is the Cape rounding, where the route hit its southernmost point at 35.9°S in the Roaring Forties. The optimised track cut Sea State 6+ exposure (≥4.0 m) nearly in half – from 6.4% of the historical track to 3.6% – and reduced Sea State 5+ exposure from 36.0% to 26.0%. Route-averaged significant wave height was 2.17 m. The vessel operated on VLSFO throughout with no ECA transits, so the 13.31% FOC reduction (89 MT saved) is a pure routing-and-speed optimisation result, not a fuel-grade effect.
