Everything in Marine Simulator Training One subscription — every simulator, and it keeps growing
Built by sailors for sailors: the rules of the road, the radio, the harbour, the sails and the chart — trained in real wind on the real Baltic Sea, at your own pace, as often as you like. Every part below is included.

Docking & berthing — Harbour Ready
35 step-by-step lessons in 8 modules: coming alongside, springs, marina boxes, piles, stern-to on a lazy line and on your own anchor, a catamaran, a tanker with tugs — and a pre-charter harbour run. 107 real harbours, 22 vessels, real wind; every lesson explained and scored.
Sails trim simulator
What the traveller, the sheets and the cars really do — in three levels. 3-D sails with every telltale, the airflow round them (faster air, lower pressure, turbulence when a sail stalls), heel and helm balance, waves and gusts, the spinnaker gybe with lazy guys.
The Baltic Lap — an online rally-regatta
One race round the Baltic, all the time, in the real wind — free to join. With your subscription the skipper's extras open: laylines, your own route with a TRACK autopilot, wind-angle steering, auto sails and the Code Zero.
COLREG · AIS bridge simulator
54 collision-avoidance scenarios: AIS targets, lights, day shapes and sound signals, crossing, overtaking, restricted visibility, traffic separation — every decision checked against the rule.
VHF SRC radio simulator
15 radio drills on a working set with a DSC keypad: Mayday, DSC distress alert, Mayday Relay, Pan-Pan, Sécurité and routine calls.
Online sailing simulator
Trim, tack, gybe, reef and fly a spinnaker in the real forecast wind: cruising yachts, dinghies, a catamaran and an AC75 foiler.
Chart plotter (ECDIS) simulator
Plan a passage on a chart with real depths, then test it for your own vessel — length, beam, height and draft against the shallows, the narrows, the bridges and every turn — and sail it.
Radar, AIS and the chart on every bridge
A working radar and AIS on board, the chart with your route and waypoints and an autopilot that follows it — the instruments a skipper really uses.
Man overboard and emergency drills
The MOB manoeuvre under sail and power, and the drills a skipper hopes never to need — practised where a mistake costs nothing.
The whole Baltic, in real weather
Real coasts, harbours and seamarks; the wind and the waves from the forecast, hour by hour. Start from any Baltic harbour — on a phone, a tablet or a computer.

Why a simulator Reading the COLREGs ≠ knowing what to do on the graveyard watch in fog.
Books and videos make you recognise the rules. Simulators make you act on them — under time pressure, with the right priorities, until the correct decision is muscle memory. Practise the same situations over and over, fail safely, and walk onto the bridge with answers already loaded.
Decisions, not facts
Each scenario asks: what action do you take, what signal do you give, who gives way? Wrong answer → instant feedback citing the exact rule.
Repeat until automatic
Re-run any scenario as many times as you like. Track your progress per scenario. The goal isn't to "pass" — it's for the right call to feel obvious.
Built for exam prep
Every scenario maps to a COLREG rule or a VHF SRC procedure that examiners actually test. The titles cite the rule directly so you build a map of the syllabus while you train.
What you'll be able to do Concrete skills you'll walk away with
Cross a TSS the right way— at right angles, knowing when you're a "vessel using the lane" and when you're "crossing".
Read any vessel's lights at night— rotate the target ship 360° and see exactly which lights show from each angle. No more confusing a tug from a fishing vessel.
Train right-of-way until it's reflex— power vs sailing, fishing, restricted, constrained-by-draught. Drilled in dozens of variations until you don't need to think.
Handle multiple ships at once— the realistic case where two or three targets converge. Practise the priority of action that single-target scenarios never teach.
See COLREG visually— go through the rules with the actual ship in front of you, not a paragraph in a book. The rule reads itself when you watch it happen.
Practise DSC for real— send distress, urgency, safety and routine DSC calls on a working keypad. Build the muscle memory before the real radio is in your hand.
Press the red button safely— the one place in the world you can fire a Mayday and a DSC distress alert without scrambling the coastguard. Drill it until it's second nature.
COLREG · AIS Bridge Simulator 54 collision-avoidance scenarios across 7 modules
A web-based bridge: AIS targets, radar, lights, sound, ship-handling response. Pick a scenario, assess the encounter, decide on action, get feedback against the actual COLREG. From the basics of CPA/TCPA to multi-target night encounters.
Fundamentals 6 scenarios
Build the underlying habits — risk assessment, lookout, CPA/TCPA reading — that every other scenario builds on.
Includes
- Familiarisation – free roam mode Free demo
- CPA/TCPA recognition
- Safe speed

- Crossing — give-way
- Crossing — stand-on
- Overtaking

Questions Frequently asked
Will I get a certificate from this membership?
No — this membership unlocks the simulators so you can train. The VHF SRC and Skipper Refresher certificates are issued only with the corresponding one-time course purchase. The good news: any exam you pass and any simulator you complete while subscribed counts retroactively if you later buy the course — no progress wasted.
Do the simulators really teach COLREG, or are they quizzes?
Decision-based scenarios. You see the encounter — bearing, range, lights, AIS data, sound — choose the correct action under the relevant rule, and get feedback citing the rule. The COLREG simulator covers Rules 2, 5–10, 12–19, 23–30, 34 and 35; the VHF simulator covers the GMDSS / SRC voice and DSC procedures.
Maritime education is moving online fast, and a browser simulator lets you rehearse the same decisions as often as you like, between seasons and between watches, at no risk.
And this kind of training fits everyone who operates on the water — from yacht skippers to officers on big ships. The rules are the same for all of us, and the sea is shared.

What if I don't like it?
14-day money-back guarantee — no questions asked.
If the simulator isn't for you, send us a message via the contact form within 14 days of purchase and we'll refund you in full.
Does this auto-renew?
No — it's a one-time payment for a fixed period. Your card is never charged again automatically. When your access runs out, buy another month or year whenever you want to continue. No phone calls, no retention questions.
Monthly or annual?
Monthly (€19.99/month) is ideal if you have an exam coming up or want to try before committing. Annual (€79/year) works out to €6.58/month — a 67% saving. Both are one-time payments with no auto-renewal.
What devices does it work on?
Anywhere with a modern browser — desktop, laptop, tablet, phone. The bridge simulator is best on a screen wide enough to see lights and AIS targets clearly, so we recommend tablet-or-larger for the COLREG scenarios. The VHF simulator works comfortably on a phone.
Is content updated?
Yes — while your Simulator Training plan is active you get every addition automatically, no extra cost.
