An online sailing course for beginners

Marinero is an online sailing course built for complete beginners. It teaches the theory every new sailor needs — the parts of the boat, the points of sail, the knots, the right-of-way rules, weather and safety — in short, illustrated cards you learn at your own pace, on your phone or laptop. No jargon dropped on you, no four-hour videos, no subscription. Start free and only pay once if you want the whole course.

Can you actually learn to sail online?

Half of it, honestly — the half that matters before you ever cast off. Sailing is part knowledge and part feel. The feel — balancing the helm, reading a gust, coming alongside — only comes from time on the water, and no app replaces that. But the knowledge is exactly what beginners find overwhelming on day one: a hundred new words, invisible wind angles, ropes that all look the same. Learn that ashore, at your own pace, and you step aboard already understanding what the skipper is talking about instead of nodding along. That is what an online course does well, and it is what Marinero focuses on.

What a beginner needs to learn first

The boat
Hull, keel, rudder, mast, boom, the sails and the hardware on deck — so nothing on board is a mystery.
Wind & points of sail
Why a boat can't sail straight at the wind, and the angles from close-hauled to a run.
Knots
The six knots that cover almost everything: bowline, cleat hitch, clove hitch, reef, figure-eight, round turn.
Rules of the road
Port and starboard, who gives way, and how to not have an argument at sea.
Navigation basics
Buoys, charts and headings — enough to know where you are and where you're going.
Weather & safety
Reading a forecast, reefing early, lifejackets and what to do when it pipes up.

How Marinero teaches it

Every topic is broken into small cards, and each card runs through the same three-step loop so it actually sticks:

Learn → Practise → Master

  • Learn — a clear, illustrated explanation of one idea.
  • Practise — a quick question to check you've got it.
  • Master — recall it later, from memory, to lock it in.

Built for beginners

  • Plain English, no assumed knowledge.
  • Interactive diagrams, not walls of text.
  • Two-minute sessions — learn on the bus.
  • Climb from Deckhand to Capitán as you go.

The ten modules

1 · Parts of the boat
Everything from bow to stern, named and explained.
2 · Wind & points of sail
The single idea the whole sport turns on.
3 · Sail trim
Telltales, sheeting in and out, making the boat go.
4 · Knots & lines
The six essential knots and when to use each.
5 · Rules of the road
Right of way, lights and shapes, avoiding collisions.
6 · Manoeuvres
Tacking, gybing, mooring and coming alongside.
7 · Navigation
Charts, buoyage, headings and fixes.
8 · Weather
Forecasts, wind, and knowing when to stay in.
9 · Safety & systems
Lifejackets, engine checks, man overboard.
10 · Seamanship
The habits that make a good crew member.

An online course, not a replacement for the water

To be straight with you: Marinero is not an RYA or ASA certification, and it does not put you at the helm. What it does is make the on-water part far less bewildering — and far cheaper to make the most of. A day of real sailing tuition is expensive; spend it learning to steer, not learning what "leeward" means. Beginners who arrive already knowing the theory get more out of every hour afloat, and often decide much faster whether the sport is for them.

Common questions

Can you learn to sail online?

You can learn the theory — boat parts, points of sail, knots, right-of-way rules, navigation and safety — completely online, and that is the part beginners find hardest. The physical feel of steering and trimming only comes from time on the water, so the best approach is to learn the knowledge online first and then spend your on-water time practising the skills.

Is Marinero good for complete beginners?

Yes — it is built specifically for people who have never sailed. Everything is in plain English with no assumed knowledge, taught one small idea at a time with interactive diagrams rather than jargon.

How long does it take?

As long as you like — it is self-paced. Sessions are about two minutes each, so most people work through it in short bursts over a few weeks. The free tools take only a minute to try.

Does it replace an RYA or ASA course?

No. Marinero is not a certification and does not put you at the helm. It teaches the theory so that a real-world course, charter or day out is far less overwhelming — and so you get more from every hour on the water.

How much does it cost?

You can start for free. The full course — all ten modules and 330+ cards — is a single one-time payment of €34.99, the Capitán tier. There is no subscription and no ads.

What do I need to start?

Just a phone, tablet or laptop and a web browser. Nothing to install, and no boat required.
