RYA Essential Navigation and Seamanship (awarded by the RYA)

The RYA Essential Navigation and Seamanship course is a friendly first step into navigation and safety awareness for anyone heading out on a sailing boat or motorboat. It gives you enough understanding of charts, tides, buoyage and the rules of the road to stay out of trouble close to shore, without the depth (or the exam pressure) of a full skipper theory course.

The RYA runs it as about 16 hours in a classroom or roughly 8–10 hours online. There are no entry requirements and no minimum age.

Who it suits

• New boat owners, under sail or power, who want the basics before going out on their own
• Crew who'd like to understand what the skipper is doing at the chart table
• Returning boaters who want a structured refresher
• Anyone not yet ready to commit to the longer Day Skipper Theory course

What you'll actually do

In the classroom you work through a course handbook and exercises using a real chart, a plotter and dividers, so you get hands-on practice measuring distances, reading symbols and laying off simple courses. Online, the same ground is covered through interactive exercises at your own pace. Topics include charts and publications, safety, engine checks, buoyage, tidal awareness, visual and electronic navigation, pilotage, rules of the road, anchoring, weather forecasts and passage planning. The emphasis is on practical awareness rather than precise calculation.

Key ideas explained

• Reading a chart — depths are shown relative to chart datum, a low reference level the tide rarely falls below, so there is usually at least the charted depth. Distance is measured on the latitude scale at the side of the chart: one minute of latitude equals one nautical mile.
• Buoyage — Australia uses the IALA Region A system, as the UK does. Heading into harbour from seaward, red port-hand marks stay on your left and green starboard-hand marks on your right. Cardinal marks show which side the safe water lies: pass north of a north cardinal.
• Tidal awareness — the sea rises and falls, and it flows as tidal streams. Spring tides (around new and full moon) have the biggest range and strongest streams; neaps the smallest. Tides vary hugely around Australia, so always check local predictions.
• Pilotage — navigating by eye close to land, using transits (two fixed objects lined up), clearing lines and a plan prepared before you leave.
• Rules of the road — keep a proper lookout, go at a safe speed, take early and obvious action. Two power-driven vessels meeting head-on both turn to starboard, and an overtaking vessel keeps clear.
• Passage planning — check the forecast, tides, hazards and places to shelter, and tell someone ashore your plan.

Where it fits

Getting ready

• No study is needed beforehand, but being comfortable adding and subtracting times helps with tides
• If you boat locally, bring a chart of your home waters to relate the ideas to
• Ask the school whether the course is classroom or online, and which charts the exercises use
• Online learners: set aside a few sessions rather than one long sitting

Good to know in Australia

• This course is not a boat licence. Recreational licences are issued by each state and territory, so check your state's maritime authority.
• To use a marine VHF radio you need a qualification such as the SROCP.
