Theory and practical skills to skipper a yacht safely in familiar waters during daylight hours.
The RYA Day Skipper course covers navigation, meteorology, and boat handling — everything you need to take charge of a yacht on short coastal passages in familiar waters during daylight.
Aspiring skippers who want to charter or skipper their own yacht in coastal waters. The Day Skipper Practical certificate is the minimum most charter companies will accept for bareboat charter in the Mediterranean.
Tidal heights and tidal streams — the calculations that catch out more candidates than any other topic in Day Skipper theory.
Tides are the rise and fall of sea level caused by the gravitational pull of the Moon (and to a lesser extent the Sun) on the Earth's water. Most UK and European coasts experience two highs and two lows per day — roughly every 6 hours and 12 minutes between high and low water.
The five terms to know cold
Springs happen around full and new moons (when Sun and Moon pull together). Neaps happen around the first and last quarter moons (when they pull at right angles). The cycle is roughly 14 days. Springs give big ranges and fast streams; neaps give small ranges and slow streams.
Synoptic charts, fronts, sea breezes, and the forecasts you actually use at sea. Enough to plan a passage and avoid the wrong day.
A synoptic chart is the Met Office's snapshot of the surface pressure pattern, fronts, and weather systems. The lines on it are isobars — lines of equal atmospheric pressure measured in millibars (mb). Pressure systems are labelled H (high pressure) and L (low pressure).
What isobars tell you
Fronts are boundaries between air masses of different temperatures. Warm fronts (red lines with semicircles) bring gradual cloud build-up, rain, and warmer air. Cold fronts (blue lines with triangles) bring more sudden, sharper rain showers and cooler air. Occluded fronts (purple, alternating symbols) are where a cold front has caught up with a warm front.
The International Regulations for Preventing Collisions at Sea — the rules of the road for ships. The Day Skipper exam focuses on Rules 5–19 plus lights and shapes.
COLREGS has 38 rules and seven annexes. For Day Skipper you need to know five of them cold, and have a working knowledge of the rest.
The five for Day Skipper
The IMO 4 stages of passage planning, applied to a short coastal passage. Where most of the practical thinking comes together.
The International Maritime Organization specifies that every passage should follow four stages: Appraisal, Planning, Execution, Monitoring. The exam loves to ask you to identify which stage covers which activity.
The four stages
Man overboard procedures, distress signals, flares, and the safety equipment every yacht must carry.
Man overboard (MOB) is the single most rehearsed scenario in sailing because the consequences of botching it are fatal and the actions are time-critical. The Day Skipper exam tests three recovery methods.
