RYA Day Skipper Theory study plan

Explain how latitude and longitude, the compass rose, and chart scale work on a paper chart, and state the scale of two different charts in words and figures.

Convert between true, magnetic, and compass bearings using variation and deviation, and calculate the resulting error for at least ten worked examples.

Plot and read a three-bearing fix and a running fix on a training chart, labelling times and log readings.

Measure distance and speed using the latitude scale and the dividers, showing the arithmetic for each step.

Use the tidal curve (standard port) to find height of tide for a given time, and find the time for a required height, for six different tidal days.

Apply the rule of twelfths to estimate tidal height change across a single tide and compare it with the curve result.

Calculate secondary port corrections for time and height using the tidal differences table.

Determine chart datum depths, drying heights, and the actual depth of water at a stated time and place.

Compute a safe course to steer to counteract a known tidal stream over a single leg, using a vector triangle drawn to scale.

Calculate estimated position (EP) from course, speed, and tidal set and drift, and mark it with the correct symbol.

Work out the course to steer and speed made good for a passage with a cross-tide, checking the answer by plotting.

Explain the difference between set and drift, and between an EP and a fix, in your own words.

Interpret chart symbols for buoys, lights, fog signals, wrecks, and restricted areas, and identify each from a list without the key.

Read light characteristics (flashing, occulting, isophase, group flashing) and match them to charted lights.

Plan a short coastal passage on a training chart, marking waypoints, hazards, and safe water.

Calculate ETA for each leg using distance, planned speed, and expected tidal assistance.

Draft a passage plan for a multi-leg coastal route, listing departure time, tidal gates, and contingency anchorages.

Apply the buoyage system (IALA Region A) to identify safe entry and exit channels in a harbour approach.

Describe pilotage techniques: leading lines, clearing bearings, transits, and depth contours, and apply two of them to a harbour entry.

Explain how to use GPS and electronic charts as a backup to, not a replacement for, paper chartwork.

Apply the collision regulations (lights, shapes, sound signals, and give-way rules) to at least ten written scenarios and state the correct action.

Identify vessel types by their night lights and day shapes, and state each vessel's obligations.

Explain the hierarchy of responsibility, safe speed, and risk of collision, and apply them to a crossing situation.

Describe the actions to take in restricted visibility and the signals that accompany them.

List and explain the safety equipment carried on a day-skipper yacht, including lifejackets, flares, liferafts, and fire extinguishers, and their stowage.

Describe man-overboard procedure, including the actions of helm and crew, and the recovery sequence.

Explain the use and limitations of VHF radio, including DSC, channel selection, and MAYDAY, PAN PAN, and SECURITE calls.

Outline hypothermia prevention, first aid priorities, and the procedure for requesting assistance.

Complete two full-length mock papers under timed conditions, covering all four domains.

Review every incorrect answer, identify the underlying method error, and rework each problem correctly.

Revisit the weakest two domains with targeted practice and confirm improvement on a second attempt.

Summarise the key formulas and rules on a single revision sheet for final review.
