Sailing Logbook Examples: 4 Practical Entries

Not sure what to write in your sailing logbook? Seeing a few real-world-style examples makes it much easier to get started.

A useful logbook doesn’t need to read like a novel. It should record what happened, when it happened, the conditions you encountered, and any information that could help you understand the trip later.

In this guide, you’ll find four illustrative sailing logbook examples: a day sail, a longer passage, a change in weather, and an onboard incident. Each shows how to turn a few observations into a clear, useful record.

The examples are fictional and intended to demonstrate record-keeping, not to provide navigational advice.

1. Day sailing logbook example

For a short coastal sail, focus on the main stages of the trip: departure, conditions underway, significant events, and arrival.

You don’t need to record every small adjustment. Capture the information that helps reconstruct the outing afterward.

Example entry

Time	Logbook entry
09:00	Departed Port A with three people on board. Weather partly cloudy, westerly wind approximately 8–12 kn (15–22 km/h / 9–14 mph), slight sea.
09:25	Cleared the harbour entrance. Main sail and jib set. Vessel making approximately 4.5 kn (8.3 km/h / 5.2 mph) over ground.
10:30	Continued on a southwesterly course. Wind increased slightly. Crew comfortable; no issues reported.
12:00	Anchored in a sheltered bay in 5 m (16.4 ft) depth for lunch. Position recorded on the chartplotter.
13:15	Weighed anchor and resumed sailing. Wind approximately 10–14 kn (18.5–26 km/h / 11.5–16 mph).
15:40	Returned to Port A and secured the boat. Distance covered 18 NM (33.3 km / 20.7 mi). No incidents or equipment issues observed.

All times, locations, and measurements are illustrative.

What makes this entry useful?

• A clear timeline: You can reconstruct the main stages of the outing.
• Conditions: Wind and sea state provide context for the decisions made.
• Navigation context: Course, speed, and position help describe the route.
• A closing entry: The arrival time marks the end of the trip.

For a short outing, this level of detail may be sufficient for a personal record. The amount and frequency of recording should increase when conditions, the voyage, or applicable rules call for it.

2. Longer sailing passage logbook example

A longer passage usually benefits from more structured entries. Recording information at regular intervals makes it easier to identify changes in conditions and understand how the passage progressed.

The appropriate interval depends on the vessel, crew, conditions, and any applicable requirements. A personal logbook should not replace the watchkeeping or official records required for a particular voyage.

Example entry

Time	Position	Conditions and observations
08:00	Position recorded	Departed for a planned coastal passage. Wind from the northwest at approximately 10 kn (18.5 km/h / 11.5 mph). Main sail and jib set.
10:00	Position recorded	Steady progress at approximately 5 kn (9.3 km/h / 5.8 mph) over ground. Distance run: 10 NM (18.5 km / 11.5 mi). Slight sea. Visibility good.
12:00	Position recorded	Wind increased to approximately 15 kn (27.8 km/h / 17.3 mph). Crew reviewed the sail plan and prepared for changing conditions.
14:00	Position recorded	Reduced sail area as conditions strengthened. Vessel remained under control; crew briefed on the next stage.
16:00	Position recorded	Wind eased to approximately 12 kn (22.2 km/h / 13.8 mph). Route and estimated arrival reviewed.
18:30	Arrival position recorded	Arrived at destination and secured the vessel. Total distance: 52 NM (96.3 km / 59.8 mi). Passage completed without incident.

For a real passage, replace “position recorded” with the actual latitude and longitude or the position format used in your logbook. Include the relevant time reference, such as UTC or local time, and use it consistently.

What should you add for a longer passage?

Depending on the voyage, useful details may include:

• Position, course, speed, and distance made good in NM (km / mi).
• Wind direction and force in kn (km/h / mph), visibility, and sea conditions.
• Sail configuration and significant changes to propulsion.
• Watch changes and relevant crew observations.
• Navigation decisions, deviations from the plan, and reasons for them.
• Equipment problems, communications, and other significant events.

The goal is not to fill every line. It’s to create a reliable record of the passage and the circumstances in which it took place.

3. Sailing logbook example for changing weather

Weather changes are worth recording because they explain why you altered your sail plan, route, or schedule.

Rather than writing only “wind increased,” describe what you observed, what you did, and what happened afterward.

Example entry

14:20 — Conditions changing

Wind increased from approximately 10 kn (18.5 km/h / 11.5 mph) to 17–20 kn (31.5–37 km/h / 19.5–23 mph), with short gusts up to 25 kn (46.3 km/h / 28.8 mph). Sea becoming more developed. Reduced sail area and checked that the crew were prepared for the next manoeuvre. Reviewed the route and the available sheltered options.

15:00 — Conditions reassessed

Wind remained fresh, with occasional stronger gusts. Vessel handling remained satisfactory. Continued on the revised plan while monitoring the conditions.

15:45 — Decision recorded

Decided to head for the planned sheltered destination rather than continue the original route. The decision was based on the changing conditions and the preference to complete the passage with a greater margin of safety.

Why this format works

A good entry distinguishes between three things:

1. Observation: What were the actual conditions?
2. Action: What did the crew change or check?
3. Reasoning: Why was the decision made?

That distinction can be valuable when reviewing a passage later. It also helps you learn from experience rather than simply remembering that the weather was difficult.

Avoid recording estimates as exact measurements. If you didn’t measure the wind, describe it as an estimate or observation rather than implying a precise instrument reading.

4. Sailing logbook example for an onboard incident

A logbook can also document equipment problems, unexpected events, and other incidents.

For these entries, prioritize a factual timeline. Record what was observed, what actions were taken, and the outcome. Avoid speculation, blame, or assumptions about the cause.

Example entry

11:42 — Equipment issue observed

The engine alarm sounded while the engine was running. The alarm type and instrument readings were checked where safe to do so. The crew were informed.

11:44 — Response

Followed the engine manufacturer’s guidance and the vessel’s procedures. The engine was stopped when safe to do so. The crew assessed the situation and considered the available options.

11:55 — Follow-up

Recorded the observed symptoms and the actions taken. The issue remained unresolved, so the crew reassessed the plan and arranged appropriate assistance.

12:30 — Outcome

Recorded the subsequent actions, communications, and outcome, including any assistance received.

This is an illustrative record-keeping example, not an engine troubleshooting procedure. The appropriate response depends on the alarm, vessel, conditions, and manufacturer’s instructions.

Information to record after an incident

Depending on the event, include:

• Date, time, and position.
• Conditions at the time (wind in kn (km/h / mph), sea state, visibility).
• What was directly observed.
• People involved or affected, where relevant.
• Actions taken and by whom.
• Communications and assistance requested or received.
• Outcome and any follow-up required.
• Relevant photographs or supporting documents, where appropriate and safe to collect.

Keep the language neutral and precise. For example, “The alarm sounded and the engine temperature indication increased” is more useful than “The engine suddenly broke for no reason.”

A personal logbook may support your recollection, but it does not necessarily satisfy formal incident-reporting obligations. Those obligations depend on the circumstances and applicable rules.

5. A simple sailing logbook entry template

You can use the following structure as a starting point and adapt it to your vessel and type of sailing.

Basic trip record

Field	What to record
Date	Date of the trip
Time	Time of the entry, with a consistent time reference
Vessel	Boat name or identifier
Crew	People on board, as relevant
Position	Latitude and longitude when useful
Course and speed	Course, speed in kn (km/h / mph), and distance in NM (km / mi) when available
Weather	Wind in kn (km/h / mph), visibility, clouds, and significant changes
Sea conditions	Wave conditions, wave height in m (ft), swell, and current when relevant
Activity	Departure, manoeuvre, anchoring, sail change, arrival, etc.
Notes	Observations, decisions, equipment issues, or memorable moments
Photos	Optional visual context for the trip

Not every entry needs every field. A short note about anchoring may not require a full weather report, while a passage entry may need considerably more detail.

For more guidance on the fields themselves, see What to Write in a Sailing Logbook.

Copy-and-use example

You can also use this compact format for each entry:

Date and time: Position: Activity or event: Weather and sea conditions: Course, speed, or distance: Action or decision: Outcome and additional notes:

Keep the fields that are relevant to your sailing and omit those that add no value. For a more complete starting point, see the Sailing Logbook Template.

6. What makes a good sailing logbook entry?

Across all these examples, a few principles make the difference between a logbook that is useful and one that becomes difficult to interpret.

Be factual

Separate observations from assumptions. If you estimate a wind speed or infer a cause, make that clear.

Be consistent

Use the same units, time convention, and general structure whenever practical. Consistency makes different entries easier to compare.

Record significant changes

A change in weather, route, sail configuration, propulsion, or crew circumstances may be more useful than a long list of routine observations.

Write entries while the details are fresh

Short entries made at sensible intervals are generally more reliable than trying to reconstruct an entire trip from memory afterward.

Keep context

A number alone may not tell the whole story. Recording why you changed course or reduced sail can help explain the decisions behind the trip.

7. Paper or digital sailing logbook?

Both formats can work. The important thing is that the record is clear, consistent, and suitable for its intended purpose.

A paper logbook offers a simple physical record and can be useful when electronic devices are unavailable. A digital logbook can make it easier to organize entries, review past trips, and connect notes or photographs with a voyage.

With Skipper, you can keep a digital record of your sailing trips, including GPS tracks, routes, distance, duration, and speed, while adding details such as weather, crew, locations, notes, and photos. You can then revisit your trip history, maps, and statistics.

Choose the format that fits the way you sail. If you keep a digital logbook, consider how you’ll preserve access to important records and what backup arrangements make sense for your trips.

Frequently asked questions

What should a sailing logbook entry look like?

A useful entry records the date and time, position when relevant, course or route, speed, weather and sea conditions, crew, significant events, and any decisions that matter for understanding the trip. The exact details depend on the type of sailing and the purpose of the record.

How often should I make entries in a sailing logbook?

For a casual day sail, record departure, significant changes or events, and arrival. For longer passages, establish a regular interval appropriate to the conditions, vessel, crew, and applicable requirements. Some voyages are subject to specific record-keeping rules.

Can I keep a sailing logbook digitally?

Yes. Digital logbooks can help organize trip records, review routes, and attach notes or photos. Paper records can also be useful, especially as a backup. The appropriate choice depends on your needs and any requirements that apply to the vessel or voyage.

Are sailing logbook examples suitable for official records?

They can help you structure entries, but they are not a guarantee of compliance. Official requirements depend on factors such as the vessel, flag state, voyage, and applicable regulations. Check the relevant rules before relying on a personal template for an official purpose.

What’s the difference between a sailing logbook and a boat maintenance log?

A sailing logbook primarily records trips, navigation, conditions, and events during voyages. A maintenance log focuses on inspections, servicing, repairs, parts, and equipment condition. The two can complement each other, but one does not automatically replace the other.

Start with a simple, repeatable format

You don’t need a complicated system to maintain a useful sailing logbook. Start by recording when and where you sailed, the conditions you encountered, the significant events, and the decisions that shaped the trip.

Use these examples as a guide, adapt the fields to your sailing, and keep your entries factual and consistent. Over time, your logbook becomes more than a record of where you’ve been: it becomes a resource for understanding your experience and planning future trips.
