Safe Anchoring Practices Course
This course prepares you to anchor efficiently and safely in a wide range of conditions. You will learn to assess the risks of an anchorage, choose the right spot by reading the chart, the seabed and the weather, select and prepare anchor, chain and rode, carry out the maneuver with a well-briefed crew, confirm that the anchor is holding, keep a proper anchor watch and respond to dragging, a fouled anchor or a change in the weather, while protecting sensitive seabeds.

What is the Safe Anchoring Practices Course?
This short course focuses on the seamanship of anchoring for skippers, deck crew and boat operators, from a lunch stop in a sheltered cove to a night at anchor in an open bay. You will study the difference between temporary, overnight and emergency anchoring, mooring buoys and berthing; the components of the ground tackle; common risks such as dragging, collision and lost anchors; how depth, seabed, weather, current and swinging circle interact; how to read charts, plotter and echo sounder to choose a permitted, sheltered anchorage clear of channels, cables and protected areas; anchor types and basic sizing of chain and rode; and the full maneuver from approach to weighing anchor.
What sets this course apart: it is centered on the decisions and the maneuver rather than on the mechanics of the windlass, which is covered in a separate equipment course; it gives clear criteria for choosing, changing or abandoning an anchorage when conditions become unsafe; it pays special attention to checking holding with visual references, GPS and chain tension, and to anchor alarms and watch rotas; it includes respect for seagrass meadows and other sensitive seabeds; and it closes with an applied project in which you plan the anchoring, watch and contingency procedures for a real or realistic anchorage.
Program highlights
- Anchoring fundamentals: temporary, overnight and emergency anchoring, buoys and crew responsibilities.
- Choosing the anchorage: permitted areas, seabed type, shelter, swell, current and swinging room.
- Ground tackle: plow, Danforth, Bruce, Rocna and grapnel anchors, chain, rode and snubbers.
- The maneuver: approach, letting go, scope, setting the anchor and checking that it holds.
- Anchor watch: alarms, chart marks, shore transits, watch rotas and position logging.
- Contingencies: dragging, fouled anchor, change of weather and protection of the seabed.

Fundamentals of safe anchoring, vessel stability and risk prevention
- 1.1. The concept of anchoring and the differences between temporary anchoring, overnight anchoring, emergency anchoring, mooring to a buoy and berthing
- 1.2. The role of the anchor, chain, rode, windlass, cleats, bow roller, shackles and connecting elements of the ground tackle
- 1.3. Common risks: dragging, collision, loss of the anchor, damage to the seabed, fouled lines, poor spacing and wind shifts
- 1.4. The relationship between depth, seabed, weather, current, swinging circle, anchor weight and the safety of the vessel
- 1.5. Responsibilities of the skipper, crew and passengers during the anchoring maneuver
Choosing the anchorage, reading the surroundings and assessing conditions
- 2.1. Identifying permitted areas, restricted areas, navigation channels, protected areas, cables, pipelines and sensitive seabeds
- 2.2. Assessing depth, seabed type, slope, shelter, swell, current, wind and the space available for swinging
- 2.3. Reading nautical charts, plotter, echo sounder, coastal references, buoys, signs and local notices
- 2.4. Safe distances from other vessels, the coast, rocks, swimmers, buoys, harbors and passing traffic
- 2.5. Criteria for choosing, changing or abandoning an anchorage when conditions become unsafe
Anchoring equipment, preparation, basic sizing and preventive maintenance
- 3.1. Types of anchor: plow, Danforth, Bruce, Rocna, grapnel and lightweight anchors, and selection criteria by vessel and seabed
- 3.2. Chain, rope, mixed rodes, shackles, thimbles, carabiners, snubbers and safety elements
- 3.3. Basic sizing according to length, weight, expected wind, depth, type of seabed and duration of the stay
- 3.4. Pre-use checks of windlass, brake, gypsy, electrical connections, chain stowage, length markings and bitter-end attachment
- 3.5. Maintenance of anchor, chain, ropes and fittings: rust, wear, deformation, chafe and load points
The anchoring maneuver, letting go, checking the hold and keeping watch at anchor
- 4.1. Preparing the maneuver: roles, communication, reduced speed, approach to the chosen spot and control of the bow
- 4.2. Letting go the anchor, amount of chain or rode, scope ratio, gentle astern and progressive setting
- 4.3. Checking the hold with visual references, echo sounder, GPS, chain tension, vibration and the behavior of the boat
- 4.4. Monitoring the swinging circle and watching for changes in wind, current, tide, traffic and nearby vessels
- 4.5. Use of anchor alarms, chart marks, shore transits, watch rotas and position logging
Applied project in safe anchoring practices
- 5.1. Definition of the case: daytime anchoring, overnight anchoring, sheltered cove, open bay, emergency, recreational boat or passenger trip
- 5.2. Diagnosis of the anchorage: depth, seabed, shelter, wind, current, tides, restrictions and nearby hazards
- 5.3. Choice of anchoring equipment, length of chain or rode, crew roles, communication and preparation of the maneuver
- 5.4. Design of the procedure for letting go, checking the hold, keeping watch, alarms, swinging circle and criteria for leaving
- 5.5. Preparation of the plan for weighing anchor and responding to dragging, a fouled anchor, a change in the weather and protection of the seabed

Questions about the Safe Anchoring Practices Course
Skippers, deck crew, charter and passenger boat operators, nautical students and boaters who want to anchor more safely and confidently in different conditions.
That course focuses on the mechanics, installation and maintenance of windlasses and ground tackle. This one focuses on seamanship: choosing the anchorage, carrying out the maneuver, checking the hold, keeping watch and handling contingencies.
Yes. You will work with scope ratios and the factors that change them, such as depth, seabed, expected wind and the length of the stay, and see how they affect your swinging circle.
The course explains how to detect dragging early with alarms, transits and GPS, and how to respond safely, re-anchoring or leaving the anchorage, and includes procedures for a fouled anchor and a sudden change in the weather.
Yes. You will learn to identify protected areas and sensitive seabeds such as seagrass meadows and to choose spots and techniques that avoid damaging them.
No. The course is delivered online through case studies, chart work and planning exercises, which you can then apply on board with your own boat or crew.
Through exercises in each module and a final applied project in which you plan the anchoring, watch and contingency procedures for a specific anchorage.
