Concise answer
The basic COLREGs (International Regulations for Preventing Collisions at Sea) every beginner on busy local waters should follow are: keep a proper lookout, proceed at a safe speed, understand who is the ‘give-way’ and who is the ‘stand-on’ vessel in common situations, use the correct lights and sound signals, and take early and obvious action to avoid collisions. Also check local harbour rules and berth/anchorage restrictions.
Useful practical points
- Keep a proper lookout: look and listen continuously — scan visually, watch AIS/plotter if fitted, and use a hand-bearing or binoculars in reduced visibility. Vigilance is your first line of defence.
- Safe speed: sail or motor at a speed that lets you stop or manoeuvre to avoid a collision — slower in crowded areas, near shore, or in restricted visibility. Safe speed depends on conditions, not a fixed number.
- Give-way vs stand-on: in most crossings, the vessel that has the other on her starboard (right) side gives way; power gives way to sail in many close situations (but not always — see explanation below). When you are the give-way vessel, keep clear and make a positive, early manoeuvre.
- Overtaking: any vessel overtaking must keep clear of the vessel being overtaken. Good lookout and clear communication are essential.
- Head-on and reciprocal situations: if two power-driven vessels are approaching head-on, both should alter course to starboard (right) to pass port-to-port when safe. Give a clear, early alteration.
- Lights and sound signals: know the basic light configurations (masthead, sidelights, sternlight for power; red/green sidelights and sternlight for sail making way) and basic sound signals in restricted visibility or when communicating a manoeuvre.
Why this matters
Following these basics reduces the chance of collision and helps other skippers predict your actions. Busy local waters often have mixed traffic (sailboats, powerboats, ferries, commercial traffic, kayaks), so predictable, early, and obvious actions keep everyone safer.
Common beginner mistakes
- Waiting too long to act; late small corrections are often insufficient and confusing to others.
- Assuming sail always has right of way — propulsion type, windward/leeward position and the situation change the responsibilities.
- Not using sound or VHF to clarify intentions when visibility or traffic density makes rules uncertain.
One practical next step
If you haven’t already, review the official COLREG diagrams and local harbour bylaws: start with the Australian Maritime Safety Authority (AMSA) guidance and your local harbourmaster’s notes for any area-specific rules. Practice basic scenarios (crossing, overtaking, head-on) on a training sail with an experienced skipper so the rules become instinctive.
Terminology (plain English)
- Give-way vessel: the boat that must alter course or speed to avoid collision. Make clear, early moves.
- Stand-on vessel: the boat that should maintain course and speed but must manoeuvre if the give-way vessel fails to act.
- Port/starboard: left/right of your boat when facing forward. Port = left, starboard = right.
- Making way: a vessel is making way when it is moving through the water (under sail or power). If not moving (e.g. anchored), different rules apply.
