Sustainable Sailing Tips: How to Protect the Sea While Cruising

As sailing enthusiasts, we all look for holidays where we can enjoy the natural beauties this world offers: the prettiest bays, the most colourful barrier reefs, the lushest vegetation, and the most turquoise waters.

But how can sailors be more environmentally friendly while enjoying such wonders? It's a question that matters more than ever. As the number of sailing trips increases every year, we must ensure we protect what we’ve come to admire.

We all need to take part in shielding our ecosystems and guaranteeing future generations a sustainable life. On vacations, it's easy to be distracted and commit minor blunders that may not appear to be significant but can be hazardous from a broader perspective.

Sail with the wind and switch off the engine

One of the easiest ways to reduce your carbon footprint while sailing is to use the wind instead of the engine. Hoisting the mainsail and unfurling the jib not only enhances the sailing experience—it also reduces your reliance on fuel, a key part of eco-friendly boating practices.

Always pay attention to the prevailing winds in your area, and sail only when it’s safe and manageable based on your skill level. If conditions demand it, don’t hesitate to use the engine responsibly—but remember that sailing was meant to be powered by nature!

Don’t throw anything overboard

Plastic pollution remains one of the top environmental concerns for sailing. We cannot overstate this: don’t throw anything overboard. Every year, marine species are injured or killed by entanglement or ingestion of plastics.

Instead, be part of the solution. Pick up litter when you see it, and dispose of it properly in the marina waste stations. Reducing waste on a sailboat begins with each of us taking responsibility for what we bring on board—and what we take off.

Minimise plastic usage

How to minimise waste and pollution on a sailboat? Start with provisioning. Avoid single-use plastic, and opt for reusable containers, biodegradable cutlery, and refillable water bottles. These changes may seem small, but when practised by many sailors, they make a huge difference.

This is one of the most effective sustainable sailing tips, and one that’s easy to adopt on every trip.

Correctly discharge grey/dark waters

Best eco-friendly practices for boat owners and charterers always include proper handling of wastewater. Grey and black water should never be discharged in shallow waters or near the shore. Use designated pump-out stations when available, or empty your tanks in deep offshore areas.

Be sure to know the regulations of each country you visit—many marinas have guides to help you comply with local laws and responsible boating guidelines.

Use eco-friendly sunscreens

What are the environmental concerns of sailing beyond plastic and fuel? Surprisingly, sunscreen. Many traditional formulas contain chemicals like oxybenzone and octinoxate, which damage coral reefs and marine life.

Choose reef-safe alternatives and consider wearing UV-protective clothing during peak hours. This small shift aligns perfectly with your goal of environmentally friendly sailing.

Switch to oars when using the dinghy

Engines—even small ones—add to ocean pollution. Switching to oars when going ashore is a great way to reduce your carbon footprint while sailing. Plus, it adds a bit of fun and exercise to your day!

For longer distances, consider using a modern four-stroke engine, which is cleaner than older two-stroke models. Either way, being mindful of fuel use is part of eco-friendly boating practices.

Use eco-friendly or homemade cleaning products

Sustainable sailing tips extend to everyday cleaning tasks. Commercial cleaning products often contain chemicals that harm aquatic life. Use eco-certified products—or make your own using vinegar, baking soda, and a few drops of essential oil.

This is a low-effort way to minimise waste and pollution on a sailboat while keeping your space clean and safe.

Be careful where you drop the anchor

Anchors can cause serious damage to delicate seabeds, like coral or seagrass meadows. Always anchor in sandy or muddy bottoms, and be cautious about depth and tide changes. These responsible boating guidelines help protect underwater habitats for future generations.

Be mindful of protected marine areas

More and more regions are establishing marine protected areas to safeguard biodiversity. If you’re wondering what some sustainable sailing tips for navigating these zones are, the answer is simple: follow the rules.

Check your charts, avoid restricted zones, and reduce speed or engine use where required. Respecting these spaces supports long-term marine conservation efforts and reflects true environmentally friendly sailing.

Remember: every little action matters. From reducing plastic use to choosing cleaner products and navigating responsibly, your choices at sea shape the future of our oceans. By embracing sustainable sailing tips and practising eco-friendly boating, you’ll not only enjoy the journey, but you’ll also protect the waters you love for years to come.
