Summer sailing is pure joy! Nothing compares to the feeling of navigating through crystal-clear waters, feeling the warm breeze on your skin, and getting to explore endless anchorages. But when temperatures soar, it can quickly become dangerous. This year, the Med has been hit hard by unprecedented heatwaves, and it’s more important than ever to sail smart and stay safe.
To help you adapt and brace for warm temperatures, we have put together 7 essential tips to protect yourself, your crew, and your boat this summer. Here’s how to stay safe while sailing during a heatwave.
Sailing during a heatwave
1. Stay hydrated
This may seem like a given, but drinking water regularly and more than you think you need is crucial. Indeed, your body loses fluids faster under high heat. Remember that feeling thirsty means you’re already dehydrated, so drink water regularly! Eating hydrating foods like fresh foods and vegetables is also recommended. When sailing, make sure you have enough water on board in case of emergency.
2. Wear SPF
At sea, the sun is stronger than on land, and UV exposure is constant. Make sure you wear reef-safe and high-SPF sunscreen, and remember to reapply every 2 hours.
Beyond sunscreen, the right clothing can also make a difference. Opt for lightweight and breathable fabrics, with light colors that will help reflect sunlight. For maximal protection, shield your face with a hat and sunglasses. Don’t forget: shade is your best friend when sailing during a heatwave!
3. Rethink your routine
The best way to sail during a heatwave is to adapt your schedule. So, avoid sailing during the peak heat window, typically between 12 and 5pm. Instead, sail earlier in the morning and plan low-effort activities like naps and swimming for the afternoon. Additionally, try to keep your cabin as cool as possible by ventilating with fans, wind scoops, or solar-powered ventilators.
4. Protect your boat too
High heat isn’t just a human issue, your engine and electronics feel it too. Indeed, high temperatures can affect electronics and engine cooling systems. Monitor them closely and make sure to turn off electronic equipment when you don’t need them so they don’t overheat.
5. Recognize a heat stroke
A heat stroke is a serious emergency, and it can be life-threatening. Therefore, it is important to recognize the signs, which include:
- dizziness
- nausea
- flushed or dry skin
- rapid heartbeat
- confusion
- fainting
If these symptoms occur, act immediately. The top priority is to lower the body temperature. Place the person in the shade, give them sips of water and apply cool compresses (not cold!) to their neck, armpits, and wrists. Do not place the person directly into water, especially cold, as this can cause a shock that can lead to heart failure. Finally, call for medical help immediately.
6. Keep your pets safe
Our pets are even more vulnerable during high temperatures. They are at high risk of a heat stroke. To keep them as safe as possible, only bring them on board in the morning, and keep them cool at all times, especially during peak heat hours. Watch out for their paws as well, as your deck can burn their paws. Want expert advice? Check out our veterinarian Q&A on keeping your pets safe on board!
7. Stay informed
Monitor weather apps to track temperatures and heatwave alerts. Also, be aware of fire risk levels and don’t light campfires during a stopover! Most importantly, do not take risks and listen to your body! With a little planning and the right precautions, you can enjoy every minute of summer on the water, even in extreme heat.
This is the end of our article on how to stay safe while sailing during a heatwave. By following these tips, we hope you will be able to both safeguard yourself and your crew, and also ensure an enjoyable and memorable summer sailing experience!
Stay cool, sail smart, and enjoy the Med responsibly!
