When it’s hazy, hot, and humid, jumping on a boat and zipping across the water is a great way to cope. But let’s do it safely. Summer heat can creep up on boaters and take a toll. Here are six tips to stay safe during the dog days of summer.

1. Go for sun protection.
Dress for success with UPF (Ultraviolet Protection Factor) clothing. Choose lightweight, sweat-wicking, long-sleeved shirts. Reapply sunscreen more often than you think you need and remember to bring a hat and sunglasses. For even more protection, outfit your boat with a bimini or temporary sun cover. Direct sunlight can make the air feel 10 to 15 degrees warmer.
2. Hydrate early and often.
Planning to spend the weekend on the water? Don’t wait until you’re hot and thirsty on Saturday afternoon; start hydrating on Friday. Provision your vessel with plenty of water and water-laden snacks such as fruit. Consider stowing some electrolyte powder mixes, too. They are lightweight, don’t take up much room in the galley, and can help boost hydration.
3. Be heat smart.
Heatstroke occurs when the body temperature increases significantly (generally above 104 degrees Fahrenheit). Telltale signs include headache, nausea, vomiting, confusion, agitation, irritability, and even seizures. Immediately move the victim to a cooler environment, either indoors or in the shade. Wet them with cool water or use ice packs, especially on the head, neck, armpits, and groin. Seek immediate emergency medical attention by calling 911 or hailing the Coast Guard on your marine radio.
4. Be weather-wise.
In the summertime late afternoon and evening pop-up thunderstorms are always a possibility on the Bay. Keep an eye on your favorite weather app, and, just as importantly, keep an eye toward the sky. Ensure your onboard or hand-held VHF is operational and bring your cellphone, keeping it dry and charged, in case you need to call for help. Before slipping the lines, file a float plan and pick out a couple of safe harbors that you could shoot to in a hurry if needed.
5. Take a swim!
Boaters can take advantage of the best way to stay cool—jump in! Just don’t jump off a moving vessel or where there is heavy boat traffic or at any place that could have hidden objects under the water. Find a safe, out-the-way anchorage and drop the hook.
6. Look out for jellyfish!
When the heat arrives, jellyfish usually do too. You may find it’s a good time to cruise to the Northern Bay, which is usually nettle-free due to more freshwater and lower salinity. Another idea is to use a Nettle Net boat pool to create a jellyfish-free swim area. If you do get stung, tried-and-true home remedies include rinsing with salt water or vinegar and applying meat tenderizer or baking soda.
During heavy jellyfish infestation periods these pesky creatures can actually clog a boat’s sea strainer for the AC or engine freshwater intake, so it’s a good idea to check your strainers regularly.
