Spending a day on the water is one of life’s greatest joys — but boating also means hours of exposure to intense sunlight. While strong winds or sudden rain might seem like your biggest challenges, the real danger often comes from the sun. Without proper protection, UV rays can quickly cause painful burns, accelerate skin aging, and increase your risk of skin cancer.

Why Sun Protection Matters on the Water

Unlike on land, there’s almost no natural shade when you’re out boating. Sunlight hits from above and reflects off the water’s surface, as well as white decks, sails, and hulls — doubling the exposure. The glare can be tough on both your eyes and skin, making sun protection an essential part of every boating trip. (Check out our guide on the best sunglasses for boating to protect your eyes, too.)

Essential Sunscreen Tips for Boaters

Sunscreen is your first line of defense against UV damage, and every boater should keep a bottle or two on board. Here’s how to make sure you’re getting the best protection possible:

  • Use SPF 15 or higher. SPF 15 is the minimum for meaningful protection, though SPF 30–50 is ideal for long days in the sun.
  • Look for “water-resistant” or “sport” formulas. These hold up better against splashes and sweat.
  • Don’t rely on SPF 50+. Higher numbers don’t necessarily mean stronger protection — frequent reapplication is more effective.
  • Choose non-comedogenic formulas. If you’re prone to breakouts or oily skin, pick sunscreens labeled “non-comedogenic,” meaning they won’t clog pores.
  • Protect your lips too. Use an SPF lip balm to prevent painful sunburn on sensitive skin.
  • Go broad-spectrum. Make sure your sunscreen protects against both UVA and UVB rays.
  • Store properly. Keep sunscreen out of direct sunlight — heat and UV exposure can make it less effective.
  • Apply early and reapply often. Apply 15 minutes before going outside and reapply every two hours (or after swimming or toweling off).

Pro tip: Always choose a reef-safe sunscreen when swimming, snorkeling, or boating in marine environments. Traditional sunscreens with oxybenzone and octinoxate can harm coral reefs and marine life.

Boating Hats: Shade You Can Count On

Even the best sunscreen won’t fully protect your scalp — which is why a good hat is a must-have for every boater. Hats help shade your face, neck, and ears while reducing glare.

  • Choose wide-brimmed hats for full coverage of your head and neck.
  • Secure your hat. Look for ones with chin straps or side eyelets to prevent them from flying off in windy conditions.
  • Avoid dark, heat-absorbing materials. Light-colored, breathable fabrics are ideal for staying cool.

Sun-Protective Clothing for Boating

As sunscreen wears off, lightweight sun-protective clothing can keep your skin safe and cool. Skip heavy cotton, which absorbs water and offers little UV protection. Instead:

  • Opt for UPF-rated fabrics. Many performance shirts and pants are made with UV-blocking technology.
  • Focus on coverage. Protect your neck, shoulders, and upper arms — the areas most exposed on deck.
  • Look for quick-dry materials. Synthetic blends or moisture-wicking fabrics are best for boating comfort.

Final Thoughts: Make Sun Safety a Boating Habit

Sunburns are painful, distracting, and can ruin your boating adventure. More importantly, repeated exposure can lead to serious long-term skin damage. By wearing sunscreen, choosing the right clothing, and staying shaded whenever possible, you can enjoy your time on the water safely.

Protecting your skin doesn’t just help you feel better — it ensures many more sunny days out on the water to come.
