Define “small craft advisory”

Sailors at the ASA 103 level should pay attention small craft advisories. These are issued by the National Weather Service and broadcasted by NOAA Weather Radio during hazardous wind and sea conditions.

What is a Small Craft Advisory?

Ever dreamed of setting sail on a calm, sunny day, only to be met with choppy waves and gusty winds? If you’re a boater, encountering a Small Craft Advisory (SCA) can quickly turn your dream into a nightmare. But what exactly is an SCA, and how can you stay safe when one is in effect?

Think of an small craft advisory as a friendly warning from the National Weather Service (NWS). It’s issued when winds are expected to reach speeds between 20 and 33 knots (23 to 38 mph), or when waves are predicted to be 5 to 8 feet high (or even higher in some regions). These conditions can be hazardous, especially for smaller vessels like kayaks, fishing boats, and pleasure craft.

While an small craft advisory isn’t as severe as a gale warning or hurricane warning, it’s still important to take it seriously. Here’s why:

  • Rough seas and strong winds can capsize your boat. Even experienced boaters can be caught off guard by sudden changes in weather.
  • Reduced visibility and choppy waters make navigation difficult. You might end up lost or run into other boats.
  • The risk of hypothermia and injuries increases. If you’re thrown overboard or your boat takes on water, being in cold, rough seas can be dangerous.

So, what should you do if you encounter an small craft advisory?

  • Stay informed! Check the latest marine forecast before you head out, and monitor weather conditions closely.
  • Heed the warning! If an SCA is in effect, postpone your boating trip. It’s better to be safe than sorry.
  • Never go out alone. Always have another person onboard, and let someone know your planned route and expected return time.
  • Make sure your boat is seaworthy. Have all necessary safety equipment, including life jackets, flares, and a VHF radio.
  • Dress for the conditions. Wear warm clothes and a life jacket, even if it’s a sunny day.

By understanding and respecting Small Craft Advisories, you can ensure your boating adventures are safe and enjoyable. Remember, the ocean is powerful, and it’s always best to err on the side of caution. So, stay informed, stay safe, and happy sailing!
