What is a NOAA Small Craft Advisory?
A NOAA Small Craft Advisory is a weather advisory issued by the National Oceanic and Atmospheric Administration (NOAA) when hazardous weather conditions pose a threat to small boats. These conditions may include high winds, rough seas, and a risk of coastal flooding.
When is a NOAA Small Craft Advisory issued?
A NOAA Small Craft Advisory may be issued when hazardous weather conditions are expected or are already occurring.
What are the dangers of a NOAA Small Craft Advisory?

What does NOAA consider a small craft?
Small Craft Advisory
A Small Craft Advisory (SCA) is a weather advisory issued by the National Weather Service (NWS) when hazardous conditions are expected for small boats. A Small Craft Advisory may be issued for winds, waves, and/or tides that are hazardous to small boats.
The specific criteria used by the NWS to issue a Small Craft Advisory varies from place to place, but typically a Small Craft Advisory is issued when winds are expected to reach 20 to 33 knots (23 to 38 mph), or when waves are expected to reach 4 to 5 feet (1.2 to 1.5 meters), or when the tidal range is expected to reach 6 feet (1.8 meters) or more.
Small Craft Warnings
A Small Craft Warning (SCW) is a more serious weather advisory than a Small Craft Advisory, and is usually issued when hazardous conditions are expected for small boats and larger vessels alike. A Small Craft Warning may be issued for winds, waves, and/or tides that are hazardous to both small boats and larger vessels.
The specific criteria used by the NWS to issue a Small Craft Warning varies from place to place, but typically a Small Craft Warning is issued when winds are expected to reach 34 knots (39 mph) or more, or when waves are expected to reach 6 feet (1.8 meters) or more, or when the tidal range is expected to reach 9 feet (2.7 meters) or more.
What size vessel is considered a small craft?
A small craft is a vessel that is typically less than 26 feet in length and is not intended for overnight voyages. Small crafts are often used for fishing, recreation, and other activities on inland waterways and coastal areas.
The size and design of small crafts can vary greatly, and there is no single definition for this type of vessel. However, small crafts are generally considered to be less seaworthy and less equipped than larger vessels and are not suitable for long-distance travel.
Small crafts are often used for fishing, recreational boating, and other activities on inland waterways and coastal areas. They are typically less than 26 feet in length and are not intended for overnight voyages.
Small craft can be powered by a variety of engines, including gasoline, diesel, or electric motors. They may also be fitted with a variety of accessories, including fishing gear, canopies, and seating.
In general, small craft are less seaworthy and less equipped than larger vessels. They are not suitable for long-distance travel and should be used with caution in rough seas.
What conditions create a Small Craft Advisory?
What conditions create a Small Craft Advisory?
A Small Craft Advisory is issued when winds between 18 and 33 knots and/or seas between 6 and 11 feet are expected. These conditions can make small boats, kayaks, and canoes dangerous to operate.
What is the wind speed for a small craft?
Wind speed is an important consideration for small craft operators. Knowing the wind speed can help with decisions about sailing, mooring, and landing.
Wind speeds are typically classified into one of five categories, which are:
Light air – 0-6 mph
Breeze – 7-12 mph
Gale – 13-18 mph
Storm – 19-27 mph
Hurricane – >27 mph
For a small craft, wind speeds of less than 10 mph are generally considered light air, wind speeds of 10-15 mph are considered a breeze, wind speeds of 16-25 mph are considered a gale, and wind speeds of >26 mph are considered a hurricane.
Which of the following flags is used to indicate a Small Craft Advisory?
Which of the following flags is used to indicate a Small Craft Advisory?
The Small Craft Advisory flag is a yellow flag with a black square in the center. It is used to indicate a hazardous marine condition for small boats.
What is gale force winds mph?
What is gale force winds mph?
A gale is a very strong wind, usually with a speed of at least 34 knots (39 mph, 63 km/h). The term is often used interchangeably with the word “storm”. A gale force wind is a wind with a speed of at least 48 knots (55 mph, 89 km/h).
The Beaufort scale is a measure of the intensity of wind speeds. The Beaufort scale ranges from 0, which is calm, to 12, which is a hurricane. A gale is classified as a Beaufort scale of 6 to 8.
Gale force winds can cause damage to property and can be dangerous to people. They can also cause problems for transportation, such as with air travel and shipping.
What size boat is small?
When it comes to boat sizes, there is no definitive answer. It really depends on your needs and what you plan to use the boat for. That said, there is a range of boat sizes that can be classified as small.
For recreational use, small boats generally range in size from 10 to 18 feet long. They are often easy to manage and can be transported on a trailer. Small boats are ideal for fishing, sailing, or cruising on a calm body of water.
If you are looking for a boat that can handle a bigger body of water, or if you need more space for passengers or gear, you may want to consider a larger boat size. However, it is important to remember that larger boats come with additional costs and responsibilities, such as fuel costs, storage, and maintenance.
Ultimately, the size of the boat that is right for you depends on your needs and budget. So do your research, talk to boat dealers, and ask questions to find the boat that is perfect for you.
