Tips for Safe Boating in Rough Water

When you think of summer, you probably think of blue skies, sunshine and boating in the water, but with the good weather also comes the bad. Storms can make water not only difficult to navigate but also extremely dangerous. Don’t get caught out on the water in a storm without knowing how to safely boat through rough water.

Preparing for the possibility of boating during rough weather

One of the most crucial parts of boating in bad weather is to follow your emergency plan, but this only works if you have one. Even if the weather forecast predicts blue skies and sun all day, there is still a chance of changing weather over the water. Think of your bad weather plan as the fire escape plan for the water. Ensure you have enough life jackets on the boat each time you leave your boat dock. If you have a co-captain or additional passengers, identify before you depart who has which duties in the event of dangerous weather or large waves. Other useful items to always have on your boat include:

  • VHF-FM Marine Radio

  • Nautical charts, especially if you are unfamiliar with the area you are boating in

  • GPS/Radar

  • Life ring

  • Distress signals for both day and night use

Understanding warnings and advisories from the U.S. National Weather Service

The U.S. National Weather Service (US NWS) will set warnings for wind speed but these only help if you know what they mean. Marine warnings are broadcasted in the unit of Knots or a nautical mile. One knot is equivalent to 1.15 mph. Learn the terms the NWS uses to classify wind speed:

  • Light winds are 1-14 knots or 1-16 mph
  • Moderate winds are 15-19 knots or 17-22 mph
  • Strong winds are 20-33 knots or 24-37 mph
  • Gales are 34-47 knots or 39-54 mph
  • Storms are winds of 48-63 knots or 55-73 mph
These wind warnings directly correlate with the weather warnings broadcasted by the US NWS:
  • Small craft warnings are issued when winds are either light, moderate or strong
  • Gale warnings are issued when winds are predicted to sustain 34-47 knots
  • Storm warnings are issued when winds are expected to sustain 48-63 knots

Learning the signs of changing weather

Wind, water currents, and barometric pressure can help you not only predict the weather, but understanding these things can assist you in navigating the water as well. The higher the wind speeds, the stronger the currents and waves will be and could prove to be the biggest issue you face when boating on rough water.

Buy a barometer and learn how to read it. Incoming weather can be identified by the changes in barometric pressure, even before a weather advisory is posted if applicable. Take a reading of the barometer every 6 hours or so, and identify any changes present, if any.

If you get caught in a storm, use these tips to help you navigate and identify where the storm is coming from and going to:

  • Do not ride into the storm’s center. If you don’t know how to find a storm’s center, stand with your back to the wind and the center will be to the left.
  • Low clouds pose a more imminent threat. Low clouds are usually from local, close-by storm cells where high clouds are associated with a system up to 6 hours away.
  • Pay attention to wind direction. If winds change in a clockwise direction, you can expect fair weather however a counterclockwise change indicates a storm’s approach.
  • Identify where the clouds are. If there are storm clouds in the east or south, storms are leaving the area but clouds in the north and west could mean you are in the storm’s path.
  • Listen to thunder. The sound of thunder tells a lot about how close or far a storm may be. If the thunder is a rumble like a timpani the storm is off in the distance. A crash and band thunder means the storm is nearby.

Being out on your boat or PWC in rough water

Not only do thunderstorms create strong winds, large waves and heavy rain but lighting too. Because there are no advisories dedicated to the presence or abundance or lighting, it is imperative to keep an eye on the sky and looking for lighting leading up to or during a storm. Lighting can create catastrophic damage to your watercraft as well as result in fires and loss of electricity. If possible, remain in the cabin of your boat until the storm passes and avoid coming in contact with electrical devices.

Avoid driving through the actual storm if at all possible. You risk the possibility of capsizing, losing electricity, damaging your boat and more. Having a plan of action before leaving your floating boat lift will help you identify possible ports for you and your crew to ride out the storm.

If the waves and rough water are dissociated from a storm, proper training will be your best friend when navigating and driving.

  • Reduce your speed
  • Watch for debris and other watercrafts
  • Pump out bilges to keep the boat high in the water
  • Head the bow into waves at a 45-degree angle
  • Drop anchor from the bow if the engine stops

Docking your boat in rough water

Ask any captain, docking a boat can be one of the most difficult parts of the boating experience, but even more so with unpredictable waves and winds. Investing in floating jet ski docks, floating boat docks and mooring accessories will help you safely dock your boat in high or rough water. Floating docks with long pilings are ideal for docking your boat or PWC in rough waters as they are able to handle the surges that come with bad weather. However, if you are docking your boat at a floating dock rather than a mooring, secure your ties to the highest part of the piling as your boat will be more secure than if tied to the floating dock itself. If you are worried about chafing whether it’s against another boat in the marina or against other docks, reinforce your lines by using ground tackle and anchoring your boat down.

With the proper preparation, knowledge and training, you will be ready to face rough waters if need be.
