When scientists increased the height of the waves in the flow channel by moving the paddle more violently they observed that the waves became very steep and collapsed forming a breaking wave. However, regular waves do not threaten a well found yacht unless the yacht is permitted to surf down the forward face and reach a high speed. Of course this is why pendulums were used for clocks.įrom these studies we can obtain an effective engineering understanding of regular waves. Thus waves formed of liquid lead would have the same speed as water wavesĪ pendulum would have the same period if the weight were lead or brass. Where A and B are constants and L is the wave length and pendulum arm length. Period of a wave = A L seconds Period of a pendulum = B L seconds. In fact the formula for the period of a simple pendulum is remarkably similar to that of a wave. Note that the weight of the water or the weight at the bottom of the pendulum has no effect on the period of either a wave or a pendulum. The mass of waters moving up and down is the weight and the wave length is similar to the length of the arm of the pendulum. These simple relationships help us understand that waves are packets of energy floating on the water surface. (23 knots) and a period between wave crests of 7.7 seconds.įor regular waves the wave height does not affect the wave speed. Knowing and practicing these five important safety tips and employing them regularly will go a long way to keeping you and your crew safe on the water.Thus a wave with a wave length of 300 ft. ONCE YOU’VE CROSSED THE WAKE, RE-ACCELERATE TO RETURN THE BOAT BACK ON PLANE. By staying parallel to the other boat, it also keeps you positioned correctly on your side of the channel. This allows the boat to “roll” a bit over the wake … vs “jumping over” it. APPROACH THE WAKE AT A 45 DEGREE ANGLE.ĭo NOT turn into the wake, but continue heading parallel to the other boat. This “bow high” position also reduces the chance of “diving the bow” onto the second wave. This will lift the bow up and help to create a “cushioned effect” on the wake. If your boat is on plane, reduce your speed to where the boat just comes off plane. Be sure to stay within the channel and be aware of other boat activity in the area. The further you are away from the boat that is producing the wake, the smaller the wake becomes. MOVE OUT AWAY FROM THE WAKEĭo this as safely possible. Make sure they are all securely seated and aware. The minute you realize you will be crossing a wake, let your passengers know. Let’s talk about what you can do to safely cross the wake of another boat, as this knowledge will hopefully inspire greater confidence when you’re at the helm and taking responsibility for the safety of your crew. Did you know that improper wake crossing is the second leading cause of personal injury to boaters and their guests, following only behind dock-related injuries sustained by falling during boat entry or exit? Improper wake crossing due to high speeds (which is the biggest problem) or approaching the wake from the wrong angle can result in serious injury including spinal compression and disc hernias, among others. #Reduce speed and head into the waves at 45 degree angle how toOne of the most important lessons we teach our members is how to safely approach and cross the wake of another’s boat.įor many newer boaters, “crossing over” the wake is a scary proposition, and for good reason. Our goal is to ensure our members are both safe and confident on the water. Every member goes through classroom and 1:1 on-water training with our captains before taking out a boat for the first time. At Freedom Boat Club, we are major advocates and teachers of boating safety.
