As some of you know, I have my Bachelor’s Degree in Physics. When new hulls are released, both on our brands of boats and our competition, the first thing I do is crawl underneath the boat to see what is going on. Why a wakeboard boat rides the way it does and why it produces the wake it does is all hydrodynamics. Unless you are familiar with the laws of hydrodynamics, the lines and curves on the bottom of the boat may not mean much to you. That is what I am here for, to explain why according the the laws of Physics, our hulls and wakes are scientifically proven to be better.
Let’s start with what makes a boat hull ride the way it does. There are many key features on a hull that make a wakeboard boat perform; these include strakes, pockets, keels, chines, hooks, wakeplate, cavitation plates, etc. The placement of all of these elements can make a boat ride dramatically different, therefore, causing the wakes to be different.
There are a few key features that the boats we sell have that make them the superior boat on the water. Starting at the front of the boat, you want this section to be very deep to cut through choppy water and to help provide better tracking. Many I/O runabouts have very deep V hulls, such as Sea Ray and Cobalt, that make them ride very well in rough water. Companies such as these, unfortunately, extended the V all the way towards the back of the boat and destroys the wake. Take a look at Supra’s deep V keel, the deepest V in the industry.
Notice that a big portion of the keel is under the straight black line. This give this boat a very good rough water ride.
From there, you have the middle section of the hull. There is a lot of techincal stuff that takes place here so I won’t spend too much time on it. Basically, this is where you want the hull to start flattening out to start forming the wake.
This takes us to the back 1/3 of the hull. According to the laws of hydrodynamics, when water travles up a surface it creates natural suction. If it travels down a surface, it gives the boat lift. Lift is NOT what you want on a wakeboard boat. It is however what you want on a ski hull. Lift produces a small and rounded wake.
Take a look at this Tige hull:
Notice the dramatic slope up at the last 1/3 of the hull. This is going to give this hull suction and produce a bigger wake easier. Some wakeboard hulls have little to no slope and suprisingly, some even have a “hook” at the end.
Take a look at these pictures of popular wakeboard boats. These pictures are taken directly from the company’s website so no alterations have been made. The black or green line was drawn from the center most tracking fin to show a straight line. Suprisingly, some of these “flagship” wakeboard boats didn’t even have tracking fins so we did the best we could with the starting point of the straight line.
From the pictures, you will see what Moomba, Supra, and Tige have the most deep V under the straight line in the keel and the most upward slope in the last 1/3. That proves that our boat will have the best ride and naturally produce the biggest and best wakes. You will clearly see that boats that might not give you the best rough water ride and must use other means from producing a wake.
