You know those yellow stickers on the boats that say something like “16 Persons or 2350 lbs?” One of the most common questions we get is, “Is ballast factored into those numbers?” or, in other words, “How many people is the boat rated for when the ballast is FULL?” This is an important question – probably more so than you might expect.

First, let’s talk about those ratings and where they come from – bear with me, this will all come together here soon. Most people think that those ratings are established by the Coast Guard,; however once a boat goes over 19 feet, the Coast Guard no longer gives specific ratings for capacity. The capacity ratings are, in most cases, established by a body referred to as the National Marine Manufacturers Association (NMMA). The NMMA is a governing body that ensures that boats built by participating manufacturers are up to certain safety standards, one [...]

There is No Replacement for Displacement

Building The Worlds Best Wakesurf Waves.

There is No Replacement for Displacement.

We are often asked why Centurion boats create such awesome surf waves.  There are multiple factors that combine together to make a world class surf wave, one of which is experience.  Centurion created its first surf boat hull way back in the 1990’s, way before surfing was the cool thing.  Additionally, there are things like CATS, Quicksurf and trim tab shapes that allow for wake customization and tweaking.  But the most important factor, by far, is displacement.  There is no replacement for displacement.

What do I mean by this?  Well, it’s simple; physics really does matter.  There are natural laws that apply to wave/wake size and shape.  The wave or wake of your boat (what you surf on) is created by your boat displacing water.  So, in basic terms, with all things being equal (the hull shape, size, etc. of the vessel), the boat and ballast combination that weighs the [...]
