Level Flotation

If you want the highest grade flotation, choose level flotation, because it gives you the best chance possible of staying upright and balanced should water get inside your boat.

The further a vessel's flotation is placed away from its centre of gravity, the more stable the boat will be for the crew to stay aboard, if flooded, instead of being capsized.

With this in mind, Waveriders have been designed so that flotation can be placed in the most stabilising location possible: the sides of the hull.

On the other hand, even a small amount of water in a boat with "positive" or "basic" flotation increases instability and the risk of capsizing. Why? Because often it's in areas like under the floor, and air always seeks to be above water.  Basic and positive flotation is there to keep a part (like the tip of the bow) of a sinking boat above the surface, for later retrieval. Not for your survival.

Stable at rest

Like buoyant "feet" all around you, your footprint in the water is maximised in a Waverider.

Of course, this is why catamarans are so stable - they're wide at the waterline. However, wide mono-hulls usually have to sacrifice speed and performance to get stability, or get a bigger outboard, because so much more boat has to be pushed through the water which requires a bigger horsepower engine. See below to discover how a Waverider throws this on its head!

The width of a Waverider is so similar to catamarans of the same length that many people have compared the stability to a cat ... or a far bigger craft.

But it's not just it's width that makes Waveriders so stable. It's that big downward facing reverse chine. The deep, flat angles slow the sideways motion as the boat dips to the side, like when crew come aboard. Similar to pulling your cupped hand through deep water, the Waveriders also resist side-ways motion.

 

Stable on sharp turns

Waveriders resist banking/tilting during turns, because two design features work together to keep you level.

First, each reverse chine creates lift, forcing upward pressure on the side that usually banks, especially at speed.

Second, the wings of the reverse chine act like surfboard fins, encouraging forward motion and resisting sideways slip/slide.  This is a great safety benefit as it prevents loss of control and subsequent capsizing.

Remaining level during turns means that the boat's footprint in the water does not alter shape, allowing you to maintain speed. Alternatively, a banking boat tilts, so that the hull behaves like a flat bottom barge, pushing water, requiring more throttle to maintain speed.

Notice in the photos, the curved wake shows the sharpness of the turn, yet the boat is very level.

Hydrodynamic Lift, to soften the ride

The huge reverse chines under each side of your Waverider hull means you have a firehose of resistance against tinnie bang.

Hydrodynamic lift is created from the hydrofoils built into your hull (the huge reverse chines). Unlike other monohulls, water is harnessed and manipulated (pressurised) to create lift and slow downward impact.

The smooth riding of Waveriders have been compared to fibreglass boats, when it comes to comfortable journeys. Quite the irony, given Waveriders ride higher in the water than most tinnies, and a lot higher than most fibreglass boats. A bonus is, the less a boat needs to be pushed through the water, the less throttle and fuel you need.

STABLE WITH CONTROL ON SWELLS

The design technology behind a Waverider's ability to actually "ride waves" makes them safer than any other boat.

  1. First, the reverse chine is a very specific angle and width which makes them have a similar function to surfboard fins. Without fins, a surfboard slips and slides on waves, allowing no control to the rider. In the same way, without the "wings" of a Waverider hull, a standard boat can do the same thing.
  2. Second, the beaminess of the hull is such, that the stability is truly trustworthy.
  3. Third, the reverse chine is carried all the way to the bow and stays just as radically wide as the sides. The distinctive "step" at the bow uses powerful hydrodynamic lift to force the nose out of a trough and prevent nose-diving & broaching.

These three features are an ecosystem, each working together and relying on each other when you find yourself driving towards a swell or with a swell at your back.

More floor space

The floorspace of a Waverider goes right over the wide reverse chine, and the flotation in the sides is raised to make space for your feet. So, you can stand right at the edge, not just because there's room to, but because the boat's stable enough to let you ... with others.

A bonus of the flotation-filled sides is that the vertical lining makes for a comfortable fishing spot, since you can lean your weight on it. Notice the diagram of the regular monohull -- the sides slope away from you, so you can't use them for steadying yourself against.

LEVEL FLOTATION

To resist capsizing if swamped.

WIDER FOOTPRINT

For catamaran-like stability. 

WIDE REVERSE CHINE

For the softest of rides, comparable to heavy fibreglass boats.

TOP STRUCTURE DESIGN

Now that we've covered the substructure of the hull design, we'll move on to the upper deck designs.

You have 2 choices: the Classic or the Luxe.

475_2018 model_side view

CLASSIC STYLE

The Classic style features the timeless arching rise of the gunwales towards the bow, complete with a straight-back transom. The inside main deck is pushed as far forward as possible while still allowing for a small casting deck at the bow for maximum usability.

LUXE STYLE

The Luxe style features upward-arching gunwales that slowly taper flat at the bow. A larger casting deck is supplied and the style is complimented with a fast back transom pod and either inbuilt steps or fold down steps that form part of the transom.

Waverider, 450 Bowrider

Both the Classic and the Luxe style Waveriders are available in several layout options. See our Range for more information.
