Shred Master ride plates, best of all, it's a truly unique unit, not just a slightly reworking of a product currently on the market.   A natural "V" shape and whether they're the only company to hand finish their products or not, those products definitely work.                                                                       Personal Watercraft Illustrated Magazine





    This is a special order ride plate, watercraft that is no longer in production we do not stock ride plates for.   Plus handmade the way we make them takes between 6-8 hour each to make from casting to finish.   At times it can be up to 10 BUSINESS days before shipping some busy times of the year even longer.

Extremely Ultra Important        

This ride plate produces a 100% straight high speed tracking line in all water conditions.  This is crucial due to the Ultra's fast speed yet lack of handing control especially in rough water.  And essential for once the Ultra leaves the water (boat wake hop, etc) this V" bottom ride plate commands an imperative straight tracking line immediately upon water contact (no squirliness, drift or 90 degree unwanted out-of-control high speed Ultra hull possessed hook turn) just hammer down action now!   

      No other handling component can accomplish this function!  Not sponsons (which are out of the water on a straight tracking line by 4" to 10" inches, variation due to design) or an intake grate (which is only designed to load the pump).  Only advanced directional "V" bottom ride plate technology can accomplish this handling function!   Why, first because the ride plate is  always in contact with the water and second because the unique patented "V" on the bottom of this Shred Master ride plate commands directional control of an Ultra in all water conditions.

     You will find as hundreds of riders worldwide already know, once on this Ultra Shred Master ride plate you will immediately know, "Your not firing-off your Ultra rocket without the tail fins anymore"!

    Fundamental Improvement, eliminates all porpoising!  Hull pitch angle is controlled by a very long tail ride plate, which corrects and maintains the hulls pitch plane angle.  The long tail ride plate additionally assists the increasing "V" bottom surface for lift.      

    Fastest holeshot on the market, as proven by many boat lengths, time and time again!  Ballistic speed right from the start, created by a unique lifting patented "V" bottom design.  This allows this the Ultra to accelerate faster, quicker holeshots, and more acceleration speed out of the turns.  On plane in less than 2 feet, and faster out of the turn than in.   

   Imperative Functions, this "V" bottom design eliminates tail sliding and hull drifting turns at all speeds!  In addition, "NO" flat sliding before violent aftermarket sponson catch.  This is accomplished by 3-point triangulated cutting edge!  "V" bottom ride plate design holds the directional line until lean-over sponson catch.  

    Faster Speeds   Due to this ride plates unique lifting effect, created by a transitional increase of the "V" from its front to tail water contact surface.  The increasing "V" down pressure on the water allows the ride plate to a degree, to hydroplane the Ultra hull (ride higher out of the water), in turn this reduction of water contact allows for less water resistance to the hull.  This patented utility of hydrodynamic design in turn produces faster acceleration and faster overall top speeds for the Ultra.       

   Rough Water   This ride plate's hydrodynamic design which allows the hull to ride higher out of the water, bow slightly up, not pulled down, suppressed, and plowing the water like a tug-boat, further allows for less rough water contact to the hull.  In turn a more relaxed ride, no more death grip numb fingers and clamped on bruised inside knees from rough water hull hunting fear.  Just a comfortable cutting edge "V" bottom ride, straight as an arrow as needed in rough water. 

    Testing Conditions   This Ultra ride plate was designed and tested in normal water conditions, (8:00am) to rough afternoon chop.  And produces an overall smooth water 1.3+ mph increase in speed and the rougher the water the faster it will go.  See PWI magazine test below for accredited professional WORLD CLASS PRODUCT evaluation. 

       Note:  Speed test on this ride plate are conducted by advanced recreational to accredited world class championship racers on stock Ultra's to Pro Class 80+ mph race boats, (race boat info is available).  Testing is done "ONLY" in normal water riding conditions.  "ABSOLUTELY NO" 6:00am mirror glass pond testing here!  As we realized 15 years ago, R & D testing must be performed in normal water riding conditions or  whoever's testing claims, will do you no good!
