Dimples on boat bottoms? Why? Originally, golf balls were smooth. But golfers noticed that older balls beat up with nicks, bumps, and had slices in the cover would fly farther. Thus dimples were born. Like you see on golf balls, dimples equal less drag, provide lift, and create a more stable flight. On the bottom of your PAVATI™ drift boat the dimples create bubbles that add lift but the biggest benefit is the ease to break away from the drag of moving water. A real advantage when you’re stopping your boat to fish. The turbulence created by the bubbles actually cuts the power it takes you to break away from the rivers grasping current. Here's why. Like a power boat, when your prop gets air around it, it cavitates. Your prop breaks away from the water and spins freely. PAVATI's dimples create air bubbles which break the bottom away from the water the same way! You can actually hear the bubbles under the boat when you stop. You may have an opportunity to fish that riffle you would normally be blasted by, plus it’s easier to stay there. It makes sense. Chuck got this idea from Sail boat manufactures who have been using this technology for years. They are also using this same technology on snow boards and airplanes. Sail boats are claiming 8% less drag.

Stronger - Quieter - Easier PAVATI also uses an optional sprayed on polymer with “Kevlar®” on our bottoms. This is a coating we found being used in rock quarries to protect dump truck beds from the harsh impact of loading shale all day. On a drift boat, it not only adds strength, it's very smooth which equals - slippery - as it slides over rocks with ease. Uncoated aluminum bottoms will actually hang up on rocks, a potential problem in fast moving river currents, An added bonus, the “Kevlar®” coating deadens the metal sound aluminum drifts are known for. Also offered is a UHMW (ultra-high-molecular-weight) polyethylene sheet glued to the bottom of the boat. UHMW has the highest impact strength of any thermoplastic presently made. Among it's many characteristics, it has a very low coefficient of friction, is self-lubricating, and is highly resistant to abrasion (15 times more resistant to abrasion than carbon steel). Its coefficient of friction is significantly lower than that of nylon, and is comparable to that of Teflon, but UHMW has better abrasion resistance than Teflon. It is odorless, tasteless, and nontoxic. UHMW works great for sliding over rocks and deadens the metal sound as well. Your fishing streams may not be as rough and not require any type of extra protection coatings. You can just leave it bare aluminum, painted with automotive paint, or powder-coat finish. With the Kevlar coating or the UHMW on your PAVATI drift boat, you will instantly notice the quietness of a wooden boat. One of the biggest complaints of metal boats. Our hull design will give you more control when in the currents. They ride higher in the water so swirling river currents go under you. And, easier stopping in river currents. A big plus when trying to stop mid-stream to fish your favorite spot. Pavati Marine is changing the way you row a drift boat so you can catch more fish, stay on the river longer, safer, and look good while you’re there. |
