Rideplates, rounded, concave, radiused. ribbed, dimppled and slotted proved to do nothing significant in a drag race set up. The rule of thumb when we started racing was somewhere around 18 inches. Well being young and fearless Jeff ,Norm, and myself decided to test ridplate length with one of the Dash for Cash boats at one of our famous test scessions at the now Blue Watwer Casino formly BlueWater home of the NJBA. On an off weekend we took our test to the water and this is what we came up with .Starting with a 18'' we ran the boat everything went well our std setup Test 2 20'' ran the boat and it was visibly freeer on the water all settings remainded the same.Test 3 22'' rideplate boat got way to loose. Test stopped on length. Now we went short rideplates 16'' was tried and the difference was the tail was stuck so we got the bright idea to try no ridplate at all and this is where the fun begins. The boat accelerates good, gets to top speed OK but the shut down was pretty bad, boat came down extremely hard .That was basically the end of the test secession on rideplates. We felt that we could make the boat a little better in different water conditions with the aid of a different length rideplate. Not a good idea to run a boat without a rideplate. So all you guys makes sure you have the proper length, bolts to hold your underwater hardware on because you'd never want a rideplate to fall off!!!!
