    I broke my rideplate extension today



    I was out on the bayou all day today and ran 77 mph, but had a bit of porpoising. I guess saving 12 pounds off the front by going with the RXX hood made enough difference to make me porpoise.

    So i thought, "no big deal, i'll just bend my rideplate extension down a little bit" I only bent it down a hair and launched it for a speed run. What shocked me most is i LOST 2 mph
    So i went straight back to the landing and tried bending the extension back up and the damn weld cracked

    Now that i give it more thought im wondering if i should just keep it off alltogether and come up with another means of reducing porpoising.
    If bending the extension just a hair scrubbed 2 MPH i wonder how much speed i was losing by just having the extension in place

    I doubt you were loosing any speed with the extension running true to the hull. By bending it down you just put a "hook" in the hull right at the transom, the place where hook will cause the most drag and bring the nose down. I have never seen trim tabs slow a boat down unless they were in the "down" position. Even a couple of degrees make a big difference.

    Why don't you try a set of lever contolled trim tabs?

    Jerry I noticed on one of the pic's from WF one of the RXP's had about a 3" extension about 6" wide in the centre of the ride plate didn't go all the accross like yours, I wonder if this would work better

    Well i cut the rideplate extension completely off tonight.

    I have another idea. Broke out the grinder and started grinding into the fiberglass

    Going to go with some trim tabs like Burnwater had on his RXP (pictured) but wanted to make a straight base for the tabs to mount on.

    I will make my tabs with slotted bolt holes that way i can move the tabs up and down to find the sweet spot, but what i would really like to do is make the tabs on a hinge and have some sort of turn buckle type adjustment on them. That will take a bit more thought and engineering though.

    Hopefully it all works out alright

    I am pretty sure someone out there makes a finger lever controlled watercraft trim tab. If you can find out who it might save you some time.
