How to chop the tail off my 9'0" Thrusta' and make it a Quad?

Hi denizens…

I have a 9’0" x 19 1/2 x 2 3/4.

It sinks side to side when I paddle like a madman. One time I fell off paddling. It works @ The Bay >12 foot, but 10-12 foot Sunset its too hard catch em.

Board is solid, 3/8 or 1/2 stringer; Clark foam blank; glassed with epoxy.

I want to chop the tail off about 6-8" and make it a quad. I think chopping off the tail will make it more stable.

Board is long and pulled in, doing this will make it more stable, i reckon.( i’m 6’4")

Please help a brotha on how should to set the new fins etc.


I say don’t do it.

  1. Rocker will be absent in the back of the shortened board.

  2. It’s gonna be pretty thick.

  3. Why waste a 9’ thruster to make… what?

  4. Used boards are a dime a dozen, especially used shortboards. Get one.

  5. Rails will be wrong on the short result, and by the time you could reshape them, might as well buy a used shorty.


  1. Short and thick does the trick, but long and thin goes right in.

10-12 foot Sunset isn’t my idea of a place to be experimenting with no tail rocker. Why not sell the train wreck and get a board that works. Like my redneck daddy always said, “you can’t make a silk purse out of a sows ear”.
