Bomkicker makes a model specifically for the J/30. The rods are pre-cut to the right length and are sized so the Boomkicker provides the correct resistance. It comes with all of the hardware needed to install it - including the drill and tap.
I ordered mine recently from Mauri Pro Sailing. I paid $230 for the Boomkicker plus $20 for shipping.
