The 23 and 28 is being laid up and owned by West Coast Tooling and they've done alot of lay ups for a bunch of MFG. WPM, Cole, CA Performance, Water Rod and more. They used to be tied to Shockwave, so most of the Shockwaves made before 2002 were done by West Coast Tooling. They are also laying up a 19' Cat for Tom Papp right now. I'm pretty sure WPM isn't rigging boats anymore and the 23 and 28 are being rigged at Aftershck.
