No, good old American fiberglass. They were built before everyone started making stuff round and Euro.
I like the styling of older boats. There are only a handfull of new builders sticking with tradition. Mostly because it is easier to build a "roundy" boat because you can chopper gun it and pop them out of the mold at high speed.
Rampage is one example. I love the syling of their old boats. The new ones look like everything else. Don't you guys agree.
