I would love to see some of the A Cat guys build an arched front beam with no dolphin striker. Are there any out there already?

It would have to be made of carbon of course, unless you're really good at custom bending alum. tubes.

I guess you could put on a huge oversized straight tube, either alum. or carbon, with a thick enough wall, it wouldn't need a striker for support, but it'd be heavier and more drag when you do hit the top of a wave with the beam.
