The other threads that I have read here lead me to believe that the Arch is pretty much hollow. I want to make sure that the launchers will be as solid as possible. Any photos of complete projects or how you installed them? This is a photo of our boat. Thanks.
Also anyone that is selling launchers that may fit, please reach out.
I have seen rocket launchers that actually clamp to the grab handles on the side of the arch. That appears to me where they are mounted in the picture you posted. By the way the arch is hollow. Made of approximately 3/16" aluminum. I vote for the clamp on version, I hate putting holes in my boat. LOL. Good luck Tom
