I was just throwing this question out to get some opinions on what the best way to mount my fishfinder swivel bracket onto my fiberglass boat. I am putting it kinda next to the concil more in front of where my grab rail on the side is. I just do not want to mess it up drilling through. I have heard put tape down first and drill slow. Also to mount my gps i heard in another posting I had to velcro it so I do not have to drill holes for it.
