Ram Mount - Ball mount for Portable GPS

[mo2vation]

Hi all.

I'm gonna mount my Garmin GPS onto my Prowler 15 using the Ram Mount system. I want to put it on the rise between the footwells. I transport the boat upside-down on my Land Cruiser (see my Av) so I'll mount the ball low enough to still be able to do that without putting the ball mount through my sun roof!

When mounting this, would you recommend Rivets, Well Nuts or small SS bolts with washers and lock nuts?

My thinking is this:

• Well Nuts only grip the inside edge of the hole, and although they are removable, that's a feature I won't need for the ball mount

• Rivets grab a larger section of the hull beneath the holes, so they're likely a bit stronger

• Small SS bolts with washers and lock nuts are strongest, and seeing as I can likely reach the back of this rise from the front hatch, why not use this method?

A copious slathering of Goop will be applied to the fastener at the time of the install.

Your thoughts are appreciated.

Thanks
