However, If you plan on using it in this fashion I would recommend adding a backer plate underneath to sandwich the deck and help support the RAM Style mount.

This is a great way for anglers who have minimal space to have a dual sonar mount on the bow. If you have room for a RAM style mount, now you can have a Dual Stackable mount.
