How much boom clearance will I need to safely use the rack system?
Boom Clearance will depend largely upon the height of the item stored on the rack. The rack, once installed, on average should use about 12 inches of vertical height inclusive of the crossbar. You simply need to add the thickest section of the item to be stored on the rack and add it to the 12 inches. This will determine the overall height required from the deck.
