Newbie - don't understand the design of the seatboxes on our 2006 16' cruiser - toward the bow is open, so if a lot of water goes toward the bow between the seats while fishing, or whatever, it will then enter under the box, and the little weep hole toward the aft is well above the bottom of the deck inside the box, so any water will just sit there. Is there any reason not to seal off the box completely toward the bow?
