Ok I'm on call and all my friends are on the river so I thought I would work on my boat.. normally I row from a nrs seat bar, but for trips where I need to take more than two passengers I have to take my forward dry box and sit on it.. I am making a seat mount out out of a sheet of 3/4 cdx.. I am going to coat it with behr deckover as I have some left over from my side decks.. I am up to the point of securing it to the top of the dry box... I'm trying to decide between cutting a slit on each end to run a cam strap through or routing a long shallow groove for the cam strap to ride in.. thoughts?
