We built an 8x10 floating dock using 6 plastic barrels. Because we squeezed 6 barrels in we have some running parallel with the boards and others running perpendicular. The ones running parallel have 1 very "soft" board (from the roughly 35" of no support) and 1 board that pops up a 1/2' or so from the barrel pushing on it. Functionally I think the dock is fine, but the aesthetics are driving me nuts. Any bandaids I could put on the bulging board to bring it down? We used Trex wood if that has any impact.
