"Shaving" a bit off 12ft Replacement Deck Boards

Hi guys...I need to replace some rotted boards on my deck, but the new replacement boards from Lowes/Home Depot are just very slightly wider that the existing boards that I've removed- thus, they will not "drop-in" and must be very slightly edge-trimmed... More like I just need to "shave" 1/16 to 3/32 along the 12ft length of the replacement deck boards edges to get them to drop-in...which tool should I get? thanks
