Keep it flat. No side sanding or digging with it.
You will have a temtation to use it to sand the primer. If you want a stright boat, don't do it. Hand block it with a rubber block. It will take you about 2 1/2 to 3 day's to do it right.[just the hand blocking of the side's and transom]
PS I don't work for beer anymore. Those day's have long past. Show me the money. $
