Make the Ocean Rough

Be close to the water when you do this, like on the deck of a launch or in a canoe etc. You can do this spell in your mind, but it also works saying/whispering it. If you are on a boat and dont know the captains name, just do captain. I command that the sea is harsh and difficult, to make it hard for (captain boat/launch or youcanoe/kayak) to get through. This is my wish, So mote it be.
