My family is going to Charleston, SC here in a few weeks and we are thinking about going off shore fishing. The charter we are looking at offers a trip that last about 9 hours and goes 30-50 miles off shore on a 27' center console boat. Some of the family is worried about sea sickness. Is it as common as we all think or is it something we really shouldn't worry about with or without some Dramanine? We all have been out on speed boats on lakes in Indiana and Michigan but never out on the ocean. The charter said they will not go out if the swells are over 5'.
