Doing my research having recently booked for October half term, so a couple of weeks after this thread is referring to. Passage North South more of an issue due to daylight particularly getting back later in week. However with a boat with 6’10” height, what is the issue with going nearer to high water. OK its going to be slow for a bit, might feel a bit scary (Although I don’t know how fast the stream runs) and if the weather was bad the wind against tide might be an issue. What am I missing, if you read anything it is like you will die if you get the times wrong. Although it doesn’t help me, why not aim for high water slack to get through Yarmouth if you are less than 7 feet.
