Because of the late start to the season for us and going on several trips this is the first time we have gone out of the River Deben in Suffolk UK and seen for our selves the new channel/entrance to the River. It is very different this year (2023) than previous years. All I can say is follow the bouys carefully and keep to 2 hours ish either side of high water.
