Paddling around Calshot Spit at low tide requires you to stay a long way offshore due to the gravel banks which extend up to 400m or so out in two directions (look closely at this google map and you can just make them out). This can put you close to the edge of the busy shipping lane. In daylight it’s an easy prospect however paddling at night it can be quite tricky.
Over time, I’ve worked out a set of handrail features made up of various lights/landmarks which I aim for or use as the markers to keep me far enough out to sea but away from the shipping channel.
Occasionally however I get caught out by a particularly low tide and run aground. Thankfully I can simply push off and head further out to get around the obstacle or in the worse case scenario jump out and wade the boat out unlike these poor folk just off the Isle of Skye!
