Southports beach is very unusual, what can be considered beach is very narrow, a meter or two from the sea wall at most - further than that all becomes mud rather than loose sand, shells and stones.

You can walk under the pier when the tide is low however as mentioned earlier, it is not loose sand so from my understanding would be mapped as  wetland=tidalflat as it appears to be to the northeast of it. To the southwest of the pier the beach stretches little further out from the sea wall, far enough for a small section to be dedicated to car parking however it too quickly becomes a tidalflat as you go further out.

I plan on visiting soon so hopefully will be able to get precise details on where the boundaries should be set.

I am new to OSM and still learning the ropes, reading through the documentation and so on, apologies if this information is not useful or contributively to the project.
