Hi
Where did you obtain this business information?

I suggest making amendments to OpenRiverboatMap

Hi
boat=*
My understanding is there is a hierarchy. boat=* includes motorboats & sailboats.
I checked to see if all ways included boat=yes. Are sailboats not permitted on the K&A?
What is the url for OpenRiverboatMap?

It was you who added railway=station to this node
node/3193631672/history

Hi
All railway=station in Britain are mapped. Please don't add duplications.

node/3727609004https://www.openstreetmap.org/node/3193631672

Please don't delete typos - fix them instead.

Hi
All your water=* tags require a natural-water tag in order to render correctly.

Tip:

Instead of deleting a current object, only to replaces it, could you use the existing way, in this case a platform, to create the new object. It retains the history of that way which is useful for validation purposes.

As you're aware there is already a railway=station node.
node/6291570884
There can only be on tag for a station.

Hi
Where did you get details of this path from?
I don't remember there being a gate in the fence.

Yes, one railway=station tag per station but may have multiple building=train_station buildings.

Please refrain from duplicating railway stations, especially as you're aware there is an existing.

Hi
I think these are more accurately described as chokers not chicanes.

Hi
Where did you obtain the maxpeed info for this road?
way/24528007

Hi
please don't change Wikipedia (or other) tags to pages that don't exsit.

node/6677241028#map=19/51.386551/0.549834

Have a look at this:

Plus a few youtube videos

Hi
I think you've deleted the more accurate of the duplicating platforms.
At Chancery Lane station they're straight, adjacent to the rail tracks & don't cross over them.

Hi
As mentioned on previous occasions, these are not railway stations. All stations are already mapped.

Or you could have left it alone as it was performed with knowledge.
