<div>I’m looking at the boatyard right now. Most of the boats are on land that is dry at low tide. There are some additional boats and at least one of the mapped ones has gone.</div>

<div>It is (or was) used as a workshop or something similar, I think. It might have been moved occasionally, but that was definitely its usual mooring (might still be, I haven't been that way in a while). </div>

<div dir="auto">The banks on that part of the channel are shingle (and can be walked on in places, if you can find a way down). I don't see why that would matter to industrial usage, though. <br>

<div>However, this is a working boatyard (or at least was recently), so these boats (not ships) are unlikely to be permanently moored. I'd have thought the tidal range on the back channel would make it a most unattractive location for a houseboat or similar.</div>
<div><br>
</div>
<div>When I worked a little way downstream (Europa House) I mainly recall muddy banks and next to no boats being regularly moored.

<div dir="ltr">The building is tagged layer=1, indicating that the side stream flows underneath it. (The river doesn't have a layer tag, but layer=0 is implicit). This is indeed what happens; at low tide the stream is no more than a trickle and the boat is
very firmly atop it.<br>

<div>And rivers flowing through (not under) buildings is an entirely valid occurrence also; this happens at every mill-house, for a start.</div>

At this way, the River Thames is apparently flowing through a commercial <br>
building, which might give any renderer a headache:<br>

If it really is a building, the river way should go round it.<br>
