If I'm reading it right, the maximum wading depth of an L320 is 19" at standard height ( 21" at off-road height), which I think would put the door sill a few inches underwater.

Are RR Sport doors actually watertight? (at least to me, the rubber seal doesn't look any more robust than other cars).... or is it that if you did drive in water at max wading depth more than briefly, or even stopped in such a level of water, then you should expect some water ingress into the cabin?

The key is "wading" depth. You create a proper bow wave and proceed across the stream, river, or deep puddle. The water goes around the vehicle because the vehicle is moving. Yes the lower flap seals and the gaskets will keep the water out.

Now if you misjudge the depth of the water or stop mid crossing then yes water may get into the cabin. If you make sure to keep moving you should have no issues.

We've had the RRS many times in water up to the bottom of the air intake, standing in water...zero leaks. That's well above the door sills...no issues at all. Not a drop of water comes in on the seals.

You can push even more water as Toad says with a bow wave, up to the top of the hood as long as no water gets sucked into the air intake, that's well above the wheels wells...just keep moving and don't stop once moving.

I've gone as deep as close to half way up the doors. Definitely not as high as PJPR01 notes. And yes kept the bow wave going. Water stayed on the outside. Hurray.

i have read somewhere that the doors are designed to keep water out for up to 30 minutes when parked in water - not sure if it is true but the doors do have double seals

I went through the water crossing at the Land Rover experience center in Carmel - definitely above the door sills - and no water came in. On an older model however, you need to worry about things like seal for the wheel bearings - if water gets I there - your bearing will wear quickly and then make noise and need replacing ! That happened to me ...
