I went out for a spirited drive today in the sunshine.... At least four times the front suspension bottomed out on depressions on the road (not potholes as I try to avoid them if I can).
The feeling is akin to driving up a kerb with a flat tyre.
Is any damage being done when the suspension 'bonks' like this?
The rear very rarely bottoms.

How old is the car and how many miles has it done, maybe you have a shock absorber issue?

Check for evidence of possible tyre contact with the bodywork. I noticed that it has been happening on my car. Don.

My bet is the diff hitting the parcel tray -- was cured on my 2009 Plus4 by swapping the factory shocks for Rutherford AVO versions.

The diff hitting the tool tray certainly makes a bang! But I've also had an occasional bang from the front, which I've put down to the exhaust catching the chassis. Clearance is very tight and a bit of chassis twist would be enough. The stub axles have a rubber buffer at the top, so not possible to bang, even on full deflection. On overrider cars though, the track rods could touch the bracket (they pass through a hole in the bracket).

It's the front suspension rather than the rear.... and I will check for tyre contact.
Will it cause damage to be bottoming at the front?

Soft springs heavy engine. I guess Morgan have tried to improve the ride. Avo's from Mulfab help a lot, but add a heaver spring really stops the banging... But the compromise is a stiffer ride. You can almost stop it with Avo's but the they are not set correctly that's why you need both springs and Shocks (set hard they do not extend fast from compression)

Perhaps you need PJB and Suplex's new rising rate front suspension!!
