I doubt it. Last time I was there, they were pretty new

Here's a shot for George showing the Jetty locations in the RN Dockyard so if I mention one, he knows where I'm talking about

The only one I'm not sure of is North Corner Jetty but I think it's right. It's either there or off the LH side of Fountain Lake
No.1 Basin hasn't been used properly for years and was left pretty much tidal.. a few plastic minehunters in there as shown in his latest screenshot (good guess George). No.2 Basin likewise but non-tidal (generally.. it's tidal in that shot). No.3 Basin is a long term resting place and non-tidal. Main access to the dry docks so a ship would move from tidal to 3 basin and from 3 basin into DD (unless it was one of the bigger DD's closest to the harbour). Out of DD to 3 basin and from 3 basin to the harbour when ready. Rumour has it there's a train in the bottom of 3 basin.. blown there by a German bomb in WWII. Dunno how true it is though.
So.. Fountain Lake.. Destroyers and Frigates, North Corner - the same, Middle Slip to Pitch House - Frigates/Destroyers/Cruisers/Carriers and finally, South Railway.. Destroyers/Frigates

EDIT: On reflection, I think the unlisted jetty to the NW of Fountain Lake is or was North West Wall
