I'd take....
1 light rod with snap clip attached for eiter a squid jig or metal slice if the surface fish turn up. Can also clip on a hook to float a bait down or light jig head.
2. Probably another light rod with either a light running sinker or sinker, swivel and trace 1m or so long.
3 medium outfit for trolling or live baiting.
4 heavyer outfit rigged for live baiting or poor mans down rigging.
It doesn't take long to change the rigs anyway. But it's nice to have a squid jig ready for followers and being able to quickly change for bust ups. Btw I have never fished the harbour
