Hard luck on the knee Dan.. I have done ligaments before, ecruciate.. replaced. Now have dodgy hip which governs which side I get in kayak and dismount from. You will be fine and where there is will there is a way. Once your seated in yak you shouldn't need your knee.
Fishing off bays was prety tame this arvo.. disappointing really, which I put down to water quality... very green and too much sediment. Few smaller fish (snapper) there but none over 35 cm today (weird cause were few better ones the other day) so all caught today went back. Baits used today mix of half yellowtail, kahawai cubes and flounder heads and still couldn't buy a decent run. Kahawai werent't working either... jet skis in abundance though
