Very valid questions, I defy you to utter the word wind up here without a swearword accompanying it. i know I do every single time.
This year has been worse than the average over my time up here but not the worst year just yet.
The inner reef offers little protection unless you situate yourself close to the lee side of a reef and it is at or near a low tide, the lower the better.
The problem for our small boats once in the paddock is the amount of flow and the wind direction, there is quite a few kilometres of it to travel through before the opportunity arises to find some calmer water that also see's less fetch.
I used to watch the green island oservations and their graph on seabreese as it gave a good represntation of conditions but they have since mover the GI weather station to the east end of arlington approximatly 45km from trinity inlet and I have yet to get a feel for the conditions it observes.
Anyway no real help I know but suffice to say unless you like banging all the way there, sticking it out in the rough at anchor and then bangin all the way back in a 5m boat never better than 25km/h it's best to wait for a 10-12kn day, these 20kn+ days are simply not worth it IMO.
But yes you can somewhat hide behind oyster/arlington in that shallow-ish area, there are lots of little reef fish that can drive a person crazy in there, but also Spanish and trevors etc + of coarse larger reef fish like trout.
