i used to hit long reef in a 4.1m Alf Stessl with a 30hp on the back, obviously the days had to be picked but shouldnt be a problem @ all...
As for squid...... they really are EVERYWHERE!!!..... just find shallow areas, rocky,kelp or grassy areas are all sure things, a good place to start would be quarrintine bay. Saying that i used to think that there was "Secret" squid spots, but i have caught them everywhere, Balmoral is another popular spot. Obviously every1 has their little spot X that performs well and every now and then the surprise by catch, i caught 2 squid on Fri 50cm+ whilst fishing for kings.....silly creatures.
Good luck with the snapper, let us know how you go.
