I discovered today that I have no clue in the sea (even walking the rig
out to waist deep). My rig (and the sea) is way beyond my skill.
I am going to have to go back to basics and do a beginner course again.
I was wondering if anyone can recommend a school/instructor ?

There was a guy on a 92L board at Semaphor South who gave me some down
to earth advice. If you're reading, Thanks :)

Ja

Ahh don't you hate it when you have to start again!!!

Minor set back :)

If your trying to get back into it try down at the wall in a northerly,

Where is the wall ?

Good luck mate remember practise makes perfect.

Thanks :). See you on the water (eventually)

Sorry mate the wall is down near port adelaide, if you look up the crusing yacht club of South Australia on a road map youll see a long break water just north of it on the end of the Port River. You sail on the southern side of this in a northerly for some nice flat water conditions.
