Hey Toby,
I do my dawn raids from north of the river, rigging at Dalkeith and then sailing across to Pt Walter. It works well in any westerly type of direction, and puts a smile on your face for the rest of the day

If you're south of the river and launch at Pt Walter then you'll find me, otherwise it's a long way away.
Definitely looks like something might be happening this week, I was even half tempted this morning based on the forecast!
