With the continued absence of a kayaking forum, I'll ask here.

Myself and mates were going to paddle Redhead to Port Stephens in a day tomorrow, but with the continued forecast suggesting a 5 to 6m swell, we thought we would stay off the ocean and paddle the length of Lake Macquarie instead.

Is the southern-most point Chain Valley Bay.
Is the northern-most point Lake Macquarie Park at Cockle Bay at Speers Point?

Can we launch on sand or a boat ramp at the end of Mulloway Rd, off Chain Valley Bay Rd? Same with finish point - is there sand to land on with 'glass boats?
