Hi Anthony
I've done part/all of the Moffats-Mooloolaba / Mooloolaba-Moffats a number of times, just have to wait for the right conditions

and when I get to be in Caloundra with my family.
I've been using a 14ft board similar to the one Sue is selling, which works very well on that run, except for getting through close-out shore-pound and strong cross-shores.
There is a listing of SC SUP people which I can PM you about.
I'll let you know next time I do a run. A lot of the SC paddlers will be at the Noosa Festival race on Sunday PM.
