Contact Ian at Auswind. He had a demo 2013 14x25 sprint at Merimbula which I'm pretty sure went back over WA after the comp. The 25" was super stable and fast and even picked up bumps really well on a light downwinder (even though that's not what it's for!) I'd love to give the 24" model a go.
To talk to Ian or anybody else about Starboard SUP's you can call (08) 9244 4162 They are situated at the rear of 11 Howe Street Osborne Park. The website is www.standuppaddle.com.au
