Thanks Alan and StinkyPete.
I wouldn't deliberately set out in an uncomfortable chop although the boat (Haines Signature 600F) is very seaworthy. A smaller Signature with a similar hull completed an epic journey.
"Signature's classic 542F hull is an old Aussie favourite that's been around long enough to be considered a tried and true, proven performer. She's based on the Haines Signature 540F hull, which comprehensively proved its sea keeping abilities during Hans Tholstrup's solo journey from Australia to Japan a few years back. The trip gave this Haines Signature hull an undeniable pedigree."
I also want to have a go at the King George whiting (unsure where or when they bite) and snapper off Whyalla.
