There is a posting somewhere from Robin about this in which he explains that he didn't sail for Hawaii and has given up the idea in his present boat. He is now looking at buying a bigger steel boat to make the voyage. I think that he may have found the trip a little too daunting in his present boat.
Its a pity that all that preparation has gone to waste but no doubt he will be able to employ what he has learned when he has the boat in which he has more confidence.
Robin, if you are out there lots of us want to know how you getting along with your plans
