I think Chichester found that Gypsy Moth IV was not nearly as good a boat as hoped but he still managed to make it around the world. I think he stopped in Australia to get work done on the boat so he could finish the trip.But do I agree with the ratios? No, not really. A good sailor can make a bad boat work but a bad sailor can't necessarily make a good boat work. I reckon the ratios are reversed.
