You blokes just love to make your lives complicated dont you

I suppose the reason I didnt put nappy rushplans on the site was that I want other , more experienced builders to start thinking for themselves.
Which they have obviously done
However, when I tested and tuned NR on lefroy, I was suprised to find that it was no faster or slower than a standard, basic mini or even ankel bijter. The results were very similar on the beach at Yepoon.
the only place where it really got up and mangled the opposition is on the slippery , gravelly and rutted surface of Safety bay.
On a similar vien , I trialled skiny 20 and 16 " wheels on the gypsum surface of Lake Gillies and they were decidedly slower there.
On a good sailing surface the faster yacht will be the one with a well cut sail matched to a good mast, sailed by somebody with their brain in thinking mode.
For our upcoming GPS speed trials we have begun to recognise material and construction differences, along similar lines to the blokarts , in the "classes" of yachts we will be considering.
I suspect time will sort out a final formula.
We still havent seen any 'V'frames or decent full body with wooden axle yachts yet to get a really good comparisons
