Finding it won't make any difference to boat speed, surely?  You can only
augment boat speed if you can find a way of exploiting lift to a greater
extent than already achieved, and this will only be an advantage if nobody
else does it... so if it is at all possible, it is unlikely to be discussed
here or anywhere else, just demonstrated at the most important race.
