Dear CK Sailor. You haven't ruffled my feathers at all. What is ruffling my feathers is that Jessica Watson's statements and claims are demeaning to genuine RTW sailors such as Kay Cottee and Jesse Martin and others! Indeed, I like a robust debate, but someone is having a wee tamper with the truth as far as distances go. I've been doing a bit of digging on the internet, and here's what I've unearthed. The attached route charts tell their own story. You will see that Jesse Martin rounded his Antipodal Point. Have a go at working it out for yourself. The WSSR Council lists Jesse's official distance as 21,760 NM, based on a calculated Great Circle distance, as opposed to the distance sailed. My calculation, using my trusty Garmin and a neat little on-line program titled "Great Circle Calculator" (http://216.147.18.102/dist/) (try it for yourself), came out at 21,820 NM but in fact the real distance would be greater than both, due to "meanderings" off course and weather routing. (e.g. the dreaded South Atlantic high), however the WSSRC can only take into account ACTUAL distance, not the distance sailed. The WSSR lists the minimum RTW distance as 21,600 NM, (40,000 Km) the circumference of the earth at the equator. My calculated estimate of Ms Watson's voyage, based on her (questionable and unsubstantiated) data posted on the Internet, is 18,582 NM, which is 3018 NM less than the official RTW distance, and 3178 NM less than Jesse Martin's official WSSRC Performance Certificate distance of 21,760. Further, in the absence of official and independent monitoring and verification, the onus must fall upon Ms Watson and her "people" to prove their claims. (Shades of Donald Crowhurst here) Even though the WSSRC have very recently discontinued the category of "youngest", Ms Watson could have availed herself of the WSSRC's service to verify her course distance, but elected not to do so! Hope this helps.
