I agree, there is shoestring, and then there is SHOESTRING...That is quite remarkable with only boat older I think Pip Hare's???
You get to the stage of having to come up with categories of "shoestring"
Like "new boats" pretty good budgets there is still the 'poor'. Such as Tripon (a 1st timer) and Ruyant as Miff points out who struggled financially and were touch and to get to start line at some point.
Benjamin explained in his last interview that it is because of the arrival of a last minute sponsor (OMIA) in September that he was able to by SOME new sails (so I assume that some of his sails are still not new for this race). He also explained that the new sails really changed the performance of the boat, and he is still learning how and when to hold back, and when to be on the attack.
I would assume that Armel Tripon and Thomas Ruyant have all new sails for the Vendée Globe.
