Not at all. I am just using the gladstone multi fleet as an exemplar of the australian multi fleet. It is not like we have a fleet of orma 60s in oz. You get one 60 a few dayboats (raiders and the like) and after that a heap of 40 to 50 foot cruisers which are the bulk of the fleet unless we are talking about taking some farrier trailer tri south.
I am not actually. check out the elapsed times for the gladstone sometime where the multis sail a faster course by a few hours. Even in perfect multi condition most elapsed times are not better than the farr 40 od in a race with no upwind.
