Sydney-Hobart briefing (update)

David Griffin

24 December, 2017

Little has changed since our original briefing, so here it is again just lightly edited: We have an interesting situation this year, with an unusually strong, cyclonic (clockwise rotating, cold-core) eddy off north east Tasmania. This is quite likely to persist until race time, in which case yachts sailing through its western side (presently on the rhumbline) may encounter adverse currents of 1kt. If winds are light, this could be an important consideration. Conversely, favourable currents may be found on the eastern side of the eddy – but that would require quite an extensive detour off the rhumbline. It might be possible to avoid the adverse current by sailing very close to land but that is difficult to assess. [more]
