Not sure where Coffin Bay is, so don't know what your approach will be. We've spent a lot of time in Eden waiting for decent conditions for crossing the Straits, and have found that things usually start getting better around early January. We try to leave as the center of a high cell crosses the coast. Usually get enough light wind
turning N'ly to reach shelter before the next frontal passage
arrives... usually at least to Wine Glass, often to Spring Bay or Mariah Island.
The West coast
has few hidey holes. If south bound, Macquarie Harbour and Port Davey are your. only real choices, and getting into Macquarie is difficult in big winds. Local fishermen have some places they run to in harsh weather
, but they are far braver than I am. Don't always make it, either...
Having said that, the run up the Gordon River out of Macquarie isn't to be missed, and Port Davey is just spectacular. We keep going back!
All in all, Tassie is one of our all time favorite cruising grounds... in their so called summer! By April single
digit temperatures drive us northward towards the sun. For us, cold and cruising do not combine well!
