Re: Nova Scotia currents
We have gone up the east coast of NS from Chester to Bras d'Or Lakes and never noticed any significant currents to worry about except at the northern end of Bras d'Or where the current is very significant indeed, but current info is readily available at Baddeck.
In South Africa doing lots of boat stuff. Departure north from Cape Town around December 15th. Arrival in the Caribbean around the beginning of February, after 5300 miles or so.
