No, sorry - the BSB
plug-in is using a Windows-only 3rd party SDK.
With respect to the cost of vector charts: the chart suppliers are aware that their pricing is not suited for the recreational user. We are just not their target audience.
But in this moment they have no solution.
And yes, the Canadian charts are from the most expensive group.
For the Canadian NW I counted about 4 general charts, 20 coastal, 95 approach and 110 harbour maps, total aprox. 230 cells. If you calculate with a price
of 10$ per cell they even gave a discount.
Time will show.....
