Hmmmm... my understanding was that Canada does require paper charts to be carried on board, regardless of size or commercial status. You folks made me curious to know if I'd simply gotten and been spreading misinformation, though, so I went and looked up what I believe is the relevant legal regulation:
Ch**** and Nautical Publication Regulations, 1995
EDIT: Sailnet is so desperate to sell you charts themselves that they override the hyperlink with their own if you have the word "chart" in the description... thus the asterisks above.
Now, maybe that has been amended somewhere that I didn't find, but the way I read it, you are required to have the most recent version of the relevant charts aboard, unless you have previous local knowledge. That probably does
exempt most Canadian pleasure boaters, but not folks such as Kiata and myself headed north for the first time.
It does not, however, specify that the charts be paper. Go figure. There actually isn't any difference between the paper and electronic versions anymore, Plumper--if you're buying a recent paper chart, they printed it from the same electronic version you might buy directly... says so right in ArgleBargle's CHS FAQ.
Getting back to the original request--Kiata, I overstocked a bit myself and wound up with duplicates of CHS charts 3548 and 3595, which you are welcome to for what they cost me, which was $10 each. I think you're late to the used-chart market in Seattle, though, I scrambled against stiff competition last month to get everything I needed and I doubt many summer-voyagers are looking to sell at this point right as they are setting out!
For that matter, I'm leaving for Vegas in the morning and then setting out on the boat as soon as we get back Monday, so I won't be around to get you the charts, but if you are interested PM me and I can leave them with our housesitter or someone in Seattle you could get them from.
