Bob, The chartpack you want is 14786. It's a NOAA chartpack of the entire NYS Canal System. The Champlain Canal and Lake Champlain are 14786-20 through 14786-26. Lake Champlain is 14784. These are the raster charts. I doubt there are vector charts for that area yet. I would ass/u/me that would be a very low priority in these fiscal times. After that, it's the Canadian fee chartpacks. The NOAA RNC charts are available. I have 'em. I probably got 'em from Maptech's website. Don't know if that's still alive, but you should be able to get 'em from NOAA's site. Or perhaps, from Roespoint's site. Jim Peg and Jim Healy aboard Sanctuary Currently at Charlotte Harbor, Punta Gorda, FL Monk 36 Hull #132 MMSI #367042570 AGLCA #3767 MTOA #3436
