We looked around for electronic maps which will work in our Furuno NavNet VX2 chartplotter. This was quite frustrating in finding a supplier who we were happy with. Some suppliers readily gave answers but shocked the crap out of us with their prices. Other suppliers offered good prices but their service is absolutely shocking - some never even responded to our inquiries. In a depressed economy, one would think that suppliers would be keen chasing and closing extra business - clearly not!
Then we found Bellingham Chart Printers.
We dealt with Megan who delivered excellent service, promptly answered all our questions and gave us a great price for the electronic charts we were interested in. We ordered the C-Map Mega Wide charts for South America, Atlantic Coast Mexico and Caribbean, Australia New Zealand and Papua New Guinea Solomon Islands. We already have the Mega Wide charts for Africa and we will later expand our chart inventory to include Japan, South China Seas, Thailand and the Indian Ocean.
You also want to check out the Chart Portfolios offered by Bellingham Chart Printers. These papers charts are available in various sizes, in bundles which are printed in black and white (or rather grey scale) on durable paper. These charts bundles really sell at excellent prices. If your navigation and charting system is electronic, these chart bundles will do an excellent job as a backup chart system.
