The problem was even though I had down loaded all the O-Charts for the area I was interested in and I also did the "Prepare all ENC Charts" etc function and rebuilt the date base more than once etc. If one area's chart showed up, another blanked out. I could never get a continuous knitted visualization of the North Channel of Lake Huron at any zoom level. This made it difficult to chart routes etc.
This had never been the behavior of the NOAA ENC charts on Open CPN at all. With NOAA ENC charts I was always able to obtain continuous visualizations of areas I was interested in. Besides that, the detail level of the O-Charts is unsatisfactory. Both NOAA and Navionics charts are worlds better. I would not recommend O-Charts.
