Raster charts are going away because it is too expensive to keep them up to date. The chart has to be redrawn every time something changes, on a ENC chart only a few data points have to be edited. Charts can be updated and distributed more frequently. CFR 15 Subchapter F requires NOAA to release new charts within 5 days of changing them. Can't do that with Raster Charts.If I'm reading this correctly, the commercial charts named above, that are based on Raster Charts will no longer be "Official"?
Frankly, for our purposes I wouldn't worry about this at all. If you boat in an area that is subject to frequent shoaling, then by all means get the most up to date charts available. If you're cruising in unfamiliar waters, be sure to have the most up to date charts, which may not be on the chip you just boat from West Marine, update the charts as soon as possible. However, there is no legal requirement for recreational boats to carry charts. However, legal requirements and good practice are not equivalent.
