Recharting of depths is done on a much lessor frequency than other data. Navigation
Aid data is the most commonly changed data. You can find a lot of real world problems with aids that are not on the water
but are on the chart and other mismatches even in most recent data.
If you supplement the charts with updated cruising guides
you may be just fine. cruising guides
add some additional information that you can't get from charts plus the information you may want that no charts have.
No matter what charts you get you need to take them all with a cast of doubt. They can be wrong or at least not the way it really is. You can't know what is wrong because the people making them didn't know either. More recent charts are always more accurate but you never really know what is still inaccurate.
Old charts are always good enough until they casue a problem that could have been avoided with a new chart.
