Maybe in 20 years it will be a good post
For sure, the availability of CATZOC charts, ones adhering to the ZOC system, depends on the jurisdiction(s) in which you sail.
Starting around 2014, all new Australia
large scale charts are CATZOC. Electronic and paper nav charts. Small scale PNCs are not all CATZOC.
is not the richest economy on the planet - it usually stands anywhere between No. 13 and No. 20 in rank order by the size of the economy. If Aus can afford to move to CATZOC, there are a few other economies that have the capacity to move to CATZOC.
I cannot speak for the entire set of UKHO charts - one of the largest coverages in the world - but I believe some large proportion of paper and electronic nav charts are now CATZOC.
UKHO has a better version of an explanation of ZOC than what I wrote, at: https://www.admiralty.co.uk/Admiralt...OC%20Table.pdf
Australians all can download the Mariner's handbook for Aus waters
, with much the same explanation of CATZOC, for free. See: https://www.hydro.gov.au/prodserv/pu..._Edition_5.pdf
Of course in Aus, chartlets made with planing hull
runabouts in mind such as the QLD Beacon to Beacon series of charts for recreational boaters are not yet CATZOC. The taxpayers who pay for the hydrography and cartography will soon or late demand that that those charts are certified to ZOC standards.
I've not sailed in US water for 2 decades. My understanding is that NOAA started introducing ZOC for selected charts in about 5 years ago, 2016. So YMMV.
One message is to regard all non-CATZOC charts as ZOC C or ZOC D (or worse) and to follow the recommended UKC allowance for those charts.
and PNC are just like other goods you buy. Even in Third World economies, packaged food
comes with nutritional info that is certified; in developed economies urban residential houses are built to standards; and even generic pharmaceuticals made in India
are tested, approved, and certified.
