Sea Chart Corrections & Updates: Update and correction of paper sea charts?

Sport skippers should always have up-to-date nautical charts on board. In addition to electronic charts, these do not always have to be new (paper) charts; it may also be worthwhile to correct older material. This also applies to Croatian waters. SeaHelp explains what should be paid attention to.

Paper nautical charts represent (in addition to the now widespread electronic nautical charts) in a particular sea area, among other things, its sea routes, coastlines, navigation marks, depths, danger spots and restricted areas to enable safe navigation and planning for shipping.

For Germany, the situation is straightforward: the Federal Maritime and Hydrographic Agency (BSH) produces paper nautical charts for the area covered by the Seeschifffahrtsstraßen-Ordnung (SeeSchStrO). This includes rivers, the territorial sea as well as the German exclusive economic zone, including the partly adjacent areas of neighboring countries.

In Germany, there will soon only be international nautical charts in DIN-A0 format and national charts in DIN-A1 format

Currently, the German nautical chart system is in a conversion phase. The original 66 large-format paper nautical charts of the German sea area with the respective plan charts and the remaining seven series of small and recreational nautical charts for the German and Polish Baltic Sea coast are gradually being withdrawn. They will be replaced by international nautical charts (INT charts) in DIN-A0 format and by national charts in DIN-A1 format.

The future national chart series will cover the entire coastal area of the German North Sea and Baltic Sea with approximately 100 chart sheets when the new mapping is completed. The charts are available in standardized scales: 1: 12,500 (except 1: 3,000 and 1: 6,000) for port charts, 1: 30,000 or 1: 50,000 for approaches, 1: 150,000 as coastal charts and 1: 375,000 for the coastal overview.

The BSH nautical chart series is part of the worldwide IHO standard and has double numbering

The BSH international nautical chart series is part of the worldwide IHO nautical chart portfolio and features dual numbering. This consists of chart number and INT number. The chart number (see Nautical Product Catalog) is assigned by the BSH. The INT number is assigned by the IHO and is derived from the region and scale range. Both chart numbers are printed on the nautical charts.

All paper nautical charts of the BSH are structured according to the international charting standard Chart 1 / INT 1. It is an integral part of the standard S-4 (Regulations of the IHO for international (INT) charts and chart specifications of the IHO). Official nautical charts must conform to certain recognized standards to ensure safe navigation in shipping and to meet legal requirements.

Nautical charts must always be kept up to date – through new purchases or corrections

To this end, recreational skippers must always use the latest editions of nautical charts and sea books, continuously correcting them and thus keeping them up to date. All changes that have occurred after the publication of a nautical chart or a sea book can be found (for Germany and adjacent waters) in the Nachrichten für Seefahrer (NfS). They contain corrections and reports on measures and events of larger scale or supraregional importance.

The NfS correct the latest editions of the official German nautical charts and nautical books listed in the Catalog of Nautical Charts and Books. They also contain notices and regulations issued by authorities, insofar as they are of importance to ship navigation or are required by law. The NfS are published weekly in both printed and digital form.

Also in Croatian waters, in addition to certain documents, nautical literature appropriate to the sea area must be carried

So far, so good. But how does it behave during a cruise through Croatian waters? First of all, certain documents must be carried on a cruise through Croatia. These include proof of fees paid in Croatia (cruise tax, permit) and a valid boat registration also a liability insurance certificate.

Furthermore, a proof of ownership or certified power of attorney, a boat license, the passport or ID card and, if applicable, proof of paid sales tax (T2L paper or original invoice) can be shown.

Finally, appropriate nautical literature suitable for the sea area should also be carried. In addition to port manuals and an Adriatic nautical guide, this includes, first and foremost, up-to-date charts. These are available either in electronic form – or as paper charts (note: the paper charts are the “official” charts, not the digital charts!).

Official Croatian charts are published by the HHI; these can also be corrected by yourself

Note that the sport boat charts for Croatia published in Germany e.g. by Delius-Klasing (Adria I + II, 3 Übersegler and 25 Revierkarten, new as of March 2023, available e.g. from DK direkt or Hanse Nautic) are not considered “official” nautical charts; the “official” Croatian charts of the HHI (Hrvatski Hidrografski Institut) are available e.g. from Freytag & Berndt (Croatia total, 29 charts).

But what if you already have Croatian maps, e.g. from your last vacation or the one before last? Can these be corrected just like their German counterparts? The answer is yes – if you know how!

Although until a few years ago there was an overview map with the annually new Croatia vignette (No. 101, can currently be purchased in nautical stores), this should not be used for navigation. Rather, the official Croatian nautical charts should be used. If you want, supplement older charts as follows:

All info on rectification of Croatian (paper) nautical charts is available on the Internet at hhi.hr

First open the official website. In the menu first select the item “e-Services”, then the sub-item “Notice to Mariner (NTM)”. Now a table opens, you go back to the creation date of your respective paper chart (date is noted on each chart) and perform the “Male Korrekture” yourself.

To do this, open the respective PDF (available in English and Croatian), and change or add to the respective document according to the instructions of the HHI. After the correction, the keyword “Male Korrekture” as well as the date and the signature of the corrector should be noted on the respective card.

New edition available soon: the “Beständig”, a standard work of nautical literature for Croatia

In January 2023, the new edition of the popular standard work 888 ports and bays – Croatia, Montenegro and Slovenia with 760 plans and 46 maps.

While this is a reliable reference book that explains local conditions, it should be expressly noted that the “Beständig”, as this nautical guide is also fondly called, does not replace nautical chart books.
