The English parts of the website are written according to British English spelling, and on the dry sub domain in both Dutch and British English were appropriate. The translated sections are written in Dutch, German, Italian, French, Polish, Spanish, Arabic, Hebrew, etc.
The EURO currency is used, notated either €3,14 or 3,14 euro.
Temperatures are in degrees Celsius (°C), which serves >98% of the world's population; the Fahrenheit (°F) scale has almost completely been replaced by the Celsius scale, except in the USA.
The date notation is in dd-mm-yyyy since the populations of most countries use this day-month-year format, even if these countries have adopted the international standard ISO 8601 of yyyy-mm-dd.
Month names – like 12 October 2021 – are used in the English sections to avoid misunderstandings.
BCE (Before Common Era / Before Current Era) & CE (Common Era / Current Era) is used and the numbering of years is identical to that used in the BC (Before Christ) & AD (Anno Domini) system.
The system of Common Era does not explicitly make use of religious titles for Jesus, such as Christ and Lord in the BC & AD notation. Therefore, the Common Era notation is a more religiously neutral notation – and not offensive to other religions and atheists – better suited for cross-cultural communication.
The term yachtsperson is used instead of “yachtsman” to include all genders and non-binary sailors, there is however no balanced alternative for “seamanship”.

Must-see or Insight
Worth a detour or Valuable Insight
There is no international preference between the three widely used decimal separators:
- the decimal point “.” in the English speaking world, China, Japan, etc.
- the decimal comma “,” in Europe, Russia, Middle- and South America, Indonesia, etc.
- and in the Arab world the comma-like “٫”
Therefore, both the the comma and the point are used on this website.
Neither the comma thousand separator (1,000,000) or the dot thousand separator (1.000.000) are used, so e.g. for scale of a nautical chart 1:193 000 and for light intensity 120 000 candelas.
Lengths & distances
The metric system is used and therefore metres and kilometres instead of yards, statute miles, inches, fathoms – along with the International System of Units, with three exceptions that are common in the nautical world.
- NM for nautical miles.
- M is used for the range of lights in nautical charts, nautical miles.
- both metres and feet (ft) are used for the length of yachts and catamarans.
Depths and heights are in metres
According to official guidelines, geographical positions should be:
- expressed in degrees, minutes and decimals of a minute,
and not: 24°20'30''N 30°04'20''E (DMS Degrees:Minutes:Seconds)
- without punctuation, and with a single space between the coordinates and no other spaces
- with leading zeros for single number minutes, but not for degrees,
so not: 24°20,500'N 030°04,333'E (with an extra zero emphasizing latitude)
- with the minute tick following the fractional part
- with a decimal separator according to national practice, yet comma is the preferred ISO sign!
51°42,03'N 5°07,14'E 51°42·03'N 5°07·14'E 51°42.03'N 5°07.14'E
On charts and most reference materials you will find:
24°20,500'N 30°04,333'E or
Elsewhere, as on this website, whitespace is added for clarity:
24° 20,500' N 30° 04,333' E or
24° 20.500' N 30° 04.333' E
