This post is about generalizations. I know there are (a few) exceptions on these generalizations (you and me), so no offense. Being a Dutch skipper myself, let's start with the Dutch.

Unfortunately the
Dutch are not very well known for politeness, not in general and not in traffic. No exception for the waterways. Basic rule when approaching a lock is, of course, waiting your turn. Even, if it is not possible to wait-in-line, it should be first come, first in. But do not be surprised, if you have been waiting some time, and someone passing the full convoy of ships waiting and simply entering first! We once were in the line with our English friends when such happened - frankly no surprise to us, but our British-skipper could not believe his eyes.
We ourselves rest our case, when such happens. But sometimes others go after, and make the lock a battleground. We would not advice. Being on the water should be relaxing, after all. Just take the next turn. Sometimes the
impolite try the same trick, with commercial barges (by the rule, they should be entering first, as they have the right of priority). Watching this happen, can be great fun. Imagine what a large barge can do with its
propeller to a small yacht, being in the same lock!
Another basic rule is, when arriving in a crowded harbour to moor, one should be allowed to moor next to another yacht. Asking permission is a good habit, giving permission obliged. Almost suddenly adults start playing "hide & seek". When a potential neighbour is arriving, just pretend you're not there, this sometimes seems to be name of the game. Helping hand to reach for the lines - yes it is the rule that gives the "community-feeling" on the water. But not for all skippers, unfortunately. On the other hand, it could be the case that someone is mooring next to you, steeling your view, even when plenty of space is available on the
quay. Just keep laughing and start a chat about the weather, a famous Dutch hobby.

Speeding with
Bayliners is only allowed on very few places, most of them on wide parts of the large rivers (
Maas, Rhine). So, on those wide parts, pass as close as possible. Such offers the largest fun with the waves and the small dinghies just passed by. Sorry folks, quite a few have Dutch or
German flag... Remember the Netherlands have strict
speed limits on the highways, so as prudent fathers we go to the Autobahn of our neighbours to see (and show) how fast we can go.

We have experienced only the Italian skippers in the Venice laguna can do better.
Waving to each other when encountering another ship is a nice and pleasant attitude. Frankly such is not done with a middle finger up (we could not detect a flag, so no nationality offended). What about the
English skippers that more and more can be found on the Dutch waterways.

They are very polite and
recognized as such by there British flag. So, sometimes simply by showing this, they are given way by other skippers,
lock keepers and
bridge masters. I think such is not fair! And, by the way, not everything in life is negotiable!
On Dutch waterways we do not have much experience with
French skippers. Maybe we are just lucky. We have in France - but that is where you best can do as the French do (with a hired ship, of course). Just pretend the
quay is not there, the bump will not cause too much damage to the plastic.
The
Americans - some hire ships in Europe - are
ok. They do it by the rules. As we once noticed an American
crew member saying when she was supposed to moor with the aft to
quay: "but this not in the book!".

The
Australians - yes, they can be found on European waterways as well, enjoying our cold and wet climate (seriously!) when sun is heating their desert - are used to a lot of space. As we once noticed them taking full length of the
quay to dry their wet laundry.
Glad we have given our ship the Spanish name
Cómplice. Never met
Spanish skippers on Dutch or other European waterways. Only know Columbus. So probably they are the best.

Don't be frightened - all this happens once in a while, but of course it is just a caricature. Sailing and motoring on Dutch waterways is just big fun.
