You used to had a permit to use a VHF radio but from 2008 you just need to register it it with the Dutch telecom authorities.
I am still unsure if you still need to take the exam for the certificate or not, can anyone clear this up?
* EDIT * Found it, could only find info in Dutch but it says you still need to take the exam!

But that doesn't mean you can just use a VHF.
1. The VHF needs to be on a ship
2. The VHF needs ATIS(a callsign which will be transmitted when you press the PTT button)
There is still an other law about transmitting as a public station. I don't know exactly how that
is.
