A summary of documentation required for anyone who's not familiar with European Waterways:
ICC (International Certificate of Competence)
These are obtained from the RYA. You first need to prove for competence though. This can be done by:
a/ Succesfully completing an RYA course, for us that would be the Powerboat minimum level 2. If you've already done this but havent got an ICC then just send your course completion certificate with a fee to the RYA and they'll give you the ICC.
b/ A shorter ICC course can be done at an RYA school. Bit pointless, you might as well do the powerboat course for the money, at least you'll learn something.
CEVNI (Code Européen des Voies de la Navigation Intérieure)
In English "European Code for Interior Navigation". To use European inland waterways your ICC needs to have a CEVNI endorsement. To get this you need to take the CEVNI exam, fairly easy, it's basically colregs for inland. 14 questions in 2 parts, min 5 correct answers in each part. This can be done at a RYA school but also can now be done online. Download your pass certificate, print off and send to RYA for a new ICC.
ATIS is a requirement for European inland waterways but is actually illegal on UK waterways (dont quote me on that though). It is a unique identifying signal that's sent out of your VHF every time you release the PTT. Most modern VHF sets can be set up for ATIS, usually has to go back to the manufacturer, some can be switched on or off. Icom sets have to go back to Icom UK with your Identifying number to be set up, I think they charge £24.00.
To get your vessel ID number you have to apply to OFCOM to have ATIS added to your radio certificate, the number will be your MMSI with a 9 in front of it.
On top of all that you'll need to make sure you have passports, health insurance cards, Vessel's insurance certificate, SSR docs, VHF Operator's Certificate, proof of vessels VAT status if from UK plus anything else I've forgotten.
So don't leave it till the last minute to decide your going on this trip 'cos you won't be!
Edit: You also need a VNF, like a temporary permit to use the waterways. Can be bought as a daily, monthly etc ticket, current prices and other info here:
