I am only referring to regulations, not practice in real life. I guess if You are having any boating certificate issued in Netherland, you automatically are expected to comply with inland water regulations. But as an example, UK and Finland do not acknowledge or comply locally with CEVNI, our ICC don't include the inland waterway competency. That's why we need to take the CEVNI course. I think a dutch ICC do include inland waterway competency, that is the difference.
As guessed zubol does not have the inland waterway competency, I just wanted to show him the correct direction. CEVNI requirements is also mentioned on among others on the RYA web pages.
Cant find any source confirming a foreigner boating in the Holland channels does not need a proof of inland waterway competency, but if that is really the case I stand corrected, no issue at all.
