I'm going on a long sailing trip in Netherlands. I would like my family to be able to contact me in case of an emergency, but we'll be outside of mobile network range most of the time.
Along the German coast, the DP07 network can send out your messages on VHF against a fee, but does something similar exist in Netherlands? It seems that Scheveningen Radio used to be a thing, but I can't find any information on other private VHF stations.
Edit: I went there and it had solid 3G coverage at all times, including along the western Northern Sea coast
