Hi VLD549. I only changed the Dutch name of the gulf. The English name is still according to your spelling. You can verify my Dutch spelling on different, independent webpages: "https://atropatravel.com/trips/boat-trip-in-pelion/?lang=nl" and "https://www.grieksegids.nl/pilion/afissos-pilion.php". The name "Golf van Volos" is assigned to the small bay right at the south of Volos, so both are existing and not the same. The Wikipedia is not correct by suggesting that both name are assigned to the same including the spelling. Before my change the entire gulf was named "Golf van Volos" but this is definitely wrong. Please check in Google Maps. If you want I can separate the two gulfs from each other in OSM. Then it will be fully correct. Many thanks for your effort!
