Question! With the 100 ton license can you sail anywhere on Earth? Or is it only for near coastal areas? The video didn't say anything about sailing the oceans.
The license tonnage size is associated with the size of boat you are captaining, not particularly the areas you can sail. There is more to this. A 100 ton boat is not very large. Call PMI-MITAGS in Seattle and ask. Here is a link that may help ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-U73RDpj-r5M.html .
