licenses are not solas compliant they are STCW-95 compliant, if they are that is....
The USA has also not signed up to MLC 2006
Do not confuse the standard of EDUCATION (STWC-95) with skipper/master/captain RESPONSIBILITIES/REQUIREMENTS at sea (SOLAS) - "sea" meaning: international waters.
Your country does not have to be a signatory of, to be compliant with STWC-95. It however must be a signatory of SOLAS for your licence to be accepted in a IMO (STWC-95 AND SOLAS) signatory country. If it isn't you are most likely not going to be allowed into the country. As I said before, it is a decision of local maritime authorities whether they will let you in or not, and in my experience it is really how the port captain making a decision is feeling on the day.( But if you are on a merchant ship, you WILL be refused the entry. Your company and you personally would pay a penalty.)
IMO manages both, so that becomes a nice after-dinner subject for wannabe seafaring captains to rant about endlessly.
A skipper/etc. must be SOLAS certified. How s/he will get there is not of importance as much. STWC-95 is mostly a minimum requirement standard for education of maritime personnel.
The para from wikipedia shows the greyness of the issue:
"One especially important feature of the Convention is that it applies to ships of non-party States when visiting ports of States which are Parties to the Convention. Article X requires Parties to apply the control (abovementioned penalties for non-compliance) measures to ships of all flags to the extent necessary to ensure that no more favourable treatment is given to ships entitled to fly the flag of a State which is not a Party than is given to ships entitled to fly the flag of a State that is a Party."
What they are trying to say is that all parties to the IMO STWC-95 (as I wrote earlier) can refuse the entry, or slap you hard with "control measures", if your certificates are not up to the standard. What does not seem obvious is that that refers to the responsibilities and requirements of SOLAS. That greyness in understanding comes from the fact that 90% od STWC-95 regulates the training of maritime staff. But, in essence, the training is just a pretext to having SOLAS. If you are a first officer (or any other officer, including mechanics in the dungeons) but do not have the SOLAS cert. you cannot set your foot on a ship that will go to another country.
As complex as appears thanks to the stupid masons who had infiltrated international institutions and polluted the world with their stupid ideologies, it is actually that simple. To be a skipper of a vessel that goes abroad, irrespective of its' size, you
must be SOLAS certified. To recieve the cert, you must be trained. STWC-95 provides the minimum training requirement for you to get the licence and SOLAS cert.
As a few have confirmed here previously, one can, apparently, go between usa and Canada with just a local recreational paper but that is only because of the agreement between the countries that they will treat each other citizens as their own - territorial water sailors.
That removes the need for you to get the full, SOLAS-compliant, skipper cert.
It is (almost) the same as in EU, where you may be able to go from France to Spain with just a recreational skipper cert. and then from Spain to Italy. The condition for that is that you
never leave the territorial waters.
Under the convention (STWC-95 and SOLAS), you may even be arrested by the IMO signatory country for endangering the lives of people on board if you leave the 12 mile limit and venture into the open seas.
And then we, yet again, have the ****** in the usa government who ALWAYS ******** about international "co-operation" but they always have their own rules and laws. Despite signing all the international conventions and agreements. So, while the convention creates the environment for unification (not necessarily a good thing), the usa agrees to it and then goes its own way...
That only creates confusion and eventually a mistrust and a fricken lot of work if you are a maritime officer in charge of documents on a merchant ship. This has been streamlined in the last decade or so but I am not going to go into that side of alumin I um now.
