Currently I'm about to retire and between boats. My wife and I are searching for a long distance trawler like a Nordhavn 47, Selene 53 or KK 48 North Sea. Our plans are to rent out the house and move aboard and cruise until we don't want to anymore. I'm considering getting my captain's license for several reasons - to satisfy my interest in boating, to help with getting my next boat insured, to learn new things and keep my mind active, but most of all to be a safer boater.
What license should I be going for? And in this time of COVID confinement, what's the best option to get it? I live near Newport Beach, CA where there are some mariner schools, but I don't think they're meeting in person now.
I'd like to get your thoughts on this. Particularly from people who have captain's licenses. Thanks!
Twisted Tree's response was excellent. Read it more than once.
Addressing your specific reasons for doing it.
1. To satisfy your interest in boating. An excellent reason to do so.
2. To help with insurance. Experience is what helps. License generally doesn't impact or does so minimally.
3. To learn new things. An excellent reason and you will learn new things.
4. To keep your mind active. Another excellent reason.
5. To make you a safer boater. I'd say by your very interest you are inclined to work on being safer. The classes help. The license doesn't make you safer by itself.
Twister mentioned the wide variation from tonnage to near coastal vs ocean. I must add that now the US license isn't valid anywhere outside the US as it's just a national license so elsewhere you'd need an STCW endorsement to be licensed internationally.
The point is that you're limited by the boats you get time on and then limited by time and money. US 200 Ton gets expensive if you can even qualify, but then going beyond that with to an STCW 500 Ton Endorsement (Careful, a different definition of Tons so still ties to US 200) is even more so.
Now, some dollars and cents, using MPT as my example. Courses for basic US license $999. (With medical and other then you can be there for $1200 or so). However, courses for Master with STCW endorsement is $4950. Not as bad as Masters of Oceans Upgrade to 500-1000-1500 which is $15799.
Continuing education required by a 200 Ton National will likely be another $1000 or so every few years but for it with STCW becomes more like $1000 a year on average.
I'd suggest looking at the various courses and deciding if some of the classes are things you really want. I suspect you'll find that a US National License in the 100 Ton range is your maximum interest and then you may find other courses to take but without targeting an additional license. For instance, if cruising offshore, I'd highly recommend the medical courses, first aid and even in charge. You might find fire interesting and beneficial or you might decide not your thing.
We went for licenses simply for personal knowledge and skills. We kept moving up for the challenge and further education. We maintain as we don't want to give up something we earned. However, I'm not going to recommend doing as we have for you or others.
