My wife and son and I are beginning to plan a year at sea. What are some of the best ways for me to learn what is needed to operate and navigate a large trawler?
The short answer is buy one and learn to operate it by experience.
There are all sorts of things you can do in preparation--- classes, books, videos, etc., etc., etc. In my opinion these can have at least a a degree of value.
When I decided to learn to fly the fellow I chose as my instructor advised me to read a book called
Stick and Rudder by Wolfgang Langewiesche before my first lesson. I did and when I got into the plane for my first flight I knew exactly
why the plane was going to fly and why it would turn, speed up, slow down, go up, and go down, but I had no clue as to how it would feel, how it would sound, how much control pressure and movement would be needed to do such and such, how the plane would respond to inertia, and so forth.
The only way to get that knowledge is by doing it. So unlike a lot of people these days, I don't give very much weight to books and lectures and classes and videos and whatnot. They have a place, but they are no substitute for actually running a boat and learning through experience.
You can never read a book, never take a class, never watch a video and still become an outstanding and experienced boat handler.
You can read all the books and take all the classes and watch all the videos but until you actually get hands-on with a boat you will be no more of a boat handler than you were before you read all the books and took all the classes and watched all the videos. You will simply be a very well-exposed wannabe.
Had I not read
Stick and Rudder I would still have become the pilot I became and gone on to fly floatplanes up and down the Inside Passage, write books about floatplane flying and whatnot. Reading the book gave me some advance knowledge that was nice to have, but it certainly wasn't a requirement or even essential to becoming a proficient pilot.
I daresay most of the people on this forum, and certainly all of the people I know personally who I regard as truly outstanding boaters started with smaller boats and worked their way up. I started with a 17' wood and canvas canoe, then a 12' outboard powered aluminum skiff, then a 17' trailer fishing boat, then the 36 foot, 30,000 pound fiberglass cabin cruiser we still have in the PNW, and finally with the 45' composite newbuild cruiser we co-own in another part of the world. It's been a long journey spanning some 40 years now.
If you want to find out if you are even suited for this kind of boating, a smart way to find out is to charter a cruising boat for a week or two. As you have no experience you may have to charter one with a captain. But this is probably the best way to determine if this kind of boating is for you without plunking down a whole lot of money to buy a boat only to find out that you are perhaps not as enamored of the whole thing as you thought you'd be.
My wife and I first bareboat-chartered a cruiser of the type we thought we'd like to have. It turned out we really enjoyed the whole cruising thing so we subsequently bought one of our own.
So read all the books you want, take all the classes you want, watch all the videos you want, but know that you will not actually start learning until you get your hands on an actual boat and start driving it around. Only then will you find out if you even like this sort of thing and if you have an aptitude for it.
I might even go so far as to say that all the books, classes, videos, etc. that are available today could be a
detriment to learning to operate a boat. You can get so bogged down in the material, and get so wrapped up and concerned over details, that it can become totally intimidating.
There is a degree of truth in the statement "ignorance is bliss." You don't want to be stupid about it, but there is, I believe, some benefit is starting out hands-on with an activity without exposing yourself to the totally bewildering array of "information" out there these days, well over half of which is little more than information for information's sake.
This is a bit apples and oranges, but recent studies in the industry I work in are exposing a rather disturbing trend in commercial aviation. And that is that as commercial airplanes become more and more sophisticated in their capabilities, newer flight crews are becoming increasingly proficient at understanding and operating very complex systems... while at the same time becoming increasingly
deficient at actually flying the planes. This phenomenon has a name which I've forgotten, but it's becoming a disturbingly more common factor in aviation incidents and accidents, some of the more recent examples being very high profile.
The point being, too much information can become a handicap, not a help. So learn to actually
operate a boat. Don't become too hung up on trying
learn all about operating a boat beforehand.
