A woman asked me last summer whether she should do ASA 101 or just keep taking lessons with me, and she was slightly annoyed when I said it depends on what she wanted to do in three years. It is the honest answer though. Certification solves one specific problem, and if you do not have that problem it solves nothing.
What the card actually does
ASA 101, Basic Keelboat, is a credential that charter companies accept. That is its function. Walk into a charter desk in the British Virgin Islands or on Lake Michigan with 101 and 103 in hand, and they will hand you a boat. Walk in with fifteen years of casual sailing and no paper, and most of them will not.
It also gets you into some club programmes and it occasionally moves the needle on boat insurance, though less than people hope.
What it does not do is make you a better sailor than the equivalent hours spent sailing. There is no magic in the curriculum. The certification measures that you were taught a standard set of things and could demonstrate them on a given afternoon.
When it is clearly worth it
You want to charter. This is the whole case, and it is a good one. A week on a boat in the Caribbean is a genuinely different holiday and the paperwork is the gate.
You are buying a boat and somebody else has opinions about it. A spouse who is nervous, a marina that wants to see something, an insurer asking questions. The card is a conversation ender.
You learn better with a structure. Some people do. If open ended lessons feel shapeless to you and a syllabus with an exam at the end makes you actually show up, that is a real reason and I will not talk you out of it.
When it is money you could spend on water time
You sail with friends who own boats and you always will. Nobody is going to card you at a dock in Wisconsin.
You want to putter around Mendota on summer evenings. Six hours of lessons plus a rented boat gets you there and costs less than the course.
You think it will make you safe. It helps, and it is not the thing that keeps you out of trouble. Judgement about weather does that, and judgement is built by going out in a lot of different conditions with somebody who will tell you what they are seeing.
The cost question
My 101 runs 650 dollars across three sessions. Individual lessons are 180. So the course is roughly three and a half lessons, and it includes the textbook and the exam fee, which means the practical difference is smaller than the sticker suggests.
Where it gets expensive is 103, Basic Coastal Cruising, which most charter companies want alongside 101. Budget for both if chartering is the goal, and do not let anyone sell you 101 alone as a charter ticket.
What I tell people who are undecided
Take two regular lessons first. Not one. Two, because the first one is adrenaline and the second one is information, and you cannot tell whether you like sailing from a session you spent slightly frightened.
After the second one you will usually know. The people who are going to charter have already started talking about where. The people who wanted an afternoon on a lake got their afternoon, and there is nothing wrong with that being the whole thing.
I run the course either way. I would just rather you spent the money on the version you actually wanted.
