It is positively horrifying that some people set out on a hobby to fulfill others, and also that we’re establishing that as financially rewarding. Sailing, in particular, is about returning to the sea and charting your own path. There’s varying levels of mysticism to that in peoples’ relationships with it, but most entry-level zealots, even, would cock their head at the notion of spending your time sailing caring what other people think about it. What is the point of a hobby in the end? If you want a business, call it a business. A satellite dish for YouTube posting means your sailing is a business. And that’s fine. Just say that.
I also considered your entire litigation on the precision of the person’s language before even creating this account. It’s telling that your substantive rebuttal is lawyering the language, not addressing the point. I considered your “couple things” before you said them and disregarded them. You’re arguing that 10% charity in comprehension dispenses 100% of the point. Unsuccessfully.
A couple things. OP is specifically referring to how people make money while sailing (non-commercially) indefinitely, not hobbyists who presumably have a day job, a traditional source of income, or are retired with savings, and sailing occasionally. Also, OP caveats their assertion about social media posting schedules with "most popular boats" - not simply most boats - it's in your quote. If you're not pimping your boat and yourself on the gram (or wherever), you're boat's not going to qualify as popular, and the statement will not apply to you.
