“n my mind the biggest issue is how difficult it is for someone to get started. Getting enough rides to become addicted. ”
Unless you were born into a course-skiing family most skiers I know started with a sub-optimal situation. But they knew someone - uncle, neighbor whatever - that could throw up a wall of water and that seemed pretty cool. I’d say for most people some element of skimming over the water, or showing off, or hanging with friends was the hook. Awareness of six turn buoys came later.
Getting started does not require a direct drive inboard on a private lake. In fact if we define it as such, it’s absolutely exclusive. I live in MN, so skiable water is a non-issue. Winter is an issue, but that provides other opportunities.
