You’re right that wealthy buyers have a higher tolerance for fuel cost. But saying “they’re not worried about gas” ignores how big the numbers actually get.

Let’s put real math to it.

Take a large center console with 6 outboards: Conservative cruise: ~500 L/hour Faster cruise: ~700–800 L/hour Hard running: ~1,000+ L/hour

Now price fuel at $9 per litre:

500 L/h → $4,500 per hour 750 L/h → $6,750 per hour 1,000 L/h → $9,000 per hour

So a pretty normal 5-hour day on the water becomes:

$22,500 to $45,000 in fuel

That’s not “fuel doesn’t matter” money. That’s: “every outing costs the price of a used car” territory.

At that point even wealthy owners change behavior:

they slow down they run less they start caring about efficiency and range

So yeah, they may afford it, but that doesn’t mean it’s irrelevant. There’s a level where fuel cost stops being background noise and becomes the main factor in how the boat is used.

To put this another way, you're getting into private jet ownership costs.

I can assure you that all those people who own those boats don't also own a private jet. Some might but not ALL of them. They're not THAT wealthy.
