Boat Rental Clerk -- Completely Specious per the CBP

Some chatter here and there about vocational experts identifying boat-rental clerk as a viable occupation. The DOT describes the occupation:

This description speaks to the rental of watercraft to the consuming public. We know that boat-rental clerk belongs to SOC 41-2021. The OOH tells us that the occupational group has 458,200 jobs in the nation as of 2016.

So far into the weeds, the occupation seems viable. The Census Bureau describes the probable industry:

532284 Recreational Goods Rental

This U.S. industry comprises establishments primarily engaged in renting recreational goods, such as bicycles, canoes, motorcycles, skis, sailboats, beach chairs, and beach umbrellas.

The industry includes pleasure boat rental, yacht rental, and other boats. We can consider and exclude
--

532411 Commercial Air, Rail, and Water Transportation Equipment Rental and Leasing

This U.S. industry comprises establishments primarily engaged in renting or leasing off-highway transportation equipment without operators, such as aircraft, railroad cars, steamships, or tugboats.

This industry excludes pleasure craft and includes commercial watercraft. There aren't any other boat rental industries.

County Business Patterns does not list 532284. It lists recreational good rental under code 532292. The industry employs 9,142 people in the nation. The employment projections state that counter and rental clerks represent less than 23% of the workers in the industry group, 532200. That takes the number of jobs to less than 2,300 jobs (rounding way up). This industry designation includes beach chairs and umbrellas, bicycles, exercise equipment, golf carts, moped, jet skis and wave riders, ski equipment, surfboards, and water skis. The number of jobs as a boat-rental clerk is insignificant.
