"they are significantly cheaper to operate (with diesel) than a 38ft gas boat, probably half as much."

This is only true if maint , oil changes , filters and repair parts are not counted , and the gasser is operated well above trawler speeds.

Operate at the Sq RT of the LWL for speed in Knots as many trawlers do (-30-50 hp) and gas is cheap to keep.

A vacuum gauge is a great help on a gasser , to stay below the secondaries opening , if you want to go a bit faster.

"Plus I think they just look cool."

Ego is expensive ,

A $4.00 spark plug vs a $75 injector rebuild , the requirement for super cleaned diesel fuel and the ease of repair make the seasonal or annual cost of diesels at least on par with gas.

Now if you run 200 -300+ days a year the diesel will have an advantage in fuel cost , and the higher repair PM costs can be OK.

At local cruising 200 hours a year many times a gas boat is a far better buy , the difference in interest on a loan may pay for all summers cruise
