I doubt the diesels are going to burn half the fuel of the gas engines at
the same planing boat speeds. Also, around here there is almost no
difference in the cost of gasoline vs. diesel. There used to be, though.

I don't know the actual burn rates, so this is purely anecdotal.

When I had the Egg Harbor with a pair of Cat 3126 diesels and 400 gallon
fuel tankage, my brother had my old 26' Phoenix with twin 350 Mercruisers,
recently rebuilt and 200 gallon fuel tankage.

Once in a while we would take both boats with fishing parties aboard on each
out to our secret cod fishing spot, 32 miles straight out from Scituate. We
would run together at about 28 kts. He didn't do it often because he burned
so much gas. The Egg, being bigger and much heavier burned far less fuel
and those Cats were not exactly fuel misers.
