Gas or diesel, what kind of boat?

We use about 8 gph towing a dinghy in flat water/no wind. *That's with
twin diesels running at 8 to 8.5 kts. *In rough water we hoist the
dinghy up on deck.
9.3 L 570ci 350 hp 1150 ft-lb International single straight 6

* *cruising at a modest 52 kts.
* *37'4" long, Beam 8' 4", Approx 15t, and towing 3700lb dingy. In rough
* water we will sink.

That's more information than some of the scaredy cats in rec.boats are
willing to reveal.

Cruising at a modest 52 knots and a 2 ton dingy???
