Re: 38 dc my fuel economy
I don't know the exact details, but you can figure about 1NMPG at slow speeds (maybe 8 -10 knots) and around 3/4 NMPG at normal cruise...the older four cycle Detroits get about .5 or so NMPG at cruise.

My 43 with 6-71's naturals gets close to 2 mpg at hull speed. Push her to 14 kts and she does about .6. Bill
