Hi,
I'm not surprised too much by the 55 mph data. If you tried it at 45 I suspect it would have gotten worse as the boattail would just extra weight. Since at 45 the wind resistance becomes insignificant compared to the other losses. However, if you tried it at 65 or 70, we might see that although the mpg goes down in both cases, it would go down less in the case of the boattail.

Could you rerun the tests at 65 or even 70?
