The 3800 Open is an awesome boat! It has enough space to be comfortable, yet is not so large to be hard to maintain. It rides well in the rougher stuff and is relatively fuel efficient. It is one of the best hulls Tiara ever designed.

I know of a super clean 2004 located in Florida with the Cummins 480CE engines. The 480CE engines are the same engine as the Cummins 450, but with electronic fuel injection. They are slightly quieter, more fuel efficient and produce much less smoke than the 450s. See below for the approximate performance of a 38 with 480CE engines.

2000RPM 26.0MPH 22.6KTS 24.4GPH 1.07MPG
2100RPM  28.4MPH 24.7KTS 27.0GPH 1.05MPG

2200RPM  30.1MPH 26.2KTS 29.2GPH 1.03MPG
2300RPM  32.2MPH 28.0KTS 32.3GPH 1.00MPG
2400RPM  33.7MPH 29.2KTS 35.7GPH 0.94MPG
