Fuel consumption of sealine F425

Would have thought Powerskipper would know ...

Sealine's "Alpha" is/was a 42/5 with 74's onboard.... had a bit fun with her in the past.... /forums/images/graemlins/blush.gif the boat that is .. /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif
 
FWIW, I once had a Sealine 410 (very similar hull to 42/5) with TAMD63P 370hp engines and she did about 1.1-1.2mpg at cruise speed which was 20-22kts. At 10kts I dunno as it's not the sort of speed you'd cruise at. Too fast for displacement speed, too slow for planing but I'd guess around 1.5mpg
Try getting an old test report from MBY/MBM
