Hi,<br /><br />I have been asked to go on a trip with two other ribs which is a channel crossing of 40 miles. I have a 1900LSR Regal Bow Rider with a VP 4.3GL 190bhp engine. I have a 30 gallon tank and will carry 12 gallons in reserve. Does anybody have any rough calculations on how much this engine would burn at say 3000 rpm on a flat calm sea. This is just a starting point to see if it looks feasable. If it does I plan to do a 12 mile run then measure the fuel used. <br /><br />Regards<br />Chris
