Hopefully everyone is out there enjoying their boats! I havnt seen a new post in over a week.
We took delivery of an 09' 4460 almost 2 months ago and are having a blast. I was a little cooncerned with fuel usage but I am pleasantly pleased with the economy of the IPS w/joystick. I am burning far less fuel than I did the last several years on my Silverton 392 diesel. Also she has a fuel flow meter that has taught me alot about cruising at low speed. I was always under the impression that if I cruise 9-10 knots that i would be saving alot of fuel. With this boat if I am cruising rb2@gr5t 10knots I am burning almost what I would at cruise. about 2 miles per gallon. At cruise I am at about 1.2mpg. If I drop her down to 7kts. I am getting almost 4mpg. burning about 2gph. Amazing difference in only a couple mph.
Not going faster than hull speed (sq root of water line, LOA of INWATER part of hull,times 1.33 equals hull speed.)works great as a rule of thumb. I have substantially saved on fuel this yr.
the fuel flow meter also tells me the best spot to cruise at. My optimum is at 3000rpm and 29mph. depending on wind and current it can range a little either way. If you dont have a fuel flow meter you should think about it. I guarantee it will pay for itself in no time. It will definately increase your time on the water instead of the dock.
I am interested to hear how everyone else is doing and are we using our boats this year?
