Most economic cruising speed

Wreford-Brown · 06-06-08, 08:51 AM

I know there are a few posts covering fuel economy in the forum and have found the following by using the magic 'search' button:

Type IIA 6 kts (Pisces)
Type IID 6 kts (msalama)
Type VIIB 8 kts
Type VIIC 8.1 kts
Type VIIC/40 8 kts
Type VIIC/41 ?????
Type IX 9 kts (GWX 2.1, jimbuna) or 8 kts (U-104+Brag) - also see predavolk post #5
Type IXB 8 kts (U-104 and Brag)
Type IXC 9 kts
Type IXD2 9 kts

Can anyone verify these figures and fill in any gaps?

IXB 8 Kts.

I think you get marginally, 5% or less, better mileage out of 7 knots in a IXB. Even if true, I prefer the higher speed setting of 8 knots. 8 knots is enough to get you to North America with plenty of fuel left to boot around with. Honestly though, this should be pretty easy to figure out for yourself. Run a straight line of reasonable length as your course, preferably in calm weather, and ask your navigator how far you can go at your current speed. Adjust your speed until you get the longest distance. That's the most fuel efficient speed for your boat.

If your using a Type IX in GWX2.1...9 knots is the average (extra endurance has been scripted in to compensate for the size of the SH3 world)

Type II(a) is definately 6 knots. 4 knots must have been with batteries recharging.

Looks about right AFAIK, excepting the duck A maybe... anyone?
