View Full Version : Best mileage in GWX2?

Owing to discussions in the SH4 forum, I started to wonder what is the most fuel efficient speed for SH3/GWX2?

I had always thought it was Ahead Slow, but now I am not sure. So, what is the best throttle setting? Does it depend on sea state?

Thanks.

Each sub has it's own best speed for fuel economy. I only know type 2 (6 knots). The others you need to search (it has been a reasonably popular subject lately) Or figure out yourself: ask your navigator for max range at certain speeds. High speeds drain fuel, but slow speeds too. There is a maximum efficiency somwhere. But weather (wind) does distort the measurement, so do this in no-waves conditions.

the best mileage can be archived with a hand-set speed.

usually between 7 and 9 knots, depending on the boat. (during heavy seas, probably the same setting would be the most economical altho' the actual speed at witch the boat would move would be reduced)

This was discussed here several times in last two weeks, like here, for example:

That's true, economical speed stays the same no matter what weather, you just sail slower in storms. This indicates that what is named 'speed' on the dials is rather 'engine efort'.

In generalised 'rule of thumb' terms.....1/3 ahead :arrgh!:

Right that's what I assumed, but the SH4 folks have it down as 2/3 ahead for best mileage. So, I thought I would double check. Of course, fuel does seem less of an issue with SH3.

Thanks.

With a VII C at 8 knots you can make it from France to New York and back, and probably do it twice without refueling !

Once doable, twice not unless you row. ;)

I once travelled over 50,000 km in a type VII.........then realised I had the realistick fuel unticked :lol:

I AM SHOCKED! :huh:

Oh...I know...you were testing the type VII with the new and improved VW Bug engine right?
