How many people does he have to share helm duties on this leg?

These are what Richard said were his averages for the trip from Providence, RI to RI to Ireland.
Average = 1.59 gal/hr.
Average 3.6 nm/gal= 1.7 km/liter

Looking at the pilot charts, he should have .5kts current with him. Don't know what he had going over... Speaking from personal experience the sea state on these particular hulls makes all the difference.

Found this
More than 200 Krogen 42s have been built, and all but a handful came equipped with a single 135 hp Lehman diesel powerplant. While this hull form is limited to its displacement speed, as opposed to some trawlers with semi-displacement hulls, the Krogen 42's fuel consumption is truly miserly. With its standard fuel tankage, the boat comfortably cruises at 8 knots, with range of up to 2,150 nautical miles. Pulling the throttle back slightly results in an incredible 5,000 mile range at 6 knots, for those who appreciate the journey as much as the destination.

So, if his tankage is 700, that would give him range at 100% of 2520 nm? Surely, he has more fuel or bladders or something and not cutting it that tight.

He can significantly increase range by a small reduction in speed. I'm sure he is closely monitoring fuel rate and load.
Also, on his trip east, he made a fuel stop that allowed him to push a little harder for at least part of the trip.
Looks like when he gets into some weather, it will be predominantly following seas. If it was head seas, his burn rate per mile could be real trouble.

Latest update from Richard. "Winds now 090 to 120° ,10 kts. This way for last 24 hrs. 15ft swell from west Wind waves ftom SE, one bird still in water. I'm wanting to get further south to put us in the northeasterlies."

Dauntless Crosses the Atlantic Again
Here's some more stuff for those of you following Dauntless's return trip.
EOD stats day one: distance run 141nm, avg speed 5.89, course 250true, engine speed 1500 rpm, fuel rate 1.4 gph.
Fuel used over the previous run of 171.8nm from Las Palmas was 47.6 gallons over 34.25 hours running between 1500 and 1600rpm. Due to currents and having both birds in the water he averaged 3.6 nm/gal.
With a fuel load of 700 gallons he figures he has a range of 500 hours run time at 1500-1600 rpm. 2500nm/500hrs =5 knots and is his sog reference point. He has been running on one bird at 5.8kts and 1500 rpm for the last 36 hours. Tonight he pulled the remaining bird as winds and seas diminished. At his halfway point he'll re-evaluate. Running 200 rpm less he'll burn 1.1 to 1.2 gph, and as his fuel level goes down his speed will go up.

You remember correctly. I was afraid he was going to have to row Dauntless into port .  
Later,

Yes he did come in of fumes but when he fueled up in the Azores to head to Ireland he did not completely top off. He wanted to keep the weight down. Then he ran into awful weather and ended up taking a less than direct route. Hopefully he will not need to do that this time. He is dealing with some prevailing westerly trades. May the fare winds and seas be with him.

Much thanks to those of you providing the updates. I've been following along and watching the tracker.

When Richard was eastbound I believe he reduced his speed substantially in order to get higher mileage. With the same boat and engine we generally cruise at 1400 rpm and in seas without a current average about 6.5 kts.

Some more updates from Richard. "Seas are 2 to 4' wind driven fron SE. Larger Atlantic swell is much lower now. Maybe 8' from WNW. This combination causes a large cork screw motion. wo paravanes now, larger roll is +10° to -10°, while smaller is +-5°." This update his position info was:
Speed: 7.13 kts
Heading: WSW
Elevation: 21.00 ft.
Lat: 26.731076
Lon: -21.792305

Dauntless Crosses the Atlantic Again
Richard runs Dauntless on Greenwich mean time and his watches are 0400 and 1600. He gets bored, so do send him a note of encouragement via his delorme device on the delorme web page. Also for those concerned about his fuel and range, I found an old set of curves for the krogen 42 from Beebe's book.
25 years ago I was convinced that the 42 is a remarkably efficient hull. Today Richard, and many others keep proving it.

If ya think KK's have a "remarkably efficient hull" then you'd be even more impressed with the George Buehler Diesel Duck hull lines... About as fuel efficient as anything out there.
Note: Slightly biased opinion of course... but it is based upon actual data.... just ask any Duck owner.
Not to mention a typical Duck's fuel capacity is almost three times that of a KK 42

No need to
make this thread a competition between trawler builders...
This guy is just doing something that most of us would never have enough balls to do it.
Lets encourage him, check he is safe and be humble looking at his adventure.
