Sounds like he has some good margin in fuel load.
Do you mean I am looser?

Guys, from our last exchange I feel Richard starts to feel tired. It would be nice from you to send him some encouragement, I am sure he would appreciate it.
Go to his onReach and message him your support, pretty sure he will like it.

Yes!, very good idea.
I send him a message.
* This system Delorme in reach sounds to work well. Here we do not use it in Europe..Better than SSB with sailmail?

About the trip, the worth is when you are in the middle of the way. Day afer day with nothing to see than sea, waves, sun...if the conditions are not relax, it is not comfortable.

One more thing, may be: engine noise even loud. When tired, you can be anxious and hear "strange noises"..

15.6 gal per day comes out to be 0.65 gal per hr.

While beating the standard power curve chart for the 135 Lehman at 1.3 gal per hr at 1500 rpm down to 1.1 or even 1.0 might be possible....anyone really think it is down to 0.65 gal/hr?

Most people have always posted that the charts are pretty accurate....

I couldn't correlate this sentence, "It's also confirmed be on 2014 crossing,* sight tubes became useful after the 5th day and by the end of the 9th day, I'd used 400 gal! Vice 150" with what he's saying. Obviously he doesn't have floscan as someone thought he did earlier. I wish he had a means of accurately measuring his use. I'd like to hear how many nm he's covered and how many gallons he thinks he's used, but if he's doing 5.72 knots at 0.65 gal/hr then that's 8.8 nmpg and that just doesn't sound logical. If he's gone 9 days at 1.1 gal/hr that would be 5.2 nmpg which is still amazing. But if that were true, then at the end of 9 days he would have used 237 gallons, not 140. If it sounds too good to be true, it probably is.

Two things helping with the low burn rate: one is his low speed. Averaging around 5.5kts is well below hull speed, a speed none of us would run in the ditch. Too slow. Second is surfing. He's had fairly consistent following seas, combined with the slow speed means a good part of the time the engine is not needing to push very hard.

So I think the burn rate is in the realm of the possible.

Also hard to read sight tubes accurately with pitch and roll.

I told Richard about our discussion concerning putting sails on his paravane rig. He said he had thought about it but the mast was not designed to take a forward load.

I believe Richard said on his west bound trip he averaged 3.6 NMPG and 1.6 GPH.
If he has gone 1350 miles (Hierro to ~where he is, straight line) @ 3.6 NMPG = 375 gallons. At 4 NMPG he would have used 337 gallons. Using the 1.6 GPH, after nine days he would have used 346 gallons. He has what, 1200 miles to go?

And some more:

Quote:
Updated fuel 440 to 460 gal remain. Note, it's very difficult to get better read of sight tubes with boat movement and the engine running.
Atp, I'm sure I have at least 440, likely 460, possibly 480.
1.0 gal/hr seems v reasonable to me.
As soon as we have smooth water, I'll give more precise figure.

We wont know an accurate fuel burn until he fills up. Of course that's just my opinion.

That's an easy fix.

The update Lou Tribal just posted took his fuel usage from 140 or 150 gallons to 240 or 260 gallons used. A big change and far closer to reasonable.

How many miles does he have remaining?

As straight line, it looks to be about 11-1200 miles.

I used 21deg042'N, 41deg38'W, came up with 1570nm to Barbados. I must have goofed somewhere.

Edit- My goof. It is 1570nm from my position!!

NM left in trip comes up around 1130nm straight line, not great circle.
