I don`t have an entirely good feeling about this, probably just me. It is great how much help Richard and Dauntless are getting, you guys are wonderful.
The difference between a voyage like this with a powerboat, and a sailboat, is that a sailboat has a near inexhaustible supply of "fuel", provided the mast and sails are ok, greater flexibility when things turn.
Great seamanship, a fine boat, and massive support, should see them safe.

His comment about the pitching got my attention. It's not even a close comparison, but reminds me of a particular day crossing the straight of Georgia. We were running south in 6 to 7's wanting to make Nanaimo, but it was just slow going and we could not easily get as easterly of course as we wanted. The boat could more than handle it. After six hours of jogging in that stuff, I just wanted off the ride. Like I said, the boat could more than take it, but it's one of those days where you have to work, pick and choose almost every single wave. Auto pilot or not, it was just soooo tiring. That was only about six hours. I think the strain here is not the severity of the conditions, it's clearly the duration. Somewhat boring and yet you can't hardly walk away for a real break.

I'm trying to imagine days of this. It's got to get heavy to keep rolling that rock up hill.

I'll be thinking if him tonight. I sure hope he gets a breather by tomorrow.

I just reread #509 and it doesn't explain a 16 nm counter-clockwise loop. It was like he couldn't turn to starboard for a course change. And it wasn't a Williamson turn for a MOB drill. You have to scale to 1 mile per division to see the details of the course loop.

Did Richard top up with fuel in the Azores?

I'm sure he picked up fuel there, but may not have topped up. Sounds like he has minimal margin for landing in Ireland considering conditions.

I too would make nearest landfall (Portugal, or North Spain) to regroup and recover.

Easy to pick weather when you only have a couple day run ahead.

Richard will have to explain what was on his mind at that time. But...

At about that time, the weather reports 48 and 96 hours out were not good and I think the wind and waves around Dauntless were a concern so he changed course. I think this happened fairly late EST, maybe 23:00 or 24:00? I think Richard was finding that the 48 hour reports were not helpful because the weather was moving/changing faster than Dauntless could move.

The lack of information about the current and 24 hour conditions in his area might have influenced his decisions.

I was giving 48 and 96 hour data from the surface, 500 MB, wind, and wave charts. What was most helpful was going to the current charts but we did not know this at that time. 24 hour charts might be useful but they do not extend from the US to Europe. Only the western part of the Atlantic is covered on the 24 hour charts so we have focused on the current surface conditions. I think Richard is using that data to figure out future weather patterns based on local conditions and sets his course.

However, I have been sending 48 and 96 hour data if it looked like there was information that might help his decisions. He has to make decision(s) based on whatever weather data people are providing, his experience, and his local conditions. Some/much of this data is based on computer models and the accuracy of future predictions is problematic to say the least.

I hope Richard has been taking notes on his thoughts and why he has made certain decisions at a given time. This would be very educational to hear. These are not always easy decisions.

Later,
Dan

Lisbon marine weather looks pretty good with wind 15 to 20 kits, pressure steady and waves about 1 meter. But what is it between his current position and Lisbon?

I had a brief text chat with Richard today. I told him to keep the DeLorme working because if he dropped off the grid, he'd have twenty guys calling the CG.

He said "Ok. I wish I had a cat." I think he means a feline type cat, not a two hull boat. He's thinking of my office cat. They became good friends when Richard was living at my store.

Take a look at the animated winds website: earth :: an animated map of global wind, weather, and ocean conditions

I don't know much about weather maps so this helps me see what is happening.
Wind goes clockwise around a high? Counter clockwise around a low?
If you plot his position on this it looks to me that he's headed right into the center of a high. That's good, right?

This morning from a well rested Richard, 5:30 est:

Ok
So I have a juicy question fit the TF.

Set the scene, curr course 008įT, wind 140įat 18kts, seas 3'+- 1'
I just did a trial run at diff rpms, the results

The results:
1300 rpm = 4.5kts
1400 = 4.7
1500 = 5.1
1600 = 5.9

What speed should I run?

More from Dauntless, about sleep, fuel, vessels sighted, watermaker:

Morning,
I had the best sleep ever last night. Almost embarrassed to say, between 22: & 09:30, I must have slept for 8 hrs, getting up only a few times, at

2.
Getting up at midnight and 06:00, and waking only a few times.
I think it's bc the last few days have been hard, but being back on course, let me rest easy

I Had asked him about the water maker:
Watermaker.
I pickled it before leaving Horta, as 300 gal of water is enough for one person and the aux pump died.

It will work wo aux pump, but then I would

I works have had to pickle it anyway in irl, so I figured I may as well stop it sooner.
Also, if I did need it, it's easy to get going again.

Asked Richard about seeing other vessels:
Oh yes,
After 2 days of seeing nothing or nobody. I did see 3 ships yesterday. One, never came up on AIS, but he was more that 8 miles away.

And I did use those ships to see how far I could lower the gain on radar to minimize false alarms.
It confirmed what I thought, that lowering gain down to

Lowering gain down to 5, it still sees big ass ships, me than 5 nm away, but not wave tops.
So another reason I slept better, no false alarms, but no worry

That I was seeing ships.
Also, I used the alarms better, by having a circle, but a mile away.

Had asked him about fuel, (somewhere else he had said he left Horta with 450 Gal):

New fuel figures:
I've used since Horta, 150 g
At 1.2 gal/hr or 4.1 nm/gal
Bc I didn't have full tanks, I've kept rpm <1600.

What speed should I run?

Need the fuel burn /hr too, not just the speed.

Partly in answer to FF and a correction to above fuel use post:

Good question, glad to see they are paying attention.
One corr first, my fuel since Horta was 1.49g/h, & 4.1nm/h These numbers are estimates, like the wx

I would think we need the fuel burn per hour at each RPM that he is asking about. Correct FF?

From Dauntless, 7:07 am, est:

1300 rpm ,maybe 1 or 1.1 g/h
1400 1.3
1500 1.5
1600 1.7
1800 2.0

Now, I can fig out most eff speed, my question is an I missing something.

So, I am not an expert at this but at 1500 he is getting 3.4 kmiles per gal right?
at 1600 3.47 kmiles per gal. at 1300 4.5 km per gal, at 1400 3.6 km per gal.
So 1300 is the most efficient but 1600 is slightly better than 1500 if he wants to cut his time down. I think this is correct?

All of these numbers will vary with the conditions though. And his conditions will change a lot over the next 4 days. I think that is the only think that he did not mention but I know he knows that... Anyone else see anything that he might be missing?

Richard and I are talking about range, and nm per gallon, distance to go, etc. While in a past life I used to teach flying where fuel is king, my boating is I'm going over there, 20 miles away, fuel is never a concern...
I don't want to give him advice, but am gently trying to get the facts straight.

A few texts ago, Richard texted 4.1nm/h

He has replied to my concern about his range at 7:45 est:

Another eek moment
But it passed, your number is gal.
It's 4.1 nm/gal NOT nm/hr which = a knot

It looks like to me he should have enough fuel if he burns at the rates he is talking about. My biggest concern is the rough seas and wind he will be running into starting Sunday evening through Tuesday and what that will do to his fuel burn. I have been using passagemaker.com for my info. Do you guys and gals see the weather that I am talking about. I mentioned the weather concern to Richard and suggested he contact Dannc to make sure that is accurate since I am not a weather person. I have not heard back from Richard.
