It's 320 hours or so, but only 13-15 days. I think most would monitor carefully, might select a synthetic or premium oil, and would be diligent about filling along the way. In an engine that's in top shape and running well, been changed just before the trip, then it really shouldn't be an issue. I would consider that a reasonable choice whereas I just wouldn't want to shutting the engine down in the middle of the ocean or trying to run on the get home system.

I pull an occasional oil sample on my Cummins. Lab says at 200hrs oil is still in good shape, and this includes some hard runs, short runs and runs at very low power. I change at 300hr.

Some engines at light load pick up fuel dilution from incomplete combustion, that could be a bigger problem than soot load.

Running at 1600 rpm, 7 knots, no Paravanes.

I think the prop recon makes at least a 0.5 to 0.8 knot diff.

Thanks guys, you shamed me into doing right!

It looks like they're making pretty good time. . . . until you zoom the map out to where the departure point is on the left and the destination is on the right.

That is when the enormity (the Holy Crud!!) of the trip sets in!!

Or you can always draw out a couple quarts and add it while running...as long as your pressure and temp stay fine...no big deal.

Or amazingly enough...even the middle of the Atlantic can get calm enough on a trip to shut down and change the oil...not my choice as shutting down in some of the places I've been in boats and helos was a no-no even though we trusted them to start when we needed them...just didn't take the chance.
They could have just monitored their oil usage before the trip and are adding oil accordingly. Or perhaps they installed Murphy gauges where the can monitor all their fluid levels while the engines are running and add as needed.

Where do you anticipate his next stop is? I haven't backed the map out enough yet.

Okay, looks like Azores and that is one long trip.

Good to see they are on their way again.
Looks like good speed as well.

Re oil usage, once you have used an engine long enough you know the consumption so just add the appropriate amount every 24 hrs or so.
300 hrs with out a change will not be a problem when running at good load.

Pretty exciting ( or boring) trip ahead.

Cheers
Benn

My guess is Flores Island, Azores....only 1680 miles or 280 hrs/12 days at 6 kts!

You da man, Richard!!

Noticed that yesterday too. Would provide updates every 10-20 minutes for a while and then nothing for an hours or so. Don't know enough about the system to really even guess!!

Yeah. I think I'd prefer boring, but I'm sure they will have their moments. When you''re that far out, every little unrecognizable squeak, creak or grunt or vib is a "moment". One evening at my dock, I was aboard a friends boat who probably had more cruising miles aboard boats in blue water than anyone I know. A couple of dolphins were playing below the boat, probably chasing a school of fish. Suddenly there was a loud thump on his hull (something I had heard many times while docked there with my own boat). Even with all his experience, he stood up (obviously startled) and said he had never heard anything like that before.

Water, and what goes on beneath a boat, can often make for those moments.

The oil change issue shows one, unmentioned, advantage of twins-shut one down, change the oil, fire it up and do the other one!

The 42' KK that recently did the Galapagos-Marquesas trip I think did shut down mid-ocean for an oil change.

I've talked to several who have made the crossing and it's funny how different it is for each of them in terms of enjoyment, trouble, fear, weather, conditions. There have been some where the boat was put on the market for sale as soon as they reached the other side. But others saying it was the experience they hoped for plus some. I would think only having two aboard to share the helm would be tough. Especially since it also denies the two of you common experiences much of the time as you're simply not together. But we're all use to different paces. Our longest single leg of our Alaska trip was 760 miles but we had plenty of helmsmen and were never bored. I think about the time they hit the midway point the enormity of the trip will hit them when they realize how far they are from the nearest land. They seemed extremely well prepared and I'm betting on a great experience for them.

Yeah, those thumps, squeaks and different tones you here every now and then always get my attention. One of my buds is a long haul trucker, he says the same thing about his truck. Back and forth from South Texas to North Dakota year round w/ oilfield equipment.

Someone earlier mentioned the drone of the engine, and that's what it is. Comforting, reliable, steady. Soothing even. It'll be those odd, out of place noises that get your attention, be they engine noises, the water or something in it.

Just curious - does a KK-42 typically have a wing engine or some sort of aux power source? Not that I think they will need such a thing, but I'm not familiar enough with the KK 42 to know.

In my experience the majority of Krogen 42s do not have a wing engine or other get home device. Many, including Bay Pelican, do. It is more come on those boats which are taken offshore to the Caribbean, Mexico or Central America. A 27 hp Yanmar was a favorite wing engine to be installed. Provides 4kts in normal seas.
