Charleston Arrival

We completed the final leg of our passage from Horta to Charleston in the same conditions as we started, with light winds, calm seas and great speed. In the middle, we had two weather systems to contend with, including the first named storm of the year, tropical storm Ana. With the storms behind us, the last week at sea was enjoyable and uneventful from a weather perspective, but we did discover a problem with our main engine accessory drive belt. This required stopping the main engine and running on the wing engine briefly to replace the drive belt.

Ship traffic slowly picked up as we approached the US, and we heard our first US Coast Guard radio transmission in four years when still 300 miles out. We cleared through underway via the US Customs mobile app and were able to get our first COVID-19 vaccinations within two hours of landing. We also took Spitfire to the vet for a thorough examination, and took delivery of dozens of Amazon packages. It’s great to be home.

At 2,922 nautical miles, this was our third-longest passage (compared to 3,689 nm from St. Helena to Barbados and 3,023 nm from Australia to Mauritius). We’d routed the passage to run south of the near-steady procession of intense low pressure systems flowing eastward from the US Atlantic coast. This strategy had been successful in keeping us out of dangerous weather, but did add hundreds of miles to the trip compared to a direct run.

The summary data for the passage from Horta to Charleston is:

  • Fuel consumed: 2,519 gallons (9,535 liters)
  • Fuel left on arrival: 178 gallons (674 liters)
  • Total distance: 2,933 nm
  • Overall fuel economy: 1.16 nm/g (0.31 nm/l)
  • Overall speed: 6.35 kts
  • Total travel time: 19 days, 5 hours
  • Fuel rate: 5.45 gal/hour (20.65 l/hour)
  • Average RPM: 1718

We arrived into Charleston almost a month to the day after departing Dublin. The overall statistics for the entire Atlantic crossing, from Dublin to Charleston with a two-day stop in Horta, are:

  • Fuel consumed: 3,670 gallons (13,892) liters)
  • Total distance: 4,263 nm
  • Overall fuel economy: 1.16 nm/gal (0.31 nm/l)
  • Overall speed: 6.54 kts
  • Total travel time: 27 days, 4 hours
  • Fuel rate: 5.36 gal/hour (21.31 l/hour)
  • Average RPM: 1723

700 Miles
We’re only 700 miles out of Charleston now, and should be there in four days.

Storm Ana
Subtropical storm Ana, the first named storm of the season, to our northeast near Bermuda. We’re really glad to have put several hundred miles between us and that system. We figure it cost upwards of 500 additional miles, but from the size of that storm, worth every one of them.

7.7 Knots
Our speed has been as low as 5.5 knots in the past 12 hours, but we’re currently humming along at 7.7 knots with a fuel economy of 1.13 nm/gallon. The winds are less than 5 knots and our pitch and roll is a comfortable 5.8° and 6.1° respectively.

Deadline Mode
Now that we’re a day out of Charleston, we’ve set our “drive to lights” system into deadline mode to arrive at the marina at 8am. Instead of indicating we should speed up or slow down based on a fuel economy goal, the system now guides us to arrive on at 8am.

Hidden Failure
In a great example of one failure hiding another, we both noticed some black dust around the front of the engine and both assumed it was due to the exhaust leak. But when bigger pieces such as the long narrow one roughly at center started showing up, we noticed it, picked it up, and found that it was rubber rather than soot. If it weren’t for that larger piece, we might not have noticed. The rubber is obviously from the main engine accessory drive belt.

Running on Wing
To check on the main engine accessory drive belt, we need to stop the main engine and run on the wing. With only had 20 hours of run time left to reach Charleston, it would be easy to just hope that the belt could hang on that long and not go to work on the 180°F main engine in the 117°F engine room. But if the belt breaks, coolant stops flowing and the engine overheats very quickly and it’s possible to do serious damage before an operator acts on it because it happens so quickly. So we started up the wing and shut down the main to investigate. The wing tachometer is visible, showing 2342 RPM, below the main engine tachometer.

Belt Separating
It’s a good thing we did check on main engine accessory drive belt condition. It was in rough shape.

Belt from Top
Another view to the main engine belt from the top. It’s in astoundingly poor shape. None of the idlers appear to have bearing problems, but there’s no way a belt this new should fail. We only have a used belt in stock, since we just changed this one. We’ve got a couple of more belts on order, but we need to investigate what caused this failure in more detail. It’s possible that a new belt stored 12 years could break down, so it’s conceivable that its just a belt failure, but we won’t conclude that until we check everything else carefully.
Click for larger image
Used Belt
We don’t have a new belt in stock, so we put the best used belt back on. It’s in very good condition and should last well. We’ll watch closely to see if there’s any signs of wear, and we’ve got a couple of belts on order. Once we get those, we’ll put a new belt on and very carefully check for any sources of problems.

Watermaker
Dirona’s water maker is equipped with a media filter (essentially a small sand filter similar to those used for swimming pools) prior to the pre-filter. This has the upside of allowing our media filters to last an entire year, and we just have to backflush the media filter every couple of months. It’s due today and so it’s being back-flushed overboard. the slight color visible in the water means it’s not quite clean yet.

Vet
Spitfire having his blood pressure checked at Charleston Harbor Veterinarians via a cuff on his tail. He’s been having trouble with his hind legs collapsing, so we took him in for a full examination and bloodwork. We suspected possible low potassium levels, a common problem for cats with kidney disease, but all his blood readings were close to normal. He’s still playful, and gets around fine, but he’s getting a lot more cautious since sometimes his legs let go.

    Spitfire loves his new bed but would have preferred the box it came in.

  2. Welcome home Jennifer, James and Spitfire! Good to see you are healthy, been vaccinated ánd got the check-up from the vet!
    I’ve enjoyed the boardings of Spitfire in the cathotel! Give him a big hug from me! 💖

    • Wonderful to hear from you Monique–we sure miss the excellent care Spitfire had with you at Het Catshuys. We wish we were still in the Amsterdam area. Any interest in moving to Seattle? It’s quite nice, and we could really use your help there. :-)

      Jennifer, James, and Spitfire

      • jan-kees says:

        Monique, if you go to Seattle, I’ll throw in free use of our boarding and medical practice management system for veterinarians, hosted on Amazon AWS. NO I am NOT mentioning our name here, since this is not an advertising medium.

  3. Dean Russell says:

    Welcome Home, Long time follower.
    I was wondering about the amount of fuel you had on arrival. How close was that to your estimate.
    When you got close to the coast, is there a tendency to speed up, consume more fuel because you know you are going to make it, or rather a slow down or steady due to desire for the trip not to end.

    • Our arrivals will just about always be exactly as aimed for since it’s all monitored automatically but, your right, there is a human tendency to consume more when close. In this case we were aiming for 200 gallons of reserve fuel but when working across the Gulf Stream in 20 kts of wind it was fairly rough and very slow going so we ran at full speed through the final segment to get back on schedule since we had appointments that day for vaccinations and a Veterinarian visit. As a consequence of pushing a bit harder for the last 12 hours, we arrived in with 178 gallons (https://mvdirona.com/2021/06/charleston-arrival-2/).

  4. Per-Ola says:

    Welcome back!
    As always, amazingly interesting to read and follow the adventures of Dirona, Spitfire and the two of you.

    Any plans to come back to Seattle in the near?

    And as a Seattle Swede, I’m of course curious to hear if you ever got a chance to try this (https://mvdirona.com/2008/03/swedish-stern-tying-variations/) when you were back in in my native waters two summers ago?
    (I totally forgot to ask back then)

    • Thanks for the welcome home. The boat will be staying on the East Coast but we will be back in Seattle in July for a month. We did considerable boating in the Stockholm Archipelago. We never tied off as the local do but we can confirm it is common.

      We were planning to spend the summer in Sweden and Finland this year but as we neared from Norway, the border to Sweden was closed to non-essential traffic so that trip will have to happen at another time.

      • Per-Ola says:

        Well, you did select wisely, as Sweden last week (5/28) decided to keep the borders closed for people from outside EU/EES until at least August 31st.
        Plus we got to read about yet another Atlantic Crossing (and not the Norwegian CrownPrincess’ – reference to a great series on PBS).

        Knowing you’ll be more than busy back in Seattle, but if you have time for a coffee meet while here, I’m all game (I’m in Kirkland but of course mobile)

        • Sounds good. If you feel like dropping into the core of Seattle, we can grab a coffee or a late afternoon drink over the weekend of July 11 and 12. If you have time and inclination drop me a note towards the end of that week (jrh@mvdirona.com).

    Welcome home!

  6. Luc van Herle says:

    Welcome back to the US. I have been following you on YouTube for quite some time. I love how methodically you approach problem solving. Watching you replace the generator was like watching master class. Always fun to see Spitfire coming to inspect and supervise your work. I know you prepare to the n th degree for these things, but you sure make ocean crossing seem routine.
    Welcome home!
    Amazon is glad you are home as well.

  7. Michael Crofts says:

    Concerning the serpentine belt failure, I dislike the belt covers on our LP668D engine because I cannot inspect the serpentine belt in any meaningful way. Have you ever thought about having perspex covers, or even perspex windows in the solid covers?

    • Hi Michael. I find with a flashlight, I can see in through the front grating to inspect the belt fairly effectively with the current covers. That’s how I saw this fault. Annually I remove the covers, remove the belt, inspect it carefully, and then inspect each idler, tensioner, and accessory for noisy or loose bearings. Seen in this video: https://www.youtube.com/watch?v=sB9I4N5mRGw.

      Since I believe that the cover have to come off at least annually for full inspection and I can see through the front fairly well for between major inspections, I’ve not considered creating windows or moving to a clear cover. There is no question that a lighter and easier to handle cover would be nice.

  8. Erik says:

    Thank you very much for sharing your travels and stories. It is really great reading about your Atlantic crossing just like the other passages with Dirona. The technical bits and all the things you encounter when planning and making such trips are very valuable. With the belt failure that you had the other day; does it take long before things have cooled down enough on the main engine to replace the belt? I guess for the tension it is also important that it is mounted when the engine is cold. Thanks again for the great reports. Regards from Amsterdam

    • I didn’t wait for the engine to cool down and changed the belt immediately and, yes, the engine is really hot. I have a set of thick leather gloves that slow me down a bit by limiting dexterity but it does allow me to work on a hot engine. Unlike V-belt designs with fixed tension that is set by moving the alternator or some other accessory, serpentine belts (flat belts with longitudinal grooves) usually have spring loaded idler pulleys which require no adjustment. With these idler’s, you can just engage a wrench in the tensioner, pull it back, and lower it back down on the belt and the tension is set and correct.

      In this particular case, the belt is changed and the covers are all back on in 10 to 15 min, so the engine has barely cooled at all during the job and only needs to be off for 15 min.

  9. Alexander says:

    Hello and Welcome to the US!

    I have been reading and following you guys for many years. Thank you for all of your time, effort, patience, and guidance during your passages, it has been a game-changer for me truly understanding the world travel on a Nordhavn in real time, I appreciate everything!

    Q: Now that you had your N52 for a while, do you have any plans to upgrade for a newer Nordhavn model?

    • Thanks for the feedback on the blog. We appreciate it. You asked if we plan to upgrade Dirona? It’s certainly possible but not likely for the next year or so. We still really like the boat and find it continues to serve us well. We still feel like to have it.

  10. Pete Jarvis says:

    Welcome home. Good karma flying your way. An amazing experience.

    • Thanks Pete. We’re both happy to be back and thinking of doing a cross country road trip in the near future so you may see an SUV rather than a boat for a couple of weeks :-).

  11. Wyatt says:

    Welcome home!

    • Thanks. It’s great to be back. If you noticed the Amazon stock price climbing suddenly, it’ll be the impact of our ordering. It’s amazing how much is needed after 18 months. Love Prime shipping!

  12. George Hanna says:

    I have been following your blog for a very long time and i truly enjoy it. is there a software or any type of app that help passage makers, especially small boats vs ships, that can help the users make better decision based on a large set of data and real time access to weather information and historical crossing. Maybe Amazon can come up with an AI solution, where we can simple file our trip before we leave docks and then get updates as need to, to minimize data usage from satellite. We have the auto driving feature in Tesla and autonomous vehicle and even trucks in the future, and why not assist boaters in their ocean crossings. Just wondering, i learned a lot from what you have published in your blog. I appreciate it.
