The current plan is for Sans Souci to stop in Ensenada on Friday, take on some fuel, then cross the border into the US and arrive at Nordhavn’s facility, in Newport Beach California, on Saturday. I’m not sure how long the boat will be at Nordhavn. There is some work to be done, but other than a couple of small projects, all of the work can be performed in Seattle when the boat gets north. It may be a two day stop, or a two week stop. I sent an email earlier this morning to Nordhavn to get their thoughts.
And, returning to yesterday’s discussion on fuel….
I forgot to mention that all of the numbers presented included a 25kw generator running at all times (approx. 1.5 gallons an hour). On a major passage, I might be able to run without the generator most of the time, so the numbers presented could potentially be improved upon significantly. The alternators on my main engines each put out 100 amps, at 24v, for a total of 4.8kw. Without the air conditioning, this might be adequate to keep the boat going. I’m not sure.
There was a question posted yesterday about whether the second N68 had different engines than my boat. The answer is: yes. I have twin Luggers (a marinized version of a John Deere engine), and the second N68 has twin Detroit 60s. Thus, there is a chance that my boat’s performance will be slightly different. My guess though is that any difference in fuel efficiency is negligable. The horsepower requirement to move his boat, and my boat, through the water at any given speed is the same. Diesel engines are what I would call a “mature industry.” I haven’t directly compared the two spec sheets, but my guess is that if I match them at a given horsepower the fuel consumption will be within a percent or two of each other.
Also, someone asked about the website for the second N68 – the website address is: http://www.graceoftides.com/. However, there’s no need to click the link, because there is nothing there. David started the site, then decided to start it over, to make it better. I’m not sure if he’ll work on it again or not. I’ve been lazy about updating my own site. Other than the blog, I haven’t updated it in months. Oh well….
We had dinner last night with the owners of an N62 that is crossing to Japan with us next summer; Steven and Carol Argosy from the N62, Seabird. Whereas I have refused to think beyond Japan, Roberta and Carol had no such hestitation. While Steve and I were talking boats, the ladies were plotting all the interesting places we can go once we cross the Pacific; Papua New Guinea, Indonesia, China, India, Thailand, etc. Roberta reminded me once again as we were leaving the restaurant, that whereas I spend a lot of time whining about crossing the Bering Sea, that it is really only 20 days, that will be an adventure, and that once on the “other side” we may never see cold water again.
Steven mentioned that he had just added a “hydraulic generator” to his boat. I have heard of hydraulic alternators, but have never heard of a hydraulic generator, and still don’t know that I completely understand the distinction, if any. He said it is the generator-side of a normal generator, but powered by a hydraulic line coming from a hydraulic pump, powered by the main engine, or his wing engine. It is giving him 20kw of power. I mentioned that I had hydraulic alternators on my boat that I haven’t been using because they seem no more efficient than the generator, and he pointed out that there is no oil to change, or impeller to change on his hydraulic generator. A great point. I change the oil on my generator every 200 hours, and it gets annoying after a while. My generator tends to run 24 hours a day when away from the dock, so this means weekly oil changes. We have a oil change system that makes the oil changes very simple, but its still not fun. I may give my hydraulic alternators another chance… (I have approx 12kw from two hydraulic alternators).
One fun piece of triva we discovered last night was that twelve years ago, when Roberta and I were thinking about buying a Nordhavn 62, we visited a Nordhavn 62 named Atlas, that had just arrived in Seattle from Australia. When I mentioned Atlas, Steven said “That’s our boat! We renamed it!” Steven has cruised Seabird to Seattle from the east coast. It’s amazing how these boats get around, and it seemed kind of cool that we would be crossing the Pacific in the company of the first Nordhavn 62 we ever saw.
