Managing Fuel Economy

Managing Fuel Economy

We currently are underway on a 3,650nm non-stop run from St. Helena to Barbados. Prior to this passage, our longest non-stop run without fueling was 3,023nm from Dampier, Australia to Rodrigues, Mauritius. The current 3,650nm passage is at the very limit of Dirona’s range and we are, naturally, monitoring fuel economy closely to ensure we…

Fuel economy and range

Fuel economy and range

You never know your boat’s real range until you start to make substantial ocean passages. Theoretical range in flat water with no current and little wind can be surprisingly optimistic so we probe the bounds conservatively.  The 3,023 nm Indian Ocean crossing from Dampier, Australia to Rodrigues, Mauritius is the furthest we have ever gone…

Engine room cooling

Engine room cooling

Excess engine room temperatures are hard on the equipment and tough on the people. Engine room checks end up less detailed and, if you need to do emergency service, it can become a safety problem. We are all sufficiently motivated to want lower engine room temperatures but its actually not that easy. Engine room temperature…

69.1 degrees

69.1 degrees

We bought an ocean-capable boat not because we were convinced we would round the world, but because we wanted the flexibility to be able to go anywhere in the world if we wanted to. We bought a strong boat not because we were convinced we needed to test it, but because we wanted a boat…

A more flexible power system for Dirona

A more flexible power system for Dirona

A little over a year ago, we worked our way south from Fanning Island, Kiribati towards Nuku Hiva in the Marquesas Islands. We were on a long, fuel-constrained run where we would cover 2,600 nm without fueling. For most of the trip, we were heading up-current and into 30 kts of wind on the bow….

A helping crane

A helping crane

Our next-door neighbors, Mark Mohler and Christine Guo of Nordhavn 62 Gray Matter, recently upgraded their davit to support hydraulic power-rotation. The base came off in two pieces, but is much easier to put back together at the shop. The downside is a heavy assembly: the upgraded base, with the power rotation transmission and motor,…

Another Nordhavn 52 is born

Another Nordhavn 52 is born

Earlier this week, Nordhavn 5267 arrive into Brisbane from Xiamen, China on board the freighter AAL Hong Kong. Owners Natalie and Oz Bestel watched from the chase boat and shared these pictures of the delivery. The offloading reminded us of Dirona‘s delivery back in 2009, except of course the temperature was in the 70s in…

Milestones

Milestones

When we traveled from Fiordland to Stewart Island earlier this month, we rounded Southwest Cape, our first of the five great capes. The other four are Southwest Cape, Tasmania; Cape Leeuwin, southwest Australia; Cape of Good Hope, Africa and Cape Horn, Chile. We also reached 47 degrees 2 minutes, the farthest south we will be…

The Economics of Sea Freight

The Economics of Sea Freight

We love Whangarei. It’s a beautiful town, we enjoy the restaurants, and we have the primo spot in the Town Basin Marina in front of Reva’s restaurant. Another advantage of Whangarei is you can get great service work done at reasonable prices. A broad selection of trades is available in Whangarei and that is a…

Dirona Fuel Manifold

Dirona Fuel Manifold

Nordhavn delivers an unusually complete fuel manifold with far more flexibility than most production boats. In fact, the manifold is sufficiently complex that some new owners can find it difficult. More than once, I’ve heard of an owner accidentally closing the return path for the main engine or generator, leading to fuel leaks or, worse,…

Battery thermal runaway

Battery thermal runaway

One of our eight Lifeline AGM GPL-8DL batteries recently went into thermal runaway, and we’ve had a few questions on the nature of the problem and why we chose to replace the full house battery bank. The lazarette smoke/CO alarm had gone off at 3am, and upon investigating we found a rotten egg smell (hydrogen…

On the hard at Norsand Boatyard

On the hard at Norsand Boatyard

Last Friday we hauled out at Norsand Boatyard in Whangarei, New Zealand for bottom paint, zinc replacement and other minor work. This was the first time Dirona has been lifted on a rail-trailer, where the boat is pulled ashore while it rests on a track-mounted trailer. All other times we’ve used a TravelLift, that lifts…

From Hawaii to French Polynesia

From Hawaii to French Polynesia

We arrived in Baie de Taihoae on Nuku Hiva, in the Marquesas Islands of French Polynesia, 31 days and 2,550 nm after leaving Honolulu (trip log map). We had stopped at Palmyra Atoll and Fanning Islands for 11 days, for a total of 20 days at sea. We left Honolulu with 2,350 gallons of diesel…
