Balancing alternator outputs

Balancing alternator outputs

In our charging configuration, we parallel the house and start alternators to charge the house battery bank. Each alternator has its own individual Balmar Max Charge MC-624 regulator and we’ve been asked a few times if we balance the outputs ...

Fuel bugs

Fuel bugs

As we describe in Dirona fuel manifold, we choose to explicitly pump fuel from the appropriate bulk tank to the supply tank rather than gravity feed. This is a slightly more manual operating mode but has some advantages that we really like. The ...

Hot Rodding the Mastervolt Inverter

Hot Rodding the Mastervolt Inverter

Our Mastervolt MassCombi 24/4000-100 120V inverter works well and we generally like it but it has always seemed to go into thermal shutdown earlier than it should. The inverter is particularly vulnerable to thermal cut out when it’s more ...

Changing the Hydraulic Actuator

Changing the Hydraulic Actuator

Stabilizers are used on ocean-going vessels to remove the discomfort of ocean swell. Generically they come in two broad forms, passive and active. Passive stabilizers are the metal fins that you might have seen hanging from outriggers on fishing ...

Oil Change at Sea

Oil Change at Sea

Earlier this week, we brought the boat up on the wing engine and shut down the main engine to change the oil. Normally we’d never do this, even though the chance of a problem is small, because in the unlikely event that a problem does ...

To Change or Not to Change? That is the Question.

To Change or Not to Change? That is the Question.

Oil changes at sea get pretty close to a universal response from boaters I know. Everyone says loudly “DON’T DO IT.”  The risk of something going wrong when hundreds, if not a thousand miles, from shore is simply too high. And, ...

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 ...

Boat projects

We travelled directly from Rodrigues to Reunion, skipping Mauritius, mainly to spend more time enjoying Reunion’s incredible natural beauty. But we’ve also been taking advantage of being on a little less of a tight schedule to ...

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 ...

Diesel engine underload

Diesel engine underload

We’ll be running our main engine at fairly low load for several weeks while we cross the Indian Ocean. Since this likely is below the manufacturer’s recommended range, we’ve been asked if we’re concerned about ...

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 ...

Maintenance log

Maintenance log

On our previous boat, we were (just barely) able to remember when all mechanical systems needed service as the hours mounted and time passed. But that system broke down when we got the current boat. There are far more systems, many of the ...
