ARCO Zeus Endangering Critical Failure

Note: Christi normally writes the blog posts, however, since this is a boat technical post, Eric has authored this one.

Tuesday, February 25: We rolled out of bed at 0400 and did all the last minute things we always do before going to sea. Our first inkling that something could be wrong came at about 0530, when I turned on the main engine to warm it up. Before we get into the details, here is some important background information:

While underway, electricity to charge the batteries for Kosmos is made from an alternator on the main engine. It is an important system, and having electricity from the main engine allows us to run all the boats systems without running the generator. While underway, the boat uses quite a bit of electricity for air circulation, navigation/radar, and all the usual loads (refrigeration, freezer, lights, Internet etc.).

The main engine alternator is externally regulated by a product from ARCO called Zeus. External regulation is a general practice for interfacing with Lithium Iron Phosphate (LiFePo) batteries, which was part of the upgrades made to Kosmos after we got back from the Sea of Cortez. Zeus has an app and can connect via Bluetooth for configuration and monitoring. Mainly, it can reduce the load on the alternator ensuring it does not overheat. The Zeus box has several sensor wires for temperature, RPM, voltage, ignition, regulator control, etc.

Getting Ready to Depart Panama

Sunrise on Sunday February 23

When we arrived in Shelter Bay Marina on January 19th, we’d expected to move on in the first few days of February. However, the weather has been uncooperative, so we’ve stayed about 3-weeks longer than anticipated. We were happy to see that the weather was finally cooperating and we could leave on Tuesday in the very early morning.

The majority of Sunday was spent getting Kosmos ready to go to sea. Since we’d been at Shelter Bay so long, we’d unpacked a lot of items from the assorted deep, difficult to access storage spaces. Getting it all put away was a Jenga game, as everything needed to be carefully packed so it wouldn’t shift when the boat was rocking. 

Eric also led a kids’ D & D session. In the evening, Christi and Eric went for a walk in the jungle, following the road to Gatun Bridge for about 3/4 mile, until we got to a small bridge over a stream. Unfortunately, there was no walkway for part of the bridge, and being a blind curve, we decided it best to not walk in the road. We turned around and went back to the marina. The expanse between the T-intersection and the bridge where we turned around was mostly jungle.

More Exploring the Ruins of Ft. Sherman

On Saturday, February 22, the sun was about to peek over the horizon when the giant black cloud to the left blew in front of it and blocked the sunrise completely. 

This morning, the water was still not working. The dockmaster assured us that this time, he was being more proactive. He was making arrangements for water trucks and working on a strategy on how to get the pressure up enough to ensure that the water made it to the boats. However, the plan didn’t need to come to fruition because water was restored  in the mid-afternoon.

In the afternoon, Eric led another kids D & D session. Afterwards, the kids went to the pool and Eric joined them. 

While they were playing, Christi decided to explore more of the ruins that we’d seen along the road to Gatun Bridge. We’ve already mentioned that the marina was directly northwest of what had been the military air strip, which was now used as a Panamanian Coast Guard base. The majority of the Coast Guard Base was set back from the road, and there were several ruins along the road that were not currently utilized by the Coast Guard.  

Where the road turned south, Christi spotted some birds walking around. What made the species noteworthy were the red, beady eyes, which made them look a little zombie-esque. We’d seen some of them at the beach on Wednesday, and as they walked amongst the trash near the derelict buildings, they’d only added to the creepy feeling of the beach that day.

Breakfast at Rume and Lying Low at Shelter Bay Marina

Sunrise on Thursday February 20

The day that we’d gotten pizza and gelato, we’d stopped by the three bakeries to see what they stocked. We’d gotten a loaf of bread from the one called Rume. It turned out to be one of the best sourdoughs we’d ever had. We’d also noticed that they opened at 0730 for breakfast. 

Since the car didn’t have to be returned until 0930, that left us just enough time to get breakfast at Rume. The food was great, and we were thrilled to be able to get out of the marina one more time.

Portobelo, Colon Province, Colombia

Thanks to cloud cover, the sun itself was not visible on Wednesday, February 19, but it was still a colorful sunrise.

We decided to keep the car for another day to go to the town of Portobelo, which was about 80 km (50 miles) away from the marina. Portobelo was a small town with a nice bay and protected anchorage that was popular with the cruisers. It was a pivotal part of Spain’s colonial rule, so it was historically significant. Since we wouldn’t be going to Portobelo by boat, we thought it would be fun to go by car. 

On our way out of Ft. Sherman, we decided to make a quick stop at the public beach. Since we’d driven by it so many times, we felt like we should at least stop and see it up close. It was a man-made beach, south of the Coast Guard base, along the road to the bridge. It was usually packed on the weekends. The US military had put in, and it was lined with more of the same housing structures that we’d seen at the loop… except these were in much worse shape. 

We parked in the small parking lot and ventured in. Maybe it was the gloomy weather, but the beach felt sad. There were dilapidated buildings, sunken ships and a lot of trash strewn around. Someone had put up a series of palapas, but most of them had fallen apart into hunks of debris that added to the trash.
