On Friday, March 14, starting at 0100 and lasting until 0500, there had been a full moon eclipse. Had we stayed up and the clouds cooperated, we probably could have seen it from here. But chose not to. When we awoke, the eclipse was fully over and the moon was shining like a spotlight.
Dawn:
Thursday, March 13 — In the early morning, before dawn began, the full moon looked like a spotlight
The sunrise was beautiful
Wednesday, March 12, 2025 — We were up again early to get the boat ready to go to sea. A storm was coming in the next few days. As much as we liked this place, we’d had to make a decision between staying here longer than planned or leaving sooner than planned. We opted for sooner. We picked an anchorage ten hours away so we could do a day run.
We quickly got the dinghy up and all the loose things stowed. As soon as dawn broke (shortly before 0700), Eric turned on the engine. The stabilizers didn’t turn on. Eric troubleshooted and determined that the servo controller (main computer) was getting power.
Our new friends also decided to move on for the storm. Here they were leaving the anchorage as the sun rose.
Wednesday, March 5 — The weather forecast had changed for the worse, so we needed to either leave Jamaica sooner than planned or stay longer than planned. We opted for sooner, which meant we needed to get serious about boat projects and sightseeing.
After our morning routine of schoolwork and boat chores, Eric ran a bunch of tests to verify how the boat’s systems operate. After the voltage regulator problem he wanted to parallel in each of the battery banks to the house bank to make sure they each worked, which they did. He verified that the main engine shuts down without voltage from the house bank of batteries. He verified that if he shut the engine bank off, then shut off house bank, then the engine wouldn’t shut off. This confirmed his suspicion that the Seafire system was getting power from the engine bank in order to shut off the engine.
Ed had come by that morning and was being pushy about escorting us on a sightseeing trip. Knowing that we were running out of time, at 1500, we took him up on the offer. He said he was taking us to the Frenchman’s Cove and the Blue Lagoon. Ed walked us over to the gas station between the two main roads in town and we caught a taxi.
The taxi took the road that paralleled East Harbor. We headed southeast for about five miles. Shortly beyond East Harbor, the waterfront became all privately owned property. The buildings along the shore were mostly homes, with a few hotels, and was an interesting mix of old, new, small, large, low-end and high end.
Tuesday, February 25, continued… After bypassing the battery protect device, and having Zeus set to 60% max load (~100 amps at cruising RPM), it was time to do some testing. First, Eric ensured switching to emergency power would work. He turned off the house bank via the BMS (simulating what had happened earlier), and then initiated emergency power by paralleling in another battery bank. It worked. Then Eric simulated being on a passage. He turned the main engine on, revved up to 1750 RPMs, and had all underway systems on. He watched the power readings like a hawk. This is where it got a bit weird. Every 400 seconds the Zeus restarted itself. Charging went to zero; but it had restart delay, so it took about 30 seconds to start charging again.
In general, we use about 60 amps underway, and this was actually enough charging for us to do the passage. However, watching the Zeus reset over and over made Eric nervous. He ran the engine for almost two hours, checking and watching. Eric had to made a decision: try to make it to Jamaica with a questionable alternator regulator, or re-check-in to Panama and try to troubleshoot more. Since the weather windows here were few and far between, he did not want to give up this window.
Now that we were certain that emergency power via paralleling another battery bank, we knew we could utilize the generator and the secondary alternator to charge the batteries. If there was a problem with the Zeus again, Eric would switch to emergency power, restart the LiFePo battery system, and run the generator to continue operating Kosmos via the LiFePo battery bank. He wanted to keep the secondary alternator in reserve and the other battery banks in reserve, as well. He also wired the ignition trigger voltage to a breaker in the pilot house, so if things started to go awry with Zeus, he could shut it down easily.
Keith and Christi helped with the testing/rewiring. Once Eric was done, Keith did archery with his friends. We had dinner in the marina restaurant.
On Wednesday, we didn’t need to wake up until 0500 to do the last minute things before going to sea since Kosmos was still mostly ready to go. Eric was feeling confident that that if there was another issue with the Zeus, he could turn it off via the switch that he’d wired up yesterday.
We untied at about 0600. This morning was much gloomier than yesterday, which felt ominous. We passed through the channel from the marina into the bay at low RPM’s, just as we had yesterday. When we were far enough into the bay that we felt like we were safe from any potential obstacles, Eric revved up the engine. All worked fine.
We exited Limon Bay via the east entrance. The big ships only use the west entrance, so we’d anticipated less traffic. Here were two ships passing in the west entrance.
