Saturday, March 8 — We untied from the dock in Port Antonio at about 1130. As soon as we left the bay and got out into the open ocean, the swells were about 3-feet at 6-seconds, directly on our nose. The wind was about 10-knots, creating about 1-foot wind waves, also directly on the nose. We were hobby-horsing like crazy. Eric immediately got sick. Keith initially felt okay, but once he started looking at his screen, it didn’t take long before he was sick, too.
Wind and sea conditions stayed the same all of Saturday, and Eric and Keith were sick all of Saturday. During the day, it was sunny with scattered clouds. At night, the 3/4 full moon shone so brightly it was like a spotlight, making the stars barely visible. However, after the moon set, the stars were vibrant.
Monday, March 3 — After being in the jungle at Shelter Bay marina for over a month, we were used to waking up to a cacophony of chirping birds. This morning, there were chirping birds, but they were overshadowed by crowing roosters and car traffic. The air smelled distinctly of smoke. Yup, we were back in a city.
We were sad to report that it never rained. At 0900, Eric was at the marina office to request that the water be turned on so we could rinse the boat. While rinsing the boat had certainly helped with the salt accumulation, in order to eliminate it, we needed to hand scrub. We did some scrubbing in easily accessible spots, but we’d have to go back to scrub the rest of the boat later. We also noted that the marina’s pipes have a significant leak — no wonder they only turn them water on upon request.
This morning, we found out what the warning that the locals were too nice meant. At several different points in time, we were greeted by locals offering assorted services. And when we said no to one service, they had another and another and another service that they offered. They each kept pushing until they found something we’d buy. One roped us into buying locally grown coffee, another a jerk spice mix and jerk sauce. Both promised to procure “the best” and return later with their respective products. And in all fairness, both products were indeed great, though we suspect the markup for the delivery was huge.
Sunday, March 2 — Tonight was a rare astronomical event — a seven planet alignment, with several of the plants visible to the naked eye. But sadly, the seas were too uncomfortable for us to even consider sitting outside to see it.
By midnight, we could see lights from southern Jamaica in the distance. By dawn, we were close enough to be in the shelter of the island and the waves became a little smaller. We could also smell smoke – not an unpleasant smoke, like a fire, but like smoking food.
Shortly after dawn, we rounded the western corner of the island. Our change in direction meant we went from head seas to beam seas. Eric’s seasickness instantly vanished. As we trekked north, we ran close to shore. From what we could see, Jamaica was mountainous and lush.
It only took a couple of hours to go from the southern side of the island to Port Antonio, located on the north-eastern side of the island. We turned into a bay named East Harbor, then immediately turned into a channel between the tip of the mainland peninsula and Navy Island that led into a bay called West Harbor.

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.
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.
