Our progress towards Trinidad continues, but not without a minor setback. Last night, we encountered some strange engine vibrations. The intensity fluctuated, sometimes barely noticeable and other times more pronounced. This had us wondering if they'd been present all along and we just hadn't noticed. However, around 11 pm, the vibrations became strong enough to warrant taking action. We shut down the engines, folded the propellers, and restarted everything. After some testing, it seemed the starboard engine was the culprit, exhibiting slightly worse vibrations. The reason? The mystery remains unsolved. My best guess is seaweed. There are large clumps of seaweed floating around, and it's possible some gets caught on the blades of the props causing the vibration and dislodged when the propellers fold. We'll know for sure once daylight allows a proper look overboard. This whole ordeal served as a reminder that even the best-maintained boats can encounter unexpected issues...
