French Navy’s deep-sea ops accidentally reveal shipwreck from 1500s
A French Navy underwater drone operating near Saint-Tropez has discovered the deepest shipwreck ever found in French territorial waters, resting at a depth of 2,567 meters (8,200 feet). The wreck, provisionally named Camarat 4, is a remarkably well-preserved 16th-century Italian merchant vessel from the Renaissance period. Measuring about 30 meters long and 7 meters wide, the ship was initially detected by sonar and later explored with remotely operated vehicles (ROVs), revealing an intact cargo including nearly 200 Ligurian ceramic jugs, iron bars, artillery pieces, an anchor, and yellow-glazed plates. Despite some contamination from modern debris like plastic bottles and fishing nets, the archaeological significance remains exceptional. The ship likely originated from Liguria, northern Italy, as indicated by the ceramic artifacts bearing mid-16th-century Ligurian motifs and the vessel’s design consistent with Ligurian or Genoese merchant ships. Such vessels were integral to Italy’s Renaissance-era

ACEL Power, a Canadian leader in intelligent electric propulsion systems, has partnered with Madrid-based boat builder Vector Náutico to launch a new electric boat line called MOLA-e. Designed for coastal and inland cruising, the boats measure 5.99 meters in length and come in two configurations: a 50HP model with a 32 kWh lithium iron phosphate (LFP) battery and a 75HP model with a 43 kWh LFP battery. These batteries offer high energy density, extended lifecycle, and enhanced thermal stability, enabling zero-emission propulsion without sacrificing performance. The MOLA-e line aims to combine luxury yacht design with the accessibility of a day cruiser, featuring optimized hull geometry for improved range and handling, as well as wide swim platforms for easy water access. The first units are expected to debut in mid-2025, with sea trials and showcase events planned across Spain. Pricing and customization details will be released closer to the launch. Both companies emphasize sustainability and reliability, positioning

China has launched the Meng Xiang, its first domestically designed and built deep-ocean drilling vessel, capable of drilling up to 11 kilometers (6.8 miles) beneath the ocean floor. Officially commissioned in November 2024 in Guangzhou, the vessel is set to begin drilling operations in the South China Sea later in 2025, continuing through 2035. The Meng Xiang aims to advance understanding of the Earth’s deep interior, particularly the boundary between the crust and mantle known as the Mohorovičić discontinuity (Moho), which has previously been studied mainly through indirect methods like seismology and volcanic mineral analysis. The Meng Xiang is China’s largest scientific research vessel, measuring nearly 180 meters in length and displacing 42,600 tonnes. It features a first-of-its-kind hydraulic lifting rig capable of both oil and gas exploration and scientific core sampling, supporting four drilling modes and three coring methods to accommodate diverse geological conditions. The ship can operate unassisted for 120 days, has a range of 15,000 nautical miles, and houses nine advanced laboratories covering fields such as geology, geochemistry, microbiology, and ocean science. Additionally, it includes the world’s first automated shipborne core sample storage system and is engineered to withstand super typhoons, ensuring safe operation in extreme sea conditions. This vessel represents a significant step forward in marine science and technology, offering unprecedented opportunities to study the Earth’s deep ocean and interior.
