The yellow stingray (Urobatis jamaicensis) is a species of stingray in the family Urotrygonidae, found in the tropical western Atlantic Ocean from North Carolina to Trinidad. This bottom-dwelling species inhabits sandy, muddy, or seagrass bottoms in shallow inshore waters, commonly near coral reefs. Reaching no more than 36 cm (14 in) across, the yellow stingray has a round pectoral fin disc and a short tail with a well-developed caudal fin. It has a highly variable but distinctive dorsal color pattern consisting of either light-on-dark or dark-on-light reticulations forming spots and blotches, and can rapidly change the tonality of this coloration to improve its camouflage. Relatively sedentary during the day, the yellow stingray feeds on small invertebrates and bony fishes. When hunting it may undulate its disc to uncover buried prey, or lift the front of its disc to form a "cave" attractive to shelter-seeking organisms. This species is aplacental viviparous, meaning that the developing embryos are sustained initially by yolk and later by histotroph ("uterine milk"). Females bear two litters of up to seven young per year in seagrass, following a gestation period of 5–6 months. Though innocuous towards humans, the yellow stingray can inflict a painful injury with its venomous tail spine. This species is taken as bycatch by commercial fisheries and collected for the aquarium trade; it may also be negatively affected by habitat degradation. Nevertheless, it remains common and widespread, which has led the International Union for Conservation of Nature (IUCN) to list it under Least Concern.

The full review of the M.9, the prototype of the M.10, is out! You can order it here: https://www.multihulls-world.com/review/motor/m9-m10-s-prototype-a-100-electric-powercat or read it for free if you are a Multihulls World subscriber. The M9 electric powercat - built in St Malo, Brittany, then assembled and completed in Caen, on France’s Channel coast - made its public debut in the Mediterranean. But what’s so special about this new model? Its two-sided solar-powered wings, that unfold when under way: the photovoltaic cells facing the sea thus capture the sun’s reflection from the surface of the water. In total, the solar installation is capable of producing 6 kWp, a considerable figure for a catamaran just over 30 feet in length. At 6 knots, range is unlimited - during the day, weather permitting. The second remarkable technological innovation is the car-like control interface. The on-board computer controls all the settings and manages the virtual anchor system: the motors are connected to the GPS position to “hold” the boat without the need to drop an anchor. A third point worthy of note: when folded, the solar wings, together with removable glass panels and canvas sections, transform the central part of the powercat into an enclosed space measuring 130 square feet (12 m²), called the deck cabin. The table in the saloon can be lowered, and cushions added, to create a double 4’7” (1.4 m) berth. The interior is cozy and include a galley. In the hulls, there are two cabins and a heads compartment. The foredeck is fitted with a trampoline, which is lighter than a rigid deck. At the stern, the yard has designed two bathing platforms.
