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.

El gran problema de navegar a vela. No podemos navegar justamente con la proa al viento. En nuestros barcos modernos, como mucho podremos tener un ángulo mínimo de nuestra proa con el viento de unos 45 grados. Y no se te ocurra apostar, si eres un cenizo como yo, seguro que el sitio donde quieres ir hoy está justo en tu proa. Y cuando vuelvas rolará el viento. Para ello, deberás virar por avante o virar a secas. Pasarás el viento por la proa, de la amura de una banda a la otra amura. Pero ¿Sabes hacer bien esta maniobra? Ven a aprender a tu masterclass Sailing Txemacapitan. Si te ha gustado el vídeo 𝐒𝐮𝐬𝐜𝐫í𝐛𝐞𝐭𝐞 𝐚𝐥 𝐜𝐚𝐧𝐚𝐥 👍 Así nos ayudas a generar más contenido para ti... los amantes de la navegación y del mar.
