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 Fishermans Knot is a simple but effective way to join two lengths of rope together. The knot is more secure than a sheet bend under light load as you can tighten the overhand knots around the main lines which prevent the knot from coming undone before load is put on the lines. The Fishermans knot is preferred to tying a sheet bend when the rope diameters are the same. If you are going to have constant high levels of load on the joined lines the Fishermans Knot will become hard to untie, if you are join ropes which will stay under constant load are Sheet Bend will work better. Learning how to tie a fisherman knot is easy, most people already know how to tie a overhand knot, the Fishermans knot is tied by combining two overhand knots. Click the link below to learn how to tie a overhand knot. https://youtu.be/5z3BR2vCTcc Some sailing use cases for the Fishermans Knot include :- * Joining Jib sheets together to make them continuous * Joining Spinnaker sheets together to make them continuous. * Joining rope that have broken together in an emergency * Making a short rope longer Thanks for visiting the Bottom Up Boats channel, we hope you enjoyed this short video and you learnt a new skill that will help you with your cruising or racing.
