Silversonic passengers and crew recently enjoyed an amazing experience, when an Ornate Eagle Ray (Aetomylaeus vespertilio) was spotted swimming around "Barracuda Bommie", one of Quicksilver's remote dive sites on the Agincourt reefs. This gentle giant (one of the few species of eagle ray without a stinging barb) measured nearly 2.5m across the wings, and total length over 5m. The Ornate Eagle Ray is well named, as the patterns across the dorsal surface are exquisite, consisting of a mosaic of stripes and spots. Shane Down, Crew of Silversonic said, "The last time we saw an Ornate Eagle Ray was 3 years ago on Silversonic. It was an unbelievable sight and this new encounter may be the first one in Northern Australia that has been captured on video. It is a very rare and unique encounter -- like winning lotto underwater." Doug Baird, Quicksilver Cruises Environment and Compliance Manager said, "The species is not well known, and this is only the second one we have seen at one of our reef sites and there are only a few records from the northern parts of Australia (the last time an ornate eagle ray was spotted was in April 2008). They only produce 4-6 live young, making them highly vulnerable. Eagle rays live in the open ocean rather than at the bottom of the sea. They eat snails, mussels and crustaceans, crushing their shells with their extremely hard teeth. They are excellent swimmers and are able to jump several metres above the surface. They are classified as Endangered".

For centuries sailors have navigated their way across the oceans by celestial navigation or nautical astronomy - using a sextant with the sun, moon, planets, and stars. For the modern sailor, it is essential when crossing oceans as back up to the modern and much relied upon electronic navigation. If you are curious about how to use a sextant or have taken the RYA Yachtmaster or Ocean Theory courses, or are even self-taught, our celestial sailing weekends are ideal offering both an introduction and a refresher. All are welcome. A big advantage is that you learn in a small group, under the supervision of an expert instructor. The weekends involve sailing along the south side of the Isle of Wight and back up through the Needles. A beautiful area to sail whilst offering ample opportunity to practice using the sextant.
