Come and JOIN the ADVENTURES - https://thejunk.com/liveaboard-schedules/ Plankton are an incredibly diverse group of organisms that inhabit the world's oceans, lakes, and rivers. They are classified into two main categories: phytoplankton, which are microscopic plants, and zooplankton, which are tiny animals. Characteristics of Plankton Drifting Nature: Plankton are primarily characterized by their inability to swim against currents. Instead, they drift with the water flow, which means their distribution is largely influenced by oceanic and atmospheric currents. This drifting lifestyle allows them to occupy various ecological niches in both freshwater and marine environments. Size and Diversity: Plankton vary dramatically in size, ranging from tiny bacteria (nanoplankton) to larger organisms like jellyfish (macroplankton). This diversity also extends to their biological classifications, including single-celled organisms like diatoms and dinoflagellates among phytoplankton, and small crustaceans such as copepods among zooplankton. Ecological Importance: Plankton play a crucial role in aquatic ecosystems. Phytoplankton are primary producers, converting sunlight into energy through photosynthesis and forming the base of the food web. Zooplankton feed on phytoplankton and serve as a food source for larger marine animals, including fish and whales.

It was more like dodgem cars than yacht racing at the first mark of the Craobh to Oban passage race WHYW 2023. The team on the J109 GTR got themselves out of a tight spot by forcing the boat on the port lay line to duck them about 7 or 8 boat lengths from mark. They were then caught out by the fast flowing tide which pushed them well below the lay line. While the racing was tight everyone was playing fair either tacking or gybing there way out of the possible pile up while keeping clear. This is until the last boat on in the line on the port layline came steaming with no overlap at the thee boat lengths to shove it in at the top mark. The team on GTR decided it was better to play in safe on a long race, rounding up to avoid a collision. Sadly the boat which was in another class did not do circles choose instead to sail on as if nothing had happened. There was lots of tight racing across the whole week which made for a great regatta in the Scottish Highlands. The team at Bottom Up Boat hope you are enjoying the action from WHYW 2023.
