The tell tale is a product that has not evolved, not been updated and not been improved since they were designed despite major flaws, until now. Sea Sure’s new “FLO” tell tales are shaped in an aerofoiled tear drop and manufactured from glass filled nylon. The rounded top surface to the tear drop allows the wool to stand 6mm off the sail so that the wool never gets stuck to sail when it is wet. This means that whether it is raining, or you have just recovered from a capsize, you will be able to carry on sailing and get the feedback you need from the sail straight away. FLO has been designed by former Americas cup designer and current coach to the British Olympic Team Derek Clark. FLO has been tested and used around the world by world champions.
