The sail is attached in the lower part to 4 sewn loops, corresponding thin rope is not included. The four thousandths must be fixed in the ship according to location. The sail first appeared quite small, but provides adequate ventilation when turning weak winds. The stronger the wind, the smaller one would want the sail.
Function excellent. Unfortunately, the fabric material is not UV resistant. The white material breaks down after only one season in the tropics. The yellow fabric is not. It is probably the case that colored fabrics are more UV-resistant than white ones.
