'I got an Saturn inflatable kayak last spring as a companion of my trip. Since then, Saturn traveled everywhere with me, from a wild river in Hokkaido (northernmost island of Japan) to tropical ocean islands of Maldives (island nation in the Indian ocean located at about 700 km southwest of Sri Lanka). It gave me great pleasures that had not been experienced before getting it. There were several reasons why I chose Saturn kayak as my companion boat. The first was its portability. The total weight of Saturn kayak including paddles and a pump is lighter than free baggage allowance of any airline company. Saturn kayak can be packed in a suitcase of 70x50x35cm (I cut each paddle into two peaces), which is convenient for manual transportation. The second was the toughness of PK375. It was not punctured by hidden rocks in the rapid stream and coral reefs in the tropical ocean. The third was the stability and controllability of Saturn kayak. It was stable enough for watching a wild life from the river and rapid enough for hopping island to island in the tropical ocean. In conclusion, I am very satisfied with Saturn kayak irrespective of its low price. A photo taken at Biyadhoo island, Maldives, is attached.' Best wishes, T. Ichikawa, Sapporo, Japan
