Trystern SG i think you can rent sit-on-top kayaks without star certification. check out Paddle Lodge at MacRitchie Reservoir. http://www.scf.org.sg/Facilities/PLDetails.html for info on star certification, other than PA Sea Sports Club, you can also obtain it under Singapore Canoe Federation, who regulates all canoe/kayak related activities in singapore. info in the link below. http://www.hydrotribe.com/forum/viewtopic.php?t=31
