The last time I went on an kayak expedition was in 2007. Im not including the trips I've made to the Merlion because, thats not really considered a sea journey.
I decided to join the SAFYC Changi to East Coast kayaking trip organised by Asian Detours to give myself a rough idea of how I would fair in next week's round Ubin paddle. A return trip is approximately 20km, which is the farthest I have ever paddled in a day.
It took me about 1.5hrs to paddle 10km so I think the round Ubin trip will last at least 4 hours including time for lunch and rest.
Rest of the pics are here
