Thanks guys for your help. Having just returned, I can confirm that I found another worthwile option.
At Tanjong Beach, Sentosa there is a new operation with 10 new Surftech boards including some Lairds and 4 Bark boards. Two 14' and a couple of 12'6. Good condition with QB adjustables.
Isabelle, the owner, is helpful, accomadating and charming, she opened til late so that we could paddle after work and came with us on a mini tour of the coast up Sentosa.
The scenery is different from what we experience here, but it's good to see another perspective, with Sentosa's manmade exorborance on one side and one of the Worlds busiest shipping channels on the other.
But the water is 29 degrees and I'd rather paddle any day than go for a run in an airconditioned hotel gym.
Check it out if you are over there at any time, and help to grow the sport in the area and spread some SUP spirit.
