Welcome to the forum Craigfishboy and congratulations re the
new boat. I've cleared in and out of Singapore from Raffles Marina as well as at "The Sisters" in Singapore straits but that might have changed in recent times. There was some trouble a year or two ago where a
catamaran with guests on board entered Singapore to commit a crime without clearing in or out and things got a lot less accommodating at immigration and
customs after that.
