I did Singapore
last year on an Athena 38. Boat had many problems (previously written about) and instead of doing Singapore-Bali-Darwin-Cairns-Brisbane, I ended up doing Singapore-KotaKinabalu-Ambon-Cairns. Prior to that, I had taken the boat down from LAngKawi to Singapore. I didn't find any piracy
problems. I did have weather
problems all the way across the top of Oz and down the other side - but that was weather
timing: trip should have started a month later!
I had not arranged a crusing permit
for Indonesia: not a difficult thing to do but I had never intended going into Indo anyway. So - when I had to divert into Ambon, I was a tad concerned about the lack of this bit of paper. However, on explaining to them that I was not "cruising" but merely passing through, and had had to stop for electro/mechanical problems, they were very reasonable and helpful.
