Sailboat Wanted Indonesia
Did not sail the route but did charter a 100'' dive boat for 2 weeks and covered almost the same area. Started near Komodo and went to sumbawa and flores. Stayed south because north near Maluccas is dangerous. The entire time I wished I was cruising on my 49''Morgan.
Did not see one cruiser. There is no infrastructure, no marinas and little security. But it is gorgeous. One of the best diving spots in the world.
As for buying a boat, I think you would be better off looking in Singapore or Malaysia.
I go to Bali but do not remember seeing any cruising. I think it is because of security concerns when offshore. Saw a number of native boats but not very seaworthy.
Waters in Thailand are safer.
I have a profile and boat pictures in the personal page section
