Hi Sheen,

you are correct, there are many cargo boats from both JB and Singapore into Batam. But Batan is not a recognised entry point for vehicles into Indonesia.

Indosnesia is one of those countries where rules are difficult to tie down. Physically it is probably possible to find a cargo ship willing to take you into Batam, but then you have to get your bike past the Batam authorities, then find a ship to take you further on into Indonesia.

I lived in Indosnesi for 10 years, and can honestly say "anything" is possible, but unless you can find out before trying that it can work that way, I would strongly suggest the tried and tested route of Penang to Belawan.

On the other hand RTW is suppose to be an adventure.... so trying something is part of the trip. A lot depends on your flexibility (time) and the amount of hassle you are willing to put up with, during my time in Indoensia there was nothing I tried that eventually could not be done, but a 22 my ability to take hassle was better than now.

If I can help with specifics, let me know, I'm in Sinapore during the week and Kl at weekends. Another route that does work (but is more hassle) is Melaka to Pekan Baru in Riau. Several have done it on this site, but several have tried and given up. A lot depends on the mood of the ferry operator and the customs guys in Indonesia.

good luck.
