Hello Max,
The last time I checked, there was an authentic Malay Junk in Langkawi, west coast Malaysian island near Thai border. It was built on an island near Terranganu, (East Coast of Malaysia) and is owned by Christophe Swarboda. It is his second Malay Junk. He had a smaller one built before this one, that he and his family circumnavigated in. No idea where that first one is.
There is an old junk in Stanley Harbour Hong Kong, that needs some work, and that seems to be the only junk in HK that isn't a Tourist boat.
Philippines have no junks only bankas, very occasionally with crab claw sail, and the 'junks' in Indonesia are gaff rigged, and once again, dying out. Bali had crab claw sails on their fishing bankas, and there were a a lot of them on the NE coast. Looked like a regatta. We went out with one of the fishermen and it fair flew along. good haul of skipjack tuna too!
Rene and I will be back in Malaysia mid November until late February. Crib is currently in East Malaysia and we hope to be heading for Langkawi. Do get in touch if you are likely to be nearby and would like to meet up with us.
Lesley and René
