To answer your questions about the ferry boat from Sumbawa to Sumba, I am not sure. I will ask my brother in Sumba and let you know later. In Tarimbang, there is a Marthen's Homestay, owned by a friend of mine. His place is beautiful. There are few huts, individual huts from Bamboo and grass roof, very traditional Sumba. He is very accomodating with his guest. He has a Jeep to pick up his guest and drop them to the airport, stuff like that. Email me if you need more info and gladly give you his phone number. You will love it there. By the way the Homestay will provide 3 meal a day I believe. Of course there would be lots of rice as their main staple and veggies, fish or meat and fruits. Lots of coconuts, papayas and bananas. Email me for his phone number. I rather not posting his phone here. Sumbagirl2005@yahoo.com. Have fun. Jade.
