Pemba to Tanga

I have no desire to double back to Zanzibar or Dar Es Salaam so i take the weekly ferry from Wete (on Pemba)to Tanga (on the Mainland). It costs Tsh30,000 for non-residents, departs promptly at 9am and takes five hours. There is a simple canteen on board selling snacks (including quality samosas). There are immigration checks and customs to clear both in Wete and Tanga.
