Since Raiatea, shuttles are frequent but not always regular, and carriers'names and schedules change all the time.
From Bora Bora it is possible to take the famous Maupiti Express 2, which, as its name indicates, also travels to the island of Maupiti. However, it may not work during your passage (cessation of activity on November 4, 2011 until further order).
From the other islands of the Archipelago, the info is given in the section "Transport" of Huahine or Papeete.
From Raiatea, several taxi boats and shuttles… not a large world can give the scheduled timetables. A priori, departures from Raiatea from the dock to the Champion from Monday to Friday at 9 a. m. and 15 p. m., Saturday at 9 p. m., for a return to p. m. and p. m. Count 650 PSC per person one way.
