The two options

Option Duration Indicative price Good to know
Direct speedboat (Satun Pakbara Speed Boat Club) About 5h, departs around 8:30am Very variable by source: one listing shows about US$82 in the Koh Lipe - Phuket direction About 7 departures a week depending on season; no cars
Road to Pak Bara + speedboat Boat about 1h30; road to check Boat 550 to 1,100 baht depending on operator Departures from Pak Bara around 9:30am, last around 1:30pm per one source

I found no reliable source on the Phuket - Pak Bara road leg (duration and price): check before booking.

When to go

The boat season follows the Andaman Sea: from November to April the sea is calm. In the monsoon some links are reduced or cancelled. See the best time to visit Phuket.
