Koh Samui to Krabi From the Gulf to the Andaman in one day.
The short answer: take Lomprayah's catamaran and coach. Boats leave Nathon pier at 08:30 and 11:45, cross to the mainland, and the coach reaches Krabi about four hours later, for 1,100 baht, or 1,250 baht with a drop at your hotel in Ao Nang or Krabi Town. Bangkok Airways also flies once a day in about 50 minutes, but it costs several times more.
Below: every boat-and-bus ticket side by side, which pier on Samui they leave from, and how to get to Ao Nang or Railay at the other end.

Which one should you pick?
Take Lomprayah if you want the quickest boat-and-bus trip. Pay the extra 150 baht for the hotel drop if you are staying in Ao Nang or Krabi Town.
Take Phantip or Seatran if you want to spend less. These end at Krabi Bus Terminal unless you buy the Ao Nang drop, and the car ferries are slower than the catamaran.
Fly only if the time matters more than the money: there is one nonstop flight a day, and it fills in the high season.
How the trip works
There is no boat from Samui to Krabi: they are on opposite coasts. Every ticket crosses to the mainland pier at Donsak near Surat Thani, about 45 minutes on Lomprayah's catamaran or 1.5 hours on the car ferries, and a bus or van then drives about three hours across the peninsula to Krabi.
On Samui, most boats leave from Nathon on the west coast. Raja Ferry uses Lipa Noi, and Lomlahkkhirin's speedboat leaves from Pralarn pier in Maenam on the north coast. Check the pier on your ticket; one traveller on 12Go went to the wrong one and missed the boat.
Arriving in Krabi
Tickets to "Krabi" usually end at Krabi Bus Terminal or the operator's office in town. From there, songthaews and taxis go to Ao Nang. For less hassle, buy a ticket with a drop at your hotel.
Railay has no road. Go to Ao Nang and take a longtail boat across, or book Lomprayah's or Lomlahkkhirin's ticket through to Railay. See where to stay in Krabi.
The other way
From Krabi to Samui the same companies run the trip in reverse; Lomprayah, for example, runs its coach and catamaran twice a day. Check the times for your date on 12Go.
