Speed buys beach time. The crossing from Thong Krut is over in a quarter of an hour, so a speedboat day spends its hours ashore and on the reef rather than looking at the horizon. Three shared speedboat trips go to the pigs, and they are not interchangeable.
The lowest adult price on the site, checked at THB 1,450 with children at THB 1,250. Pickup 08:30 to 09:00, boat out of Thong Krut at 10:00, pigs, reef, lunch, home in the afternoon. If you have no strong preference, start here.
Same islands, later clock. Pickup runs 13:00 to 14:30, you snorkel while the light is still good, meet the pigs as the beach empties and come back with the sun going down behind Samui. THB 1,495 per adult, THB 1,295 per child, and the most reviewed speedboat on the site.
Crosses to the Khanom coast first to look for the pink dolphins, then returns for the reef and the pigs. The earliest pickup of the three, from 07:40, THB 1,795 per adult and THB 1,595 per child. A longer day and the only shared tour that shows you two things most visitors never see.
You sit in rows close to the water. On a calm gulf morning it is smooth; when the wind is up the hull thuds over the swell and the crew asks you to stow phones in dry bags for the open stretch. The seats at the back move least. Pregnant travellers and anyone with a back or neck problem should read the restrictions on the listing rather than negotiating at the pier.
Storage on a speedboat is a shelf. Swimwear under your clothes, a hat that survives wind, reef-safe sunscreen, a towel, and cash for the THB 50 landing fee and a drink at the island bar cover most of it. Wear footwear you can soak; boarding happens through shallow water.
See what the catamaran changes and who it suits.
When the wind is up, yes, though the crossing is short enough that most people simply grip the rail for ten minutes. The catamaran is the answer if you know you get seasick.
Ten to twenty minutes from Thong Krut on a calm day and up to half an hour in chop, then about fifteen minutes between Pig Island and Koh Tan.
The sunset departure. It carries the most reviews of the three and the afternoon slot has fewer boats on it.
