- Private speedboat charters on Koh Samui start at ฿30,000 per boat for an 8-hour day on Anda, for up to 6 guests.
- Pearl is the best all-round choice for small groups: hotel transfer included, up to 15 guests, and Koh Tao and Koh Nang Yuan for ฿41,000.

The breakfast table at the hotel turns into a planning meeting: four friends want Koh Tao, the parents want an easy beach day, and someone has a list of nine speedboats open on a phone. They all look white, fast and similar in the photos. They are not.
This guide compares every boat you can book for a speedboat charter on Koh Samui through chartersamui.com: length, engines, how many guests, where each one goes and what it costs. Then the part the spec sheets skip: what those numbers feel like on the water, and which boat I would book for each kind of group.
Speedboat charter Koh Samui: which boats can you book?
There are nine private speedboats, from a 38 ft boat for up to 8 guests to a 50 ft boat for up to 37. Every charter is private: the whole boat with captain and crew for your group only, priced per boat and not per person.
The prices below are per boat for the listed base group. The base group is the number that changes everything: most boats include 6 guests, Summer Casa and Coco Cay only 2, Neverland 10. Extra guests are added at ฿1,000 or ฿2,000 each, depending on the boat.
| Boat | Length | Engines | Max guests | Price covers | Extra guest | Price range |
|---|---|---|---|---|---|---|
| Anda | 38 ft / 12 m | 2 x 200 hp Yamaha | 12 | 6 guests | ฿1,000 | ฿30,000 - ฿32,000 |
| Pearl | 38 ft / 12 m | 2 x 200 hp Suzuki | 15 | 6 guests | ฿2,000 | ฿38,000 - ฿41,000 |
| Ruby 38 | 38 ft / 12 m | 2 x 300 hp Mercury Verado | 8 | 6 guests | ฿2,000 | ฿40,000 - ฿46,000 |
| Ofcourse | 38 ft / 12 m | 2 x 300 hp Mercury Verado | 24 | 6 guests | ฿1,000 | ฿40,000 - ฿47,000 |
| Sapphire | 38 ft / 12 m | 2 x 300 hp Mercury Verado | 24 | 6 guests | ฿1,000 | ฿40,000 - ฿47,000 |
| Ti Ti | 38 ft / 12 m | 2 x 300 hp Mercury Verado | 24 | 6 guests | ฿1,000 | ฿40,000 - ฿47,000 |
| Summer Casa | 44 ft / 14 m | 2 x 250 hp Yamaha | 10 | 2 guests | ฿2,000 | ฿38,000 - ฿62,000 |
| Coco Cay | 44 ft / 14 m | 2 x 250 hp Yamaha | 10 | 2 guests | ฿2,000 | ฿38,000 - ฿61,000 |
| Neverland | 50 ft / 15 m | 3 x 250 hp Honda | 37 | 10 guests | ฿1,000 | ฿47,000 - ฿53,000 |
The lowest number in each range is usually Koh Phangan or the islands to the south (Koh Tan, Koh Madsum and Koh Rap); the highest is Koh Tao and Koh Nang Yuan. All boats can be compared on the speedboat rental page.
What do length, engines and capacity change on the water?
More length usually means a softer ride in a chop, more power means the boat keeps its pace with a full load, and a higher capacity than your group size means space to stretch out. None of these makes a boat "better" on its own; it depends on your route and your group.
Here is how I read a spec sheet before a trip:
- Length: a 44 or 50 ft hull spreads its weight over more waves than a 38 ft one. On a flat day you will not notice; on a windy afternoon crossing back from Koh Tao you will.
- Engines: two 300 hp engines on a 38 ft boat (Ruby 38, Ofcourse, Sapphire, Ti Ti) give plenty of reserve. Two 200 hp engines (Pearl, Anda) are perfectly fine for a small group, they simply have less in hand when the boat is full.
- Capacity versus your group: ten people on a boat rated for 24 feel relaxed; twelve people on a boat rated for 12 means every seat is taken.
- Distance: Koh Tao lies about 45 km north of Koh Samui, the farthest of the usual routes, so it is where power and length matter most. Koh Tan and Koh Madsum, just south of Samui, are short hops where any boat does the job.
Speedboats are the fastest way to the islands, but they also feel the sea more than a catamaran or a big motor yacht. If anyone in your group gets seasick easily, choose a longer boat, sit towards the back where the motion is gentler, and keep the longest crossing for the morning, when the sea is often calmer.
Which speedboat is best for a small group of 2 to 8?
For most small groups the answer is Pearl: hotel transfer is included, the price covers 6 guests, and its five full-day routes run from ฿38,000 to ฿41,000. It is also the most booked speedboat on chartersamui.com, and for good reason.
Pearl is a 38 ft fiberglass boat with two 200 hp Suzuki engines and room for up to 15 guests. The price includes captain and crew, hotel transfer, a guide, travel insurance, soft drinks, water, fruit, snacks, snorkeling masks, life jackets and fuel surcharge. Koh Tan and Koh Madsum or a loop around Koh Phangan cost ฿38,000, Ang Thong or a day around Koh Samui ฿39,000, and Koh Tao ฿41,000.
Ruby 38 is the step up for a group of up to 8 who want a sportier boat. It is a Sports Cruiser 38 with two 300 hp Mercury Verado engines and a top speed of up to 68 km/h, with a rear cockpit, a couch and open bow seating. Hotel transfer, a licensed captain, a sailor and an English-speaking guide are included, and routes cost ฿40,000 to ฿46,000. The catch: it takes 8 guests at most, so it is not the boat for a group that might grow.
My honest take: for a family of four or a group of six friends, Pearl gives the best value of the two. Choose Ruby 38 if the extra power and the cruiser layout matter to you, or if you want the feeling of a smaller, more private boat. The Pearl speedboat page lists every route and price.
Which speedboat suits a couple or a half day?
Summer Casa and Coco Cay are the two boats priced for 2 people, and the only speedboats here with 4-hour trips. For a couple, a honeymoon or a family of three, they are often a better fit than a 6-guest price you will not use.
Both are 44 ft boats with two 250 hp Yamaha engines, up to 10 guests, a butler on board, an onboard toilet, a sun bed and a paddle board. The price includes drinking water, soft drinks with ice, seasonal fruit, snacks, a beach picnic, snorkeling equipment and travel insurance. Both leave from the Naval Base on Koh Samui.
The half day is the reason to look at them. Koh Tan and Koh Madsum in 4 hours cost ฿38,000, Koh Phangan in 4 hours ฿43,000, while full days run to ฿53,000 for Koh Phangan, ฿56,000 for Ang Thong and ฿61,000 (Coco Cay) or ฿62,000 (Summer Casa) for Koh Tao. Extra guests cost ฿2,000 each; children up to 5 travel free, from 6 they count as adults.
Who should skip them? A group of six or more: with a base of only 2 guests, the price climbs quickly, and a 6-guest boat like Pearl usually makes more sense. The toilet on board, though, is a real argument for families with small children.
A short guide to the small-boat choice: Pearl for most families and friends, Ruby 38 for up to 8 who want more power, and Summer Casa or Coco Cay for couples and half-day trips.
Which speedboat is best for a big group?
Neverland is the speedboat for big groups: 50 ft long, three 250 hp Honda engines, up to 37 guests, and 10 guests already in the base price. For groups of 10 to 24, Ofcourse, Sapphire and Ti Ti are the other choice.
Neverland runs four full-day routes: Koh Phangan or Koh Tan, Koh Madsum and Koh Rap for ฿47,000, Ang Thong for ฿51,000 and Koh Tao for ฿53,000. Extra guests beyond 10 cost ฿1,000 each, up to 37. Snorkeling masks and life jackets are on board; lunch and fishing gear are extra, and hotel transfer and kayaking are not included.
Ofcourse, Sapphire and Ti Ti are close relatives: 38 ft, two 300 hp Mercury Verado engines, a top speed of 40 knots, up to 24 guests, a base of 6 and ฿1,000 per extra guest. All three cost ฿40,000 for Koh Phangan or the southern islands, ฿44,000 for Ang Thong and ฿47,000 for Koh Tao, with a licensed guide, snorkeling equipment, drinks and fruit included. Hotel transfer is not included on any of them.
Which to choose? For 10 to 15 people, any of the trio works well, and the choice comes down to which is free on your date. Above about 20, I would lean to Neverland: three engines and 50 ft of hull make a full boat feel less full. For groups even bigger than that, the guide to group boat charters for 20 to 70 guests covers catamarans and the junk.
All of these four also offer a scuba dive add-on (equipment, instructor and 2 dives) for ฿4,500, handy when a few people in the group dive and the others snorkel.
Which speedboat is best for Koh Tao and Koh Nang Yuan?
For a small group, Pearl is the best value to Koh Tao at ฿41,000 with transfer included. For a group that wants more power on the longest crossing, Ruby 38 (฿46,000) or one of the 300 hp trio (฿47,000) are worth the difference.
Koh Tao is the farthest of the usual speedboat routes, about 45 km north of Koh Samui. The longer the crossing, the more the boat matters: a strong, well-loaded boat gets you there sooner and leaves more of the 8 hours for the reefs around Koh Nang Yuan. Anda does not run a Koh Tao route at all, so the cheapest boat in the list is out for this trip.
The full Koh Tao price ladder looks like this: Pearl ฿41,000, Ruby 38 ฿46,000, Ofcourse, Sapphire and Ti Ti ฿47,000, Neverland ฿53,000, Coco Cay ฿61,000 and Summer Casa ฿62,000. Koh Nang Yuan charges ฿250 per adult and ฿125 per child (from 12 years children pay as adults), paid on top.
One honest warning: from about November to January the north-east monsoon can make the sea rough, and Koh Tao, the longest open-water route, is the first to feel it: trips may change route or be postponed. Keep a back-up day if Koh Tao is the highlight of your holiday. The route and the islands are described on the Koh Tao and Koh Nang Yuan charter page.
What is the cheapest speedboat charter on Koh Samui?
Anda is the cheapest: ฿30,000 for an 8-hour day to Koh Phangan or to Koh Tan, Koh Madsum and Koh Rap, and ฿32,000 for Ang Thong, for up to 6 guests with hotel transfer included.
Anda is a 38 ft boat with two 200 hp Yamaha engines, a top speed of 40 knots and room for up to 12 guests. The price covers captain and crew, travel insurance, fuel surcharge, hotel transfer, soft drinks, water, fruit, a licensed guide, snorkeling equipment and fins. Each extra guest costs ฿1,000, up to 12.
What you give up: no Koh Tao route, and a maximum of 12 guests. For a group of up to 12 heading to Koh Phangan, the southern islands or Ang Thong, I see no reason to pay more unless you want a specific boat.
When you compare budget options, compare like with like. Ofcourse, Sapphire, Ti Ti and Neverland do not include hotel transfer, while Anda, Pearl and Ruby 38 do. Lunch is extra on every speedboat.
In short: Anda for the lowest price on the shorter routes, Neverland for really big groups, and Ofcourse or Sapphire for groups of 10 to 24 who want two 300 hp engines under them.
Before you book: fees, season and the fine print

- Lunch: not included on any speedboat; on some boats it can be added for an extra charge.
- Transfer: included on Anda, Pearl and Ruby 38; not on Ofcourse, Sapphire, Ti Ti and Neverland. Summer Casa and Coco Cay leave from the Naval Base.
