- The Power Catamaran 72ft is the largest boat for charter in Krabi with Charter Krabi and takes up to 70 guests with captain and crew.
- Its prices are for 1-10 guests: ฿35,000 for a 2-hour Krabi River cruise, ฿55,000 for a 4-hour 4 Islands cruise and ฿75,000 for a full day at Koh Hong.
- Each extra adult costs ฿600 and each child aged 3-12 costs ฿300, up to the 70-guest limit.
- For groups of up to 25 or 30, the Power Catamaran 40ft and the sailing catamaran Blue Atoll are smaller alternatives.
- Two boats make sense when the group is larger than one boat allows or when part of the group wants a quiet day and part wants a party.
Forty colleagues on the pier at nine in the morning, a wedding party with grandparents and toddlers, a reunion of three families from different countries: big groups ask the same first question. Can we all be on one boat? A group boat charter Krabi trip is possible for up to 70 guests, and this guide shows how it works, what it costs and when it is wiser to split up.
It is written for the person who has to organise everything: the HR manager, the bride's sister, the uncle who said "leave it to me". The point is to help you choose the right boat and route, avoid the classic mistakes, and get everyone back on the pier happy.
Which boat in Krabi takes a group of up to 70 guests?
The Power Catamaran 72ft is the boat for big groups: a custom-built motor catamaran of 72 ft (22 m) that takes up to 70 guests. It is the largest boat in the Charter Krabi line-up, and it is chartered for one group only, with captain and crew.
Two hulls give it a wide, stable deck, which matters with a crowd. People can move around, sit in groups, and spread out between the shaded upper deck and the open front. At the bow there is a mesh net, as on a sailing catamaran, where guests can lie above the water.
The boat has 4 double cabins. On a day trip they are useful as quiet spots, places to change or a corner for a nap for small children. The water toys are on board too: snorkelling equipment, a stand-up paddle board, a kayak and a fancy swim ring.
Captain and crew, accident insurance, the fuel surcharge, a dinghy, coffee and tea, soft drinks with ice, seasonal fruits and snacks, life jackets and full safety equipment are part of the price. You can see the full details on the Power Catamaran 72ft page.
How much does a group boat charter in Krabi cost?
On the Power Catamaran 72ft the route price covers 1-10 guests, and every guest beyond that is added at a fixed rate. Each extra adult costs ฿600 and each child aged 3-12 costs ฿300, up to 70 guests.
Here are the three routes of the 72 ft catamaran and the prices for the whole boat:
| Route | Duration | Price for 1-10 guests | Extra adult | Extra child 3-12 |
|---|---|---|---|---|
| Krabi River cruise | 2 hours | ฿35,000 | ฿600 | ฿300 |
| 4 Islands cruise | 4 hours | ฿55,000 | ฿600 | ฿300 |
| Koh Hong full day | 8 hours | ฿75,000 | ฿600 | ฿300 |
The way this pricing works favours big groups. The base price is fixed, and the extra cost per guest is small, so the more people you bring, the lower the share for each person. For a group of 15, the 72 ft boat is probably more boat than you need; for a group of 50, it is a very good deal compared with booking a shared tour for everyone.
To get the exact figure for your group, send the number of adults and the number of children with their ages. The manager confirms the final price, so you do not have to calculate it yourself. Children under 3 are not listed in the extra-guest prices, so ask about them when you book.
Keep in mind what is not in the boat price. Koh Hong and the 4 Islands sit inside national parks, so a park fee may be collected per person on the day. It is usually not part of the boat price, and with 60 people it is worth knowing in advance who pays it and how.
Which routes work best for big groups?
For most groups the 4 Islands cruise of 4 hours is the sweet spot: short crossings, several stops and back in time for the evening. The full day at Koh Hong suits groups who want a real day at sea, and the 2-hour river cruise suits groups with little time or mixed ages.
The 4 Islands route on the 72 ft catamaran covers Poda Island, Chicken Island, the Talay Waek sandbar and Railay. With a big group, the short hops are a blessing. Nobody is stuck on a long crossing, people who want to swim can swim, and people who want to stay on board under the shade can do that.
The Koh Hong full day of 8 hours is the more scenic choice. Koh Hong is known for the lagoon closed in by limestone walls, and the water inside is calm. With a big group it is a long day, so it works best for groups who are fit, like the sea and do not have an evening event planned. The Hong Island charter page explains what you see there.
The Krabi River cruise of 2 hours stays on the river and away from the open sea. It is the easy choice for a welcome event, a short team outing or a group with elderly guests. It also stays possible on many days when the sea is too rough for the islands.
One honest note: the 72 ft catamaran does not have a Phi Phi route in its prices. If Phi Phi is a must for your group, look at the smaller boats below, or split the group.
How do you plan a company outing or a celebration on the water?
Plan the day around the group, not around the route: who swims, who does not, who has to give a speech and when people need to eat. Tell the manager the purpose of the trip when you book, because a team day, a wedding and a birthday need a different rhythm.
For a company outing, the most common mistake is too much schedule. People want time to talk, to swim and to sit in the shade, not a programme every half hour. One short welcome on board, one group photo, and then let the sea do the work.
For a wedding party or a big birthday, think about the moment you want. A toast at anchor in a calm bay, the cake on the way back, the photo with the cliffs behind. Mention it in the request so the crew can plan the stop, the shade and the timing.
Some practical points that save stress:
- Music. Ask what sound system is on board and if a phone playlist can be connected. Keep the volume friendly at busy beaches.
- Food and drink. Fruit, snacks and soft drinks are included. If you want a fuller meal, a cake or alcohol for a toast, ask the manager what is possible before the day.
- Dress code. White outfits and matching shirts photograph well, but remind everyone to bring swimwear and a change of clothes.
- Safety briefing. With a big group, ask everyone to listen to the crew at the start. It takes five minutes and matters a lot.
- Timing. Plan the return with a margin if there is a dinner or a flight the same evening.
And a word on alcohol: a boat full of people in the sun is not the place for heavy drinking. A cold toast is lovely; a group with people too tipsy to climb the ladder after a swim is a real safety problem. The crew will say so, and they are right.
What are the logistics for a big group on a boat?
The biggest logistics issue with a big group is getting everyone to the pier at the same time. Agree on the meeting point and time early, share it with every guest in writing, and plan transport so nobody arrives on their own.
With 40 or 60 people staying in different hotels, the morning can fall apart fast. Pick a single gathering point near the hotels, book enough vehicles, and add a buffer of at least half an hour. Ask the manager where the boat departs and how guests reach it.
A checklist that has saved many group days:
- Final head count. Send adults and children separately, with ages, as the price depends on it.
- A guest list. Have names written down so the organiser can count people back on board after each stop.
- Health notes. Tell the crew about non-swimmers, elderly guests, pregnancy or seasickness.
- Cash for the park fee. Decide in advance whether each guest pays or the organiser pays for all.
- Sun and water. Remind everyone to bring a hat, sunscreen and a water bottle.
- Weather back-up. From about May to October the monsoon brings swell, and routes can change. Ask what happens if the sea is too rough on your date.
Non-swimmers are more common in big groups than people expect, especially with mixed ages. Life jackets are on board, and the crew can help, but someone in the group should keep an eye on them during the swim stops.
When should a big group split into two boats?
Split into two boats when your group is larger than the 70-guest limit, or when two parts of the group want very different days. Two smaller boats can also go places the big catamaran does not, such as Phi Phi, and give each part of the group a better day.
The obvious case is size: 80 or 100 people need two boats. But size is not the only reason. A family reunion might include grandparents who want a calm 4 hours and teenagers who want to snorkel all day. A company might have a management group with a quiet dinner plan and a team that wants music and swimming.
The smaller catamarans are good partners for a split:
- The Power Catamaran 40ft takes up to 25 guests. Its 4 Islands half day costs ฿22,000 and the full day ฿29,000, and Hong Island costs ฿32,000, all for 1-10 guests, with each extra adult at ฿600 and each child aged 3-12 at ฿300.
- Blue Atoll, a Lagoon 400 sailing catamaran, takes up to 30 guests. Its prices are based on 10 guests, with extra guests from 11 to 30 at ฿1,000 each, and it has a full day to Phi Phi for ฿70,000. A massage therapist and a bartender are available for an extra charge.
Two boats can meet at the same island for a swim and a group photo, then go their own way. That gives you the shared moment without forcing everyone into the same day. Ask the manager to coordinate the timing if you want the boats to meet.
My view: for a single-purpose group like a wedding party of 50, one boat is better, because the point is to be together. For a mixed group with different energy levels, two boats almost always give a better day.
These are the boats to compare for a big group, from the 72 ft catamaran for up to 70 guests to the smaller catamarans for up to 25 or 30.
How to book a group boat charter in Krabi
Send the date, the number of adults and children with ages, the purpose of the trip and the route you prefer. A manager checks that the boat is free on your date and confirms the final price, and the request is free and non-binding.
Book early for big groups. A single large boat is easier to lose on a popular date than one of several smaller ones, and the high season from about November to April fills up. If your date is fixed, such as a wedding, ask as soon as you know it.
If you are still deciding between motor boats, the power catamaran overview compares the 40 ft and the 72 ft. When you are ready, write on WhatsApp or use the booking request form, and include every detail you already know: it makes the answer faster and more accurate.
Questions and answers
Can the group bring its own food and drinks on a charter?
Fruit, snacks and soft drinks are included on the Power Catamaran 72ft. If you want to bring a cake, special food or drinks for a toast, ask the manager when you book. Rules can differ by boat, so it is best to confirm in advance.
Is the 72 ft catamaran suitable for elderly guests?
Yes, it is one of the easiest boats for older guests, because the two hulls make it stable and there is plenty of shade. The 2-hour river cruise or the 4-hour 4 Islands cruise are the gentler options. Tell the crew about anyone who needs help getting on and off.
How far in advance should we book a boat for a large group?
As early as possible, especially for the high season and holiday dates. There is only one boat for groups of up to 70, so it can be taken on popular days. A free request lets you check the date without paying.
Can we have a wedding ceremony on the boat?
A celebration on board, such as a toast, a cake or a group photo at anchor, is easy to plan. For a formal ceremony with decorations or an officiant, discuss the details with the manager before booking. They will tell you what the boat and crew can arrange.
Do children pay the full price on a group charter?
On the Power Catamaran 72ft each child aged 3-12 beyond the first 10 guests costs ฿300, compared with ฿600 for an extra adult. Children under 3 are not listed, so ask about them when you book. Give the ages of all children in your request.
What happens if the weather is bad on the day of a group trip?
The captain decides on the morning whether the planned route is safe. On rough days the route may change to a shorter, more sheltered one, such as the river, or move to another date. Ask about the back-up plan when you confirm the booking.
Can we use the kayak and the paddle board with a big group?
Yes, a stand-up paddle board and a kayak are on board the Power Catamaran 72ft, along with snorkelling equipment and a swim ring. With a big group they are shared, so take turns at each stop. The crew tells you where it is safe to paddle.
