Boat trips
Day trips
The island
Private boat trips on Kos are priced per boat, not per head, which means the answer to "is it worth it?" is arithmetic rather than opinion. Here is the break-even group size, what the skipper does and does not include, and what "private" genuinely guarantees.

Quick summary
| Price from | Roughly €250–500 per boat for a half day and €300–800+ for a full day, depending on size and season. |
|---|---|
| Departure times | You choose, inside the operator's working day. Morning starts get the flat water. |
| Advance booking? | Yes. Each boat sells one charter per slot, so July and August book out weeks rather than days ahead. |
| Time to allow | 3–5 hours for a half day, 7–8 hours for a full day, plus getting to the quay. |
| Skipper | Included on almost all private listings. Check — a few are self-drive rentals sold as "private". |
| Break-even | Against a €50 group ticket, a €600 full-day charter needs 12 people. Against a €90 premium cruise, about 7. |
| Food and drink | Often not included. Bring a cooler, or pay for catering as an add-on. |
| Fuel | Usually inside the charter price on skippered boats — but confirm, and ask whether extra hours are billed. |
| Weather | Cancelled or re-routed on meltemi days. A skipper will change the plan rather than lose the day. |
Price bands are ranges from publicly listed operator prices, not quotes; capacity and inclusions differ by boat. How we source numbers.
Read this before you pay
Check maximum capacity before price. A charter that legally carries eight cannot be split by ten, and capacity is the number that decides whether the maths works at all. It is stated on the listing — and it counts children.
Per boat versus per person
Group cruises are sold per person, private charters per boat. That single difference is the whole decision, and it is worth doing on paper rather than by feel — the answer flips somewhere between four and twelve people depending on what you compare against.
Take a full-day charter listed at €600. Set against a standard group cruise ticket at about €50 a head, you need 12 people to break even — more than most small charters can legally carry, so at that comparison private is a comfort purchase, not a saving.
Now set the same €600 against a premium small-group cruise at €90: break-even drops to about 7 people. And a €350 half-day charter against the same €90 seat breaks even at four. Two families travelling together are usually already past the line.
Do this with the real numbers on your own listing, and count children at the group boat's child rate rather than the adult one — that is where the sums most often shift.
| Charter price | vs €50 seat | vs €90 seat |
|---|---|---|
| €350 half day | 7 people | 4 people |
| €500 full day | 10 people | 6 people |
| €600 full day | 12 people | 7 people |
| €800 full day | 16 people | 9 people |
Simple division of listed price bands, not quotes. Charter capacity is often lower than the break-even number, which is the point of the table.
What "private" does not guarantee
It buys you the boat, not the sea. A private charter does not guarantee a specific bay (wind decides), an empty anchorage in August, dolphin sightings, calm water, or a return at a minute you name. It does guarantee no strangers, no queue for the ladder, your own music and swim stops as long as you want them. Anyone promising more than that is overselling.
Charter comparison
Three ways to have a boat to yourselves from Kos. Group size decides the first question, temperament decides the second.
Option 1
€250–500 / boat, 3–5 hours
Pick this if you want the privacy without the whole day, or you are travelling with toddlers who will be done by lunch.
Option 2
€300–800+ / boat, 7–8 hours
Pick this if there are six or more of you, or you are comparing against premium small-group cruises rather than the cheapest group boat.
Option 3
€120–200 / boat per day, plus fuel
Pick this if someone is genuinely comfortable at a helm and you are four or five people. Full detail on the boat hire page.
The one instruction worth giving
Tell the skipper: "we want to be somewhere before the day boats get there." A local crew knows the arrival pattern of the excursion fleet and will happily run the classic route in reverse so you swim in an empty bay. It costs nothing and it is the single biggest advantage a charter has.
What to ask for
Charters are sold as a boat and a skipper, not a fixed route. Say what kind of day you want and let the crew shape it around the wind.
Most Kos charters do not include food. You will normally be offered water and soft drinks, sometimes fruit, and given the choice of bringing your own cooler or adding a catering package. Bringing your own is far cheaper and lets you feed children on their schedule; catering is worth it when nobody wants to shop at 07:30. Ask whether alcohol on board is permitted, because policies differ.
Tipping is customary but not obligatory in Greece, and a skipper who has spent the day finding you empty water has earned something. Ten per cent of the charter, or a round sum handed over at the end, is normal and welcome. Take cash — there is nothing to tip through at sea.
Who it is really for
Price aside, there are travellers for whom a charter is not a luxury but the only version of the day that works.
Ask these three questions before you pay
One: is a skipper included, or is this a self-drive rental sold as private? Two: what is the maximum capacity, counting children? Three: what is the cancellation and bad-weather policy, and are extra hours billed? Those three answers separate a good charter from an expensive misunderstanding.
Timing
The meltemi is the dry northerly that blows down the Aegean all summer, peaking in July and August and building through the afternoon. This is where a charter earns its money: instead of a fixed route sailed regardless, a local skipper moves the day to the sheltered side of the island. Charters therefore lose fewer days than self-drive rentals, which are grounded first.
Book early morning for flat water and clean light, and put the boat day in the first half of your holiday so a genuine cancellation still leaves room to move it.
Out by 09:00 and anchored by ten puts you in the good bays before the excursion fleet arrives around midday. Late-afternoon charters get warmer water and better photographs; the trade-off is chop on the run home.
How to save
Cost per head falls with every seat used, so find the other family. Two households of four on one eight-person charter is the commonest way people end up paying near group-ticket prices for a private day.
A morning half-day gets the flat water and the empty anchorages for meaningfully less than a full day. Combine that with late September, when charter rates soften while the sea is at its warmest, and the same boat can cost a third less than in August.
Catering packages are convenience, not value. A supermarket cooler of water, ice, fruit, bread and cheese costs a fraction of the add-on, and children eat when they are hungry rather than when lunch is served.
For two people, a private boat is almost never the rational choice — take a group cruise or a small caique. And there is no island-wide sightseeing pass on Kos: no card, no combo, no membership makes a charter cheaper. The only levers are group size, duration and season.
| How you do it | Per head |
|---|---|
| Group cruise ticket | €35–60 |
| Charter split by 8 | €60–110 |
| Premium small-group cruise | €80–140 |
| Charter split by 4 | €90–200 |

How to get there
Most charters leave from the harbour below Neratzia Castle or the marina just east of it — both walkable or a flat cycle from central Kos Town.
Smaller charter fleets work from the north and south coasts. Kardamena is about 30 km from Kos Town, roughly 40 minutes by road, and the sheltered choice in a northerly.
KTEL local buses connect the resorts to Kos Town but run sparsely early. For a 09:00 departure from a resort, a taxi or a hire car is the realistic answer — see transfer options for how private transport is priced here.
Some charters will collect you from a beach jetty nearer your hotel, which removes the transfer entirely. It is rarely advertised and often possible — put the request in the booking notes.
Context
Kos sits in the Dodecanese, a chain along the Turkish coast, and the water around it is unusually generous to small boats: islands to the north, sheltered bays on the south and west, and the Turkish shore close enough to see. A dozen operators sell the same group route out of the same harbour, so the private fleet grew in the gap left over — travellers who wanted that water without the shared deck.
Most of these boats are family businesses rather than yacht companies. The skipper is often the owner, frequently from a fishing or sponge-diving background of the kind Kalymnos made famous, and their local knowledge is the actual product. They know which bay works in a northerly, when the excursion fleet reaches Pserimos, and where the bottom is sand rather than protected seagrass.
That is also the limit of what a charter can do. It cannot cross to Nisyros and give you time in the crater — that needs the purpose-built day boat. It will not beat the price of a group ticket for two people. And it cannot make August quiet. What it reliably delivers is control: your timings, your music, your swim stops, and an anchorage chosen for you rather than for two hundred people.
If you are still deciding, the Kos boat-trip overview lines every format up side by side, the pirate cruise is the loud family alternative, and the excursions hub covers the land days you should keep free between boat days.
FAQ
Listings run roughly 250 to 500 euros per boat for a half day and 300 to 800 or more for a full day, depending on the size of the boat and the season. The price is for the whole boat, not per person, so cost per head depends entirely on how many of you there are. Catering and tips are usually on top.
It depends what you compare against. A 600-euro full-day charter needs about twelve people to beat a 50-euro group ticket, which is more than most small boats can carry. Against a 90-euro premium small-group cruise the same charter breaks even at about seven, and a 350-euro half day breaks even at four. Two families travelling together are usually already past the line.
On almost all private charters, yes, and the skipper is the main reason the day works: they read the wind, pick the anchorages and re-plan when the meltemi builds. A few listings described as private are actually self-drive rentals, so check the wording. If nobody in your group wants to be responsible for a boat, make sure a skipper is named in the inclusions.
Yes, within reason. Tell the skipper what kind of day you want — snorkelling anchorages, a beach hop, the classic island route run in reverse to avoid the group boats — and let them shape it around the wind and the sea state. What you cannot do is override a safety call about where the boat can go.
Usually not. Water and soft drinks are common, sometimes fruit, and catering is offered as a paid add-on. Bringing your own cooler is considerably cheaper and lets you feed children when they are hungry rather than when lunch is served. Ask whether alcohol on board is allowed, because policies differ between operators.
They are the best option on the island for both. You get shade you do not have to claim at boarding, a toilet on demand, swim times on your own schedule and the freedom to go back early. Non-swimmers can stay aboard without missing the day and there is no queue behind them on the ladder. Put any mobility or boarding requirement in the booking notes.
Tipping is customary but not obligatory in Greece. Around ten per cent of the charter price, or a rounded sum handed over at the end of the day, is normal and appreciated. Take cash, because there is nothing to tip through at sea.
A skipper will usually re-route to the sheltered side of the island rather than cancel, which is one of the real advantages over a fixed group itinerary and over a self-drive rental. If the sea makes the whole day unsafe, the standard remedy is a rebooking or a refund under the terms shown at checkout. Confirm that policy before you pay.
