A Santorini private boat cruise lasts 5 hours on a catamaran or a sailing boat, 1 to 5 hours by speedboat and 10 hours on the island run. All 11 listings read for the party question carry the private label, with booking limits from 6 to 999 guests.
To set a boat day beside a day on land, the Greece Tours homepage lists tours by island and by region.
Who sails with you on a Santorini private boat cruise?
Your own party and the crew sail on a Santorini private boat cruise. All 11 listings read for this section carry the Private group label. Their booking forms set a party limit from 6 to 999 guests.
The word private sits in the title of all 11 listings. One title adds exclusive and one adds customizable. None uses semi-private, so each Santorini private boat cruise here is sold as private. Ten carry a category label: Water activity (six), Private tour (three) and Day trip (one).
The summaries add other words. One says the trip is for your family and friends. Two say personalised, one says tailor-made and three use a form of customise. Each of these phrases sits in a summary, so read the summary as well as the title.
On a Santorini private boat cruise, every booking form states a minimum and a maximum party. Ten of the 11 set the minimum at 1 guest, and one speedboat listing sets it at 2. All 11 state a maximum, and it runs from 6 guests to 999. Three set it above 60.
No summary gives the number of guests the boat holds. The form limit is the only party number a listing offers. MITOS is the Greek government’s procedure portal. It says a professional boat needs safety gear for its highest number of persons on board. Ask the operator of a Santorini private boat cruise for it.
The portal says a professional boat keeps its sailing permit on board for port officers to check. The port authorities issue it. Above 12 passengers, a passenger ship or fast craft has everyone counted before it sails. Yachts and pleasure craft sit outside that rule. Before the party boards a Santorini private boat cruise, ask to see the permit.
The forms count guests in two ways. Seven listings book a group of up to 4 guests. One books a group of up to 2, and three book per person. One of the 11 listings carries the wheelchair-accessible label. Two summaries name a crew role, and none states a crew count for a Santorini private boat cruise.
Which kinds of vessel sail a Santorini private boat cruise?
The 18 listings read for this page show four kinds of vessel on a Santorini private boat cruise. Catamarans lead with 8, then speedboats with 5, sailing boats with 2 and one RIB. Two listings name no vessel. Yachts have their own guide on this site.
Eight listings use a catamaran, and five say so in the title. That makes the catamaran the largest group of vessels on a Santorini private boat cruise. Their forms allow parties of 9 to 999 guests. For the catamaran day on its own, read our Santorini catamaran cruise guide.
Three catamaran summaries add a word about the boat: spacious and comfortable in one, and luxury in two. None of the three states a boat length, a deck count or a toilet. A guest reads the title and the form limit of a Santorini private boat cruise first. The operator answers the rest.
Two listings sell a sailing trip. Their forms allow 10 and 16 guests. One summary says seaworthy hull. The other lets the guest steer the wheel when conditions allow. Neither names its hull type. Wikipedia puts a sailboat’s ballast at 20 to 50 percent of its displacement. A catamaran uses the width of its hulls instead and carries none.
Five listings use a speedboat. Their forms allow 4 to 16 guests, and two set a minimum of 2. Wikipedia calls a motorboat that cruises at a much faster speed a speedboat. It adds that high-performance speedboats can pass 50 knots. None of the five listings of a Santorini private boat cruise states a speed.
One listing uses a RIB, a rigid-hulled inflatable boat. Wikipedia says air tubes along its sides keep it afloat when it takes on water. The article puts common RIB length at 4 to 9 metres. Its example is a 6 metre RIB with six passengers and a top speed of around 30 knots.
The RIB form allows up to 6 guests. A party of 9 clears the form limit on all 8 catamaran listings and on both sailing listings. It clears only 1 of the 5 speedboat listings and not the RIB. Pick the vessel before you pick the date for a Santorini private boat cruise.
How far can you shape the route of a Santorini private boat cruise?
Five of the nine listings read for this section word a Santorini private boat cruise as customisable, tailor-made or personalised. None calls its route fixed, and one lets the party choose from six islands.

The five listings use three words: customisable in two, tailor-made in one and personalised in two. A tenth listing, read for this page, offers a suggested route that the party can change with the captain. Each of these wordings puts the route of a Santorini private boat cruise in the hands of the party.
The island run is the widest choice, because its summary names no stop on Santorini. One speedboat listing lets the party pick Ios, Anafi, Folegandros, Sikinos, Koufonisi or Mykonos. Wikipedia says Ios sits halfway between Naxos and Santorini, and Anafi lies east of Santorini. Its Folegandros article puts Folegandros, Sikinos, Ios, Anafi and Santorini in the southern Cyclades.
Another listing lets the party pick a day sail or a sunset sail. Two others are sunset cruises by title, and one is a morning cruise. No summary states a clock time. The start hour of a Santorini private boat cruise is a question for the operator, so ask for it first.
Seven of the nine name a swim stop, and three add snorkelling. Three send the party to the Volcano by that word. None of the nine names Nea Kameni or Palea Kameni. Four of the nine use the word caldera. A Santorini private boat cruise therefore leaves the exact swim stop to the operator.
- Nea Kameni: Wikipedia says visitors land and climb a gravel path to the crater.
- Hot springs: Wikipedia says Palea Kameni holds a hot spring and that a swim from Nea Kameni reaches the island. Only the morning listing names the hot springs.
- Thirasia: only one sunset listing names it, and Wikipedia gives the island 9.299 square kilometres and five villages.
- Lighthouse: only the morning listing names the Akrotiri lighthouse, which it passes.
- Beaches: the morning listing swims at the Red Beach and passes the White Beach. One speedboat listing visits the Red and White Beaches.
- Oia: none of the nine names the town. The two sunset listings promise the sunset over the volcanic landscape and from the boat.
For the wider choice of boats on the same water, read our boat cruise Santorini caldera guide. No summary says how late the party can change the route, so ask that too. Each of the nine listings above carries the Private group label.
What food and drink does a Santorini private boat cruise set out?
A Santorini private boat cruise sets out a cooked meal and drinks on the catamarans and snacks on the speedboats. Of the 16 listings read for this guide, 14 name food, 13 name drinks and 4 name an open bar.
The barbecue shows in 3 of the 16 listings. One says the guide prepares the lunch on board. One calls the barbecue freshly prepared and offers a day or a sunset sail. The third pairs the barbecue with wine, beer or soft drinks.
Fresh food is the other wording on a Santorini private boat cruise. Three listings call the meal fresh or freshly prepared. Two of them pair it with an open bar, and both sail 5 hours on a catamaran. The third is the barbecue listing that offers a day or sunset sail. A fourth listing, a speedboat trip, names fresh fruits.
Mealtime follows the hours. Two catamaran trips of 5 hours name a lunch. Three sunset trips of 5 hours name a dinner. One words the meal as a Mediterranean dinner and one as a Greek dinner. The third names dinner on a sailing boat. A private sailing listing names lunch or dinner with an open bar.
The Mediterranean wording has a wider meaning. UNESCO places the Mediterranean diet on its Representative List of the Intangible Cultural Heritage of Humanity. Greece is one of the 7 countries named. UNESCO says eating together is the foundation of cultural identity across the Mediterranean basin. On a private boat that table belongs to your own party.
Drinks run from a full bar to a short list. Four listings name an open bar. One lists wine, beer or soft drinks and puts unlimited drinks in its title. Another lists soft drinks with snacks.
A choice appears in 3 listings. One offers wine, beer or soft drinks, one offers lunch or dinner, and one offers an optional lunch stop.
Speedboat listings carry lighter food. The 3-hour morning listing names soft drinks and snacks. Another 3-hour speedboat listing names premium snacks, fresh fruits and an optional lunch stop. The 3-to-5-hour speedboat listing puts food and drinks in its title. For a full meal on a Santorini private boat cruise, pick a catamaran. For a light bite, pick a speedboat.
How long does a Santorini private boat cruise last on each type of vessel?
A Santorini private boat cruise runs 1 to 5 hours by speedboat and 5 hours by catamaran or sailing boat. One listing from the cruise port runs 4 hours, and one private speedboat island run takes 10 hours.
Speedboats carry the widest spread of hours. Four listings state 1 to 4 hours, 3 hours, 3 hours and 3 to 5 hours. The 1-hour end belongs to a listing that offers swimming options along the volcanic coastline.
The 3-hour morning speedboat trip names a swim and snorkel stop in coves. It adds a visit to Red Beach and White Beach. The other 3-hour speedboat trip names an optional lunch stop. A 3-hour Santorini private boat cruise by speedboat leaves the rest of the day free.
Ten listings state a flat 5 hours. Seven name a catamaran, 2 name a sailing trip and 1 names no vessel. So a 5-hour trip is a catamaran in 7 of the 10 listings.
The start of those 5 hours differs on a Santorini private boat cruise. One catamaran listing offers a day or a sunset sail. Three more 5-hour listings are sunset trips with dinner. The morning start belongs to the 3-hour speedboat trip.
The 4-hour listing sails from the cruise port on a luxury catamaran. It names swim and snorkel stops and a meal with drinks. That is 1 hour under the 5-hour catamaran trips, and it still lists a meal.
The longest private trip is a 10-hour speedboat run. The listing lets the party choose one island: Ios, Anafi, Folegandros, Sikinos, Koufonisi or Mykonos. The choice decides how far the 10 hours reach on this Santorini private boat cruise.
Wikipedia puts Ios halfway between Naxos and Santorini and Sikinos midway between Ios and Folegandros. It puts Anafi east of Santorini. Ios, Anafi, Folegandros and Sikinos each belong to the Thira regional unit, the same unit as Santorini. Koufonisi is part of the Municipality of Naxos and Lesser Cyclades. Mykonos lies between Tinos, Syros, Paros and Naxos.
Yacht trips run to their own hours and have their own private yacht cruise guide on this site. Self-drive trips follow other hours, and the licence-free boat rental guide covers them.
