Telephone to be used only on Saturday of arrival in case of emergency: 347/6749599.
If you arrive late, from La Maddalena you can call a taxi (see contact details under Useful Phones - average price 23/30 Euro or more).
The Centro Velico Caprera does not organise group trips but points out the existence of a Facebook page dedicated to arrivals and departures so that participants can organise their trip better.
It is not recommended to arrive at the base bycar .
Access is only allowed up to the gate of the Precrociera dock, from there you wait for the arrival of the other students with the ferry from La Maddalena. For the duration of the course you will not have the opportunity to use it.
Cars are not allowed to circulate inside the Park, unless you have a special permit, which can be obtained directly from the Park Authority (Tel. 0789/79021).
It is advisable to leave them in Palau.
The base has three settlements on the south coast of the island:
- Punta Coda where initiation courses are usually held.
- Refinement, where other dInghy courses or cabin cruisers usually stay
- Pre-cruise, where the cabin courses usually stay.
There is a CVC infirmary at Punta Coda.
When disembarking from the ferry, the students of each course are assembled and assigned a place in the dormitories. You will take possession of your sleeping place, dressed appropriately for the swimming and scuba diving test (dInghy initiation courses) or for the activity on the boats. You will then be assembled in the classroom to receive instructions from the Chief of Instructors (Shift Leader) and base staff.
There are individual safety boxes in the Punta Coda Initiation settlement. You will be given the key against a deposit of 50 Euro. In the other settlements there are collective safes. The school is not liable for the theft of items left unattended. Avoid bringing valuables or excessive amounts of money.
Life on Caprera is regulated by the following timetable:
06.30 wake up
21.00 comments on the day
Particular attention is paid to resting during the night: very intense sporting activity does not allow hours of rest to be lost.
- Centro Velico Caprera is a sailing and sea school, not a holiday resort: attending courses requires commitment, discipline, a spirit of adaptation and acceptance of rules of behaviour. Access to the Bases is reserved only for those who are teachers or students on an ongoing course. Cars (which must remain outside the gate) or motorbikes, dogs or other animals are not allowed. Acceptance to courses is at the sole discretion of the School.
- Arrivals and departures must take place strictly in accordance with the scheduled dates and times. No responsibility is assumed by the Centre with regard to journeys to and from the Caprera base.
- You may not leave the base, even temporarily, except for justified reasons and with the authorisation of the base chief. Visits from relatives or friends are not allowed, without special permission from the base chief.
- Tidiness and cleanliness, which are essential in a community life, concern not only one's own person and personal belongings, but also the dormitories, common rooms and facilities, the surroundings, and the equipment and facilities of the Base. Vital to the School is the care of the boats and materials.
- Sleeping after a busy and tiring day is a sacred right, so all noise in the vicinity of dormitories must stop at the hour of silence. Small radios, cassette players and the like are not welcome and their use is forbidden in the common areas. Mobile phones are also to be used discreetly, but must be switched off during communal activities.
- On courses with dormitory accommodation, pupils are not permitted to attend the female students' dormitories and vice versa.
- Safety is a dominant theme in education both at sea and on land: from the obligation to wear a life jacket to rescue and fire-fighting equipment. Everyone contributes to the work of prevention, to avoid damage to people and equipment.
- The Head of the base has the right to remove from the base any student who proves to be unfit for community life at the school or who is guilty of serious misconduct.
- The use of boats is permitted for the School's institutional activities. Any other use must be authorised by the Base Head.
- In addition to personal telephones, to get in touch with students, from May to October, you can call the Secretariat in Caprera (0789/727769). During other periods, the secretariat is located on La Maddalena (tel. 0789/738529).
It is not allowed to use mobile phones on the boat or during lessons ashore.
Their use is only allowed during free time.
- All trainees participate in common activities (distributing meals, cleaning the mess, dormitories and toilets, helping in the sail room and on the boats). This will help to acquire the mentality of common life on a boat where the whole crew contributes to the activities on board.
For one day, in weekly courses, or two days, in fortnightly courses, each pupil is employed in the "command".
The CVC shop is at Punta Coda and at the Precrociera and is open every day (including Sundays).

Mineral water is provided free of charge at the table and on the boat. For personal use you can always top up your own water bottles from the water dispensers on the bases.
It is recommended that you bring your personal ASL card. There is an infirmary on Caprera.
If a transfer to a hospital in La Maddalena or Olbia is necessary, the student will have to pay for the transport back to the base.
- The last morning of your stay in Caprera is dedicated to tidying up the boats, the sails, the dormitories and the last bureaucratic formalities, including filling in the QUESTIONNAIRE (which you will have received by email in the early hours of the morning), where you can express your satisfaction with the school's activities and suggestions for improvement: we value your opinion! After filling in the questionnaire, you will have to prepare your luggage.
Students are brought back to La Maddalena around 12.00 noon by motorboat (before 1 May and after 31 October the motorboat will be replaced by a coach). From La Maddalena you can take a ferry to Palau and from Palau the regular bus to Olbia. We recommend booking a flight or ferry departing from Olbia from 18.00 onwards.
