Questions about Alive
How can I cancel my reservation?
Contact our customer service via email at info@yachtco.net. We will assist you immediately.
What is the security deposit?
The security deposit for Alive is 4.000 €. It is refundable: you leave it at the base at check-in — usually as a credit-card pre-authorisation or in cash — and it is returned at check-out if the boat comes back undamaged.
What licences do I need to rent Alive?
For a bareboat charter you need a skipper licence recognised in Croatia and a VHF radio certificate. The charter company checks both at check-in — there is no licence check when you book online. No licence? Add our skipper in the extras below: priced by the week, plus their food on board.
What additional costs should I expect?
Obligatory extras are listed on this page and are paid before arrival or at the base, as marked. On top of the charter price, budget for mooring fees outside your home marina, fuel and provisioning. The refundable security deposit is separate and is returned after check-out.
When do I check in and check out?
Check-in for Alive is from 08:00 on the day your charter starts, and check-out is by 16:00 on the day it ends. The charter company’s rule for this base: “Return on the evening before is desirable!”
Who operates Alive?
Alive is owned and operated by First Class Sailing, an independent charter company with 267 boats in our catalogue. We act as your charter agent: you book and pay through us, and First Class Sailing hands the boat over at the base.
