The security deposit serves as a precautionary measure in case any damage occurs to the yacht due to mishandling during the charter period. It is left at the base, either in cash or as a card authorization. The full security deposit will be refunded unless damage to the yacht has occurred.
It's important to note that the security deposit represents the maximum amount you can be charged. Any damages exceeding this amount will typically be covered by the insurance company, except in cases of gross negligence, where the insurance company may choose to pursue legal action against the skipper privately.
