How does the security deposit (credit card authorization) work?

The security deposit is $1,000 for each boat and $500 for each personal watercraft. Security deposits help cover problems or accidents that occur during a reservation, like low fuel, damages, missing equipment or an unreturned key. At time of rental, an authorization hold will be secured on the credit or debit card provided. These funds will not be available for your use. The authorization hold will be released when the equipment is returned in the same condition as you received it. The time it takes to release this additional authorization depends on your bank and is beyond the control of All-In Boat Rentals. The average transaction reversal is typically seen within 3 to 5 business days on a credit card and up to 21 days on a debit card.
