The Advanced Provisioning Allowance is typically 25-30% of the charter fee for crewed yachts. It is paid to the captain, who draws from it to pay for mooring, fuel, food and expenses encountered by the guests whilst onboard. Whatever is left is returned or typically can be left as the tip.
I have used Hinde and Kitch on three occasions now and they have never disappointed. They go above and beyond to help with whatever is needed. Their guidance and professionalism is unparalleled, finding the perfect boat for our group and suggesting three fantastic spots for our holidays. We even got a yacht upgrade last year!
