All owners time bookings with Sunsail and the Moorings should be made directly with the company. The owner simply notifies the company that you will use a week of his guest allotment. You will get a standard contract.nthe base will not even know you are using owners time. The owner is paid directly. There is a per Diem charge that also has to be paid. It's generally 400 to 600 a week. That can be paid directly to Sunsail or the Moorings by the guest or the owner can include it in the price and pay it himself.
You should always have a contract in your name with either company so the risk is virtually zero. On occasion some owners will try and sell more time then their guest allotment. If your name is not shown on the contract then you need to get it added to insure its legit. If the owner refuses look elsewhere.
