With Sunsail/Moorings and probably footloose it varies. It can be done many different ways - I have those buying my time pay me directly as this gives them a single payment. Otherwise some payments would be made to Moorings/sunsail and some to the owner. This is something that just needs to be worked out with the owner.
But you can get a contract number once things are worked out and you can call the owners agent to verify. Feel free to PM me with any specific questions - I own a Moorings 43.3.
