I have just got a sponsor and wanted to know if you can put it anywere or only in one area. Ihave a 4.7 sail so there is not must room . The other question is were do you have yoursponsor if you are sponsored.
As far as I know, there aren't restrictions on the location of sponsors, only whether you can display them or not. Category A events (I think) are unrestricted, category C events don't allow advertising at all, and a third category (like A-restricted or something) allows only the boat supplier to place sponsors on them, at supplied-events only.
category C is al advertising allowed as ross says, and in laser all races except the olympics are like this. You only have to keep the first 25 % off the hull free for event sponsors i believe. on the sail, you have to manage that the advertisment does not take away the visibility of your sailnumbers
