For anyone having problems with the gate coming off - make sure you do not get any suntan lotion on the suction cups. Even just touching the cups hours after applying lotion can cause problems, which can happen when switching sides trying to peal off the cups. A month ago we switched sides 3-4 times successfully, then tried unsuccessfully 4 times to get the gate to stay put - finally giving up for the day. Prior to the next trip out I washed the cups with dish soap and cleaned the boat side. I made sure to washed my hands after suntan lotion, then made sure no one touched the cup face. We have not had any issues since. Happy surfing.
