Suggest taking the trailer to a scale.. then the boat and trailer. Do some some simple math. Only way is to lighten the boat or it's contents. Also, when you get the boat "lighter" May have more heel when sailing.
Adding a longer stern (sugar scoop) could help but then you would be getting into design issues.
