I'm not sure what the rules are for the MuzzyClassic specifically, but at other tourneys that I've been to you can drop off fish as many times as you want as long as the containers are labelled or otherwise show ownership.

One of the strengths of the bigger boats is that they can handle more weight before having to drop off. Less trips to the dock mean more time fishing.Dropping off earlier can pay off too since it will bring your boat back to a shallower draft and giveyour poor motor a break.
