For races where I do not to carry a bucket with a gamma lid I put my food under the stern deck in a Dryshed bag and wedge my big gear bag to block the opening.
A scented dryer sheet thrown over the food bag helps mask the food smell or at least makes the boat smell sexier. I also have my spray skirt on with he tunnel rolled and pined by clothes pins. I carry wood ones on my rudder cables behind the sliders.
The dryer sheets are also nice to stick in the foot of a sleeping bag for us stinky feet people.
The crows will rip you off at Flamingo if you leave something small that catches thier fancy, food or other stuff.
