I had some leaking into my starboard lazarette when I first bought the boat. It turns out the shore power cable wasn't allowing the cover to close all the way. I just train the cable up through the drain slot under the edge of the cover and it is dry as a popcorn fart now.
I did experience some other leakage in heavy weather right under the steering pedestal. All the control cables, electronic cables, etc are led through the pedestal through one hole into the aft stateroom. Water finds it's way through the pedestal and that hole for the cables. Not a problem at the marina when the canvas cover is on, but under way, it's a leaky area if it gets wet.
