Leeward cockpit seat would collect a pool of water. Never got too big, though. If it got too big, it just drained into the locker & then into the bilge. That boat only had one dry locker - the one hanging under the cockpit. All the other low lockers were subject to slosh. I still remember one two day race where the leftover morning donuts got put into the wrong locker. The box and the donuts dissolved and distributed themselves over the entire lower interior. What a mess!
