When I haul I tell the yard to deliberately block so she trims slightly down by the stern, which on my boat collects water in the bilge near the center where the pump is located.
I was told years ago that an experienced yard always blocks a boat with the bow raised slightly. Raising the stern can cause issues with raw-water cooling backflowing into the engine.
At my first haul out, with the bow raised higher than the afloat level, a leaking deck fill plate near the bow caused water to run under the starboard setee and all the cabinetry to exit and collect on the galley sole. Took me a while to hunt down that leak.
