___ are openings in the support frame (floors) of a lifeboat and allow water in the bilge to flow from one compartment to the next so water can drain while out of the water/stowed.

Limber holes are openings in the floors’ support frames of a lifeboat that connect bilge spaces between compartments. They let water trapped in one section flow into the next, moving it toward the lowest point so it can be drained or pumped out, even when the boat isn’t in the water and is stowed. This ensures water doesn’t accumulate in a single compartment, which helps maintain buoyancy and stability.

Weep holes, by contrast, are small openings meant to relieve moisture or minor leakage from structure layers but aren’t used to transfer bilge water between compartments. Scuppers drain water off the deck to the exterior, not between interior compartments. Hatches are entry/exit openings and don’t serve the purpose of moving bilge water from one compartment to another.
