limber hole

Limber holes are common in the bilges of wooden boats.

Limber holes are created in between bulkheads so that one compartment does not fill with water.

Limber holes perforate the wall of the box at the floor of each chamber.

Partitions may contain limber holes to allow water to flow at a controlled rate into lower compartments.

They have a different arrangement of limber holes on the outer hull than Akula Is.

These were not watertight, as centrally placed limber holes run through the floor for the drainage of the bilge.

A limber hole is a drain hole through a frame in a boat designed to prevent water from accumulating against one side of the frame.

The seas were crashing against the Delta, too, and he could see water splashing in and out of the limber holes that lined the boomer's flanks.

It is believed from evidence in wrecks that the limber holes could be stopped either to allow the carriage of liquid cargoes or to isolate a compartment that had sprung a leak.

New steel plates were welded to the bottom at the bows, limber holes were let through the forward frames, and the cable locker drain was repaired and re-routed to a new through-hull above the water line.

Due to the numerous foreign primary sources that hint to the existence of true watertight compartments in junks, historians such as Joseph Needham proposed that the limber holes were stopped up as noted above in case of leakage.

In 2007, using a ROV, DSSI/Oceaneering returned to the site, and took video recordings of the imploded remains of a submarine, one which had markings in English, and propeller guards and limber holes identical to those on the Grunion.

All wrecks discovered so far have limber holes; these are different from the free flooding holes that are located only in the foremost and aftermost compartments, but are at the base of the transverse bulkheads allowing water in each compartment to drain to the lowest compartment, thus facilitating pumping.
