A Brief Introduction To The Aft Peak.

The aft peak is the cabin under the last watertight bulkhead in the stern of the ship, the bulkhead deck or the deck below deck. The aft peak is mainly used as ballast water tank or fresh water tank to adjust the floating state of the ship. The aft peak tank is relatively small, usually as the stern ballast tank, which is combined with the first peak tank to regulate the trim of the hull. The aft peak of the bulk freighter is sometimes used to hold the silos. In case of special circumstances, the aft peak can also be used for temporary shelters.

After the last watertight bulkhead on the stern of the ship, the cabin below the bulkhead deck or the watertight platform deck. Because the stern is equipped with propeller and rudder, the force is complex, vibration is large, its structure needs to be strengthened, mostly adopt transverse frame type. Its frame spacing is small; The floor of the bottom of the vessel is provided with a ribbed plate and raised to a height above the stern tube. A middle keel or middle girder on the floor; Strengthened peak ribs on the side; A strong chest beam with a certain distance between the top of the floor and the side longitudinal girder; The structure of the tail column or shaft sleeve, rudder arm and pipe should be strengthened accordingly. The tail of the cruisers and the overhanging part of the elliptical tail are often used with a fan inclined ribs and oblique beams to effectively connect the outer plates of the arc. When the aft peak tank is used as ballast tank or fresh water tank, it shall be equipped with a swinging bulkhead to reduce the impact of the liquid on the hull and the stability of the ship. Ships sailing in the ice area should be strengthened in the ice area. The length of the end peak of the single-oar vessel should be in the hold of the stern tube; If the double oar vessel is required, the bulkhead of the aft peak bulkhead is too much forward, so it depends on the tail-type line, construction condition and the required capacity.

The last cabin on the rear end of the wooden junk. The upper part of the aft deck, the bilge and the rear wall are the rear honing board and the broken water beam. Generally used for storage of sundry goods, some of which are also for crew quarters or crew modules.
