Peak tanks. Distinction is made between the forepeak tank and aft peak tank.
The forepeak is the space between the stem and the collision bulkhead. The distance between the stem and the collision bulkhead must be at least 5 per cent of the ships’s length and not more than 8 per cent. The forepeak tank is the part of the forepeak up to the deck. The after peak tank occupies the space between the stern and the afterpeak tank bulkhead. Both peak tanks may be used for fresh water or ballast.
