Aluminium

Aluminium is an extremely lightweight material and highly resistant to corrosion. Its softness means that it is of little use in boat construction, despite the obvious advantages of its weight. However, aluminium alloys are much stronger and are used commonly in the aircraft and nautical industries. Welding and riveting techniques have improved and hulls can be made out of large single sheets which are double-plated to increase solidity. Other equipment can also be in aluminium, such as seating, storage compartments and hatches.
