Abstract
Expanded plastic objects are formed by applying the foamed material to one or more hollow objects. Preferably: the hollow object is completely surrounded by foamed plastic; hollow object is of flexible material internally pressurised with gas. Typically, a boat hull is formed of inflatable flexible cells, externally coated with hard foamed plastic.
