295-ft. (89.9-m) Mast to support 2,900 sq. Halmatic is manufacturing a 295-ft. (90-m) mast that will be fitted on the world's biggest sloop, currently under construction by its parent Vosper Thornycroft Shipbuilding, part of the VT Group. Mirabella V will be around 246 ft. (75 m) long and its mast will support some 2,900 sq. m. of sail. Halmatic will use its long-standing expertise in composite manufacture to produce the hollow carbon epoxy mast, which will have a maximum cross section of 1.5 m and structural thickness of up to 32 mm. The mast is manufactured in halves, with one comprising a complete length and the other divided into three sections. Framework for the mold will be made from MDF cut on VT's advanced laser cutting and profiling machine.
