Mac Boats are formed in a sophisticated moulding process which creates a one-piece polyethylene hull. In addition to inherent strength which is five times that of fibreglass, polyethylene Mac Boats are virtually maintenance free. They will never suffer from corrosion, rust, rot, osmosis, mould or electrolysis and there is no paintwork to maintain or gelcoat to polish. In addition, polyethylene is impervious to corrosive liquids such as battery acid, and petrol as well as UV light.
