KTBA Covert Shores
The latest KTBA chariot is a development of earlier models. The Mk.I and Mk.II are twin seat affairs with externally mounted diver propulsion devices. The larger -III and -IV versions have twin in-built propulsors on the rear hydroplane and can carry 3-4 combat divers at 3-4kts submerged. All designs are easily recognised by the distinctive bow fairing with shark-gills and upright windscreen (often without glass). Materials are predominantly fibreglass.
