 The Australian AMD catamaran design may mean as much as a 50% reduction in vessel speed penalty in high sea conditions (in which monohulls may only perform at half or less of their maximum capability).Further, seasickness and disorientation is significantly reduced, improving the combat readiness/situational awareness of the small-craft operators during such conditions.The polygonal-designed superstructure with its similarly angled gun mount indicates a reduced radar cross-section, although probably not enough to be a full stealth-ship as it is built from aluminium rather than composites, and also has a lot of reflective "clutter" in form of rails, searchlights and launchers on the deck.
