This Sunseeker provides the means of escape for The Cigar Girl in the pre-title sequence. After shooting at Bond through a hole in the wall of MI6 from the Sunseeker based on the Thames, Bond decides to make pursuit in the Q-Boat.
With powerful engines and armed with a deck mounted machinegun, and mortar/grenade handheld launcher, the Sunseeker packs an aggressive punch. The Sunseeker meets its end however when Bond fires dual heat-seeking torpedoes directly at it, causing The Cigar Girl to abandon ship and steal a hot-air balloon instead. §
