In order to give greater carrying capacity and maximum speed than Vember, the Vember Expedition extends the length by 10% to 5.35m (17.53 feet), while maintaining the same beam and stability characteristics. The construction follows the Vember Build Manual, but with the transverse temporary forms spaced at 330mm rather than 300mm.
