I'm not so sure he's too far off . On the high side for sure , but ......
Anyone built a 1000 hp twin turbo motor lately . Not cheap I'd say and not to mention that they probably used the same hull as the V-drives so you absolulty will not find a better built hull . River tunnel's are harder to come by than the River cruiser . I have a better idea . Call Schiada and have them give you a price to replicate this rig . Can you say mortgage ? It's worth some money for sure but definalty not 40k . Top notch none the less .
