Anyone not yet seen the slide show of Paul Allen's yacht "Octopus"?
If you haven't, check this thing out. The world's largest private yacht at 416'. Crew of 60. The thing has 7 tenders including the main tender, which is 63ft. long. Not only does it have two helicoptors with pads fore and aft, but it has a hangar that holds them both. Did I mention the submarine that holds 10?
