Jesus Christ those things are huge. I could remove an outdrive and lay it on the floor or on a wood stand. I could pull the engine and set it on some wood blocks. Where do you put that 600 after you rent a overhead crane to remove it ? That isn't the easy to work on outboard everyone has in mind.

Idk about more efficient. Our stepped bottom 477 Intrepid with 4 425 Yamahas would get about .5 mpg at a 45mph cruise and our 80,000lb Pershing with two 1625hp MTU’s and surface drives would get about .35mpg at 45mph cruise. With that being said I would be willing to bet two 1500hp Man with surfaces drives in a 60ft stepped bottom intrepid would get over .5mpg. I’m going to bet the 4 600 Mercs won’t be able to match that.

When we ran some big OB powered boats after owning the Pershing we actually commented a bunch of times how much bigger/heavier the Pershing was and at equal speeds wasn’t burning much more fuel…

Another thing when boats start getting to 60ft is your marina choices really narrow down and you get into the mind set of throwing anchor and pulling the tender out of the trunk. Unless they get creative with a trunk out of the side of the boat or something, there’s no way to put a tender into one of these big OB boats.

You will want to idle and reverse the diesels, and maybe even have 2 speeds forward given their limited rpm range. All of a sudden, you have added the complexity of a shiftable transmission.

The beauty of outboards is that they are manufactured as standard products at industrial scale. You just cannot beat that for cost and quality. Like building a car versus building a house.

The "jumbo CC" market is odd. They need huge HP to make them fast but now they need a ton of fuel aboard to feed the thirsty motors, more speed/more fuel, now we need more motors which means more fuel!

HCB has a dealership in town, I've seen every model being sea trialed. After the wow factor seeing one at the dock you start thinking, why would you want that thing? A 53-65 ft CC is everything a CC doesn't want to be (its no longer a wash it out, flush the motors and walk away type boat). Now add the 3mm price tag and suddenly you open your eyes to other options!

Me? 34-39 CC with twins/triples at most is perfect. Keep it simple, use it more!

The appeal is that it has extended service intervals and can be serviced from the boat.

I agree, for 3 mm you could have a badass Pershing and a brand new nortech. I don’t understand these giant day boats

They are selling so good for them.

As for the ease of ownership, anytime you get 4,5,6 motors and miles of vinyl and bling.
Then add 20 of you best drunk friends, doesn't mean just because its a "CC" its easy to take care of and clean. But I doubt anybody that owns something like that will be doing the cleaning and maintenance anyway.

I saw a pic of the Intrepid 60 on Instragram this morning, but now I can't find it again.

This is the 65' HCB Estrella with 6, 600HP V12s.
$5M

That's the Jupiter lighthouse in the background............5mm is insanity for a CC!

Do the DelaTorre brothers still own HCB? They were a huge boat dealer for Hydrasport (and multiple Apache owners) then bought Hydrasport and morphed it into luxury CC's and changed the name to HCB (Hydrasport Custom Boats).
