Cool new boat that was designed by Mike Howe from Howe2Live who just did the New York to Miami run in his MTI.
52’ with quad 600s, currently running 65 mph with and estimated top speed of 80.

Where are you seeing the current and top speeds? Everything I saw looks to be renderings?

I’ll Take twin diesels with direct drives. Fuckin outboards on that thing. 🙄🤦‍♂️
The negative I cant help but wonder about……… How will those small props work when reversing and maneuvering the boat in tight docking situations. Yikes!

Sure, they get all the bite in the world on their typical application, but a 40,000lb plus, boat, is a whole different beast.

Exactly! Everyone’s all in love with outboards. I actually don’t see the positive of throwing them on this boat as all except top speed. They won’t be any more fuel efficient (probably less). They’ll be less reliable for sure, not to mention they hang off the back and take up some nice realestate that could be used for a great dive platform and tended storage.

People gone a little overboard on the whole outboard thing. And the more they do the less I find them attractive. Just my .02 though.

I dig the boat and the layout. Very cool. Just would do it with diesels.

I think a boat like this opens up a lot more freedom of exploration. The amount of distance you could cover cruising at 50 knots vs 10 knots speaks for its self. Let’s say someone living in Miami had a 3 day weekend and they wanted to cruise to the Bahamas and island hop, which power choice would be better?

I personally think it’s a really cool idea, especially for the kind of boating I would like to do if I found myself with a couple more zeros in my bank account.

I have no experience docking anything that weighs more than 6k pounds but when the outboard boat has 8 props would it still get its ass kicked by two direct drives?

Personally, again I’d rather have the diesels. Just did the Bahamas via quad outboard Cc a couple weeks ago. Had to get fuel twice while running around and on the west end of the island, they run out! With dieslels and large fuel capacity you could fuel up in Miami and depending on what you’re doing get over, explore and back without getting fuel in Bahamas. Draft wouldn’t be too much different.

I just think outboards are the trend and everyone jumping on the band wagon. These big ass cruisers I don’t personally think it’s a good idea. Just don’t see the benifit.

The diesels motors compared to 2400hp of outboards wouldn’t even be close in fuel mileage. At any planning speed, the outboards will be going through hundreds of gallons per hour. All while beating the shit out of the interior of the boat.

Another fun factor…….. It might be a good idea to use seatbelts while going at speed, while up on the flybridge. I can see people getting pitched off that, in a turn.

I like catamaran too. However, this is the last type of boat I would put outboards on. It’s just too big.

I think the distance covered would still be way ahead on the OB even with fuel stops, I still would love to have a diesel power cat when I’m retired to cruise. However if it was extended weekend trips I think the OB boat would allow a lot more freedom.

8 props don’t mean shit. It’s the size that matters.

Big boats need big wheels. The direct drives are the way to go. Instant gratification.

A set of turbo diesels could push that thing to 40-50mph. It ain’t 80 but Bimini is only 40 miles from Miami. 😁👍

If the Speed threads have taught me anything is that you're not allowed to have an opinion if you're not buying. So I'll just keep looking at the pictures and decide if I want one or not.

I feel bad for not giving a longer explanation. I had a lot going on.

Here is a little more. Big boats have increasing inertia. This means the heavier they are, The harder it is to reverse their momentum. The larger the prop, the more bite it has at low speeds. 2 large direct drive props will have a lot more control than 8 small outboard props. They just can’t overcome the momentum created.

The outboards also do not have the transmissions of a diesel boat. A diesel can be thrown forward to reverse, reverse to forward, or what ever combo, at will. No repercussions. An outboards gear box cannot handle those quick in and out of gear changes. Especially going quickly from forward to reverse, or reverse to forward. It’s the same reason why you don’t do that to a Bravo drive. You always should stop at neutral, before putting it forward or reverse, if you want to get the longest life out of it. Diesels are not like that.

Diesels also get thousands of hours more out of the life of a motor than an outboard. Thousands!

I'm also thinking a pair of 1000-1200 Hp Cat or MTU's with direct drives probably cost less than the four OB's.

It looks like a nice boat. The arguments about power make sense, not every boat needs a couple thousand expensive HP hanging in the water.

It's a bit depressing to see the builder doesn't even know how to spell gunwale. From the video:

Dual Side Gunnel Doors

I prefer the original version and its 700 year old history.

😁

These folks care about flash & look at me for their YouTube & other social media bullshit. The outboards will probably run 80+ mph. I'd also prefer big diesels but there's zero wow factor cruising 40mph with diesels.

Just wanted to point out that the 600 Merc outboards actually do have a 2-speed ZF automatic transmission with shift strategies to support them, and the drives can vector the thrust in joystick mode, very maneuverable.


Check it out sometime, a lot of development went into that system for Merc to enter that market.

I’m not saying outboards for everything, but people sure seem to be putting them on everything, so there must be an appeal or advantage somewhere for them.

Profits for the mfgs and regaining market share they were losing to aftermarket companies.

All proprietary parts that can only be sourced from merc for the time being, and they have also been very heavy handed going after people who are trying to modify the motors.

I'm starting to think this outboard mania came about due to all the older offshore guys being so deaf they can't hear & appreciate the big thump thump I/Os anymore... must be some kinda maturation bullshit combined with needing to hear their wives beautiful voices 😆

Here is a thread hijack……… lol

Approx 250 yards from my home, they have started building Jimmy Buffetts new catamaran. It’s a 56’ with outboards being built by Merritt Yachts. Merritt also customized his 42’ Freeman, by adding a pilot house. Merritt builds mainly high end sportfishers. A typical Merritt does not have any Merritt emblems. You have to know what to look for, since it has many identifiers.

It appears that the 56’ Catamaran will be powered by quad outboards.

As a side note, 3 years ago, while I was at the gas dock with a commercial boat I was Captaining, I guy boated to the scales right next to the gas dock. He had an approx 700lb Marlin that he had just caught. My deckhand and I walked over to see it. Little did we realize that Jimmy Buffett had pulled up to gas dock with his Freeman, and a friend. For the next half hour, the 4 of us chatted up the Marlin and other fun stories. It was pretty cool. He also showed us his Freeman.

Anyways, here’s the sketch of the boat on Instagram.


Here is a pic of the hull mold and top cap mold.

Quad 600s? Lame.

Our all-new premier flagship, the 67 LX Series, is being designed in partnership with world renowned super yacht design studio Harrison Eidsgaard. One of the largest outboard-powered sportfishing yachts to be built in the world, it will encompass three unique models: the 670 LXF (Luxury Fish Model); the 670 LXS (Luxury Sport Model); and the 670 LXC (Luxury Cruiser Model).

All three 67 LX Series versions will be powered with five (5) Mercury V-12 600 HP engines, producing 3,000 HP and a projected top speed of 60 MPH, a fast cruise of 40 MPH, and a range of approximately 500 miles.

To hear Steve Potts Jr. tell it, the 670 simply would not have been possible several years ago. Ultimately the decision to tackle such a huge, beachable mini-mega yacht really revolved around engines like Mercury’s 600.

You simply couldn’t build a boat with these capabilities and dimensions with an inboard motor. The propeller shaft would have to come in at too steep an angle to allow for a planned low, flat fold-down stern and the engine room would be way too cramped.

Having steerable lower units allows for the Mercurys to be spaced closely together too—permitting a reasonably narrow beam (in this case 19 feet). It’s also, Potts pointed out simply a lot easier to service a motor hanging off the back. “It wasn’t that long ago that you the biggest outboard was a 225,” he said. “The 600’s are proven engines. The transom’s only so wide—so you can get them a lot tighter and closer together. You gotta be able to trailer it down the road too.”

I can answer all your questions about the DSK Kraken as I spent the past two weeks running this incredible boat from Miami to the Bahamas and from Pompano Beach, Florida all the way to Connecticut in less than SEVEN DAYS!! Below is the second video which has links to three others at the end of this video.

It was simply insane!! We were in the Norfolk channel, I noticed the USCG trying to pass me, "Oh Hell NO!!!" For a moment, I just knew I was going to get stopped and boarded... then I saw they all had their phones up taking pics/video!!

I noticed at ~45mph it was burning ~110-120gph. What speed is it most efficient at?

Such an awesome boat.

The best efficiency is 32-43mph... at that speed it is netting 0.45-0.57 mpg with a fuel burn ranging 56-95gph. When the conditions whip up, its actually better to add some speed up to 45-50mph where you will see fuel consumption between 105-120gph or 0.41-0.42mpg. Understand the difference between traveling 100 miles at 32mph and 50mph is a fuel savings not burning for the additional 18 minutes of run time the additional the cost of three gallons of fuel. Compare this to my 52' Sunseeker with twin Volvo-Penta IPS900 diesels burning 85gph at 28-30 knots and requiring new fuel filters every 500 miles at a cost of $1000!!

Thats an interesting comparison to the twin diesels! I never knew the filters were that expensive for one of those, thats nuts!!! 2$ a mile!

To be honest, there's usually not much wrong with the filters, it takes three different ones for each engine. There's one on the tank for the low pressure to the engine and two on each engine. So two tanks, port & starboard and twin engines. Making the trip each season from Rochester, NY to Florida and back cruising 25-30mph takes a while. The Volvo-Penta IPS engine systems/sensors are stupid-sensitive, and always throwing an erroneous code for something that really isn't happening... which always shuts something down or limps along until you reset it. Then I am forgetting the IPS Pod Drive systems have their own oil filters as well.
