- Hammer Yachts is the first power-catamaran builder to install a set of COX diesel outboard engines. The legendary range / efficiency of the HammerCat 35 is further enhanced with these outboard diesel. Range at 25 knots is ~750m. Video by @retroyspective
incredible!
wow!
Impressive. Any more video's and/or review of this boat and those diesels??
so far this is the only one, thank you for your compliment
Beautiful boat Peter, what are advantages with the Cox diesels over Yamaha? Any marine head options?
The standard engines on the HammerCat 35 are Suzuki 350's dual prop, great horsepower to weight ratio.
The advantage of Cox diesel engines is the increased efficiency (15-20%) and the fact that if one uses the HammerCat as a tender of a superyacht (as is the case with this HammerCat with Cox diesels), the mothership can very easily refill the diesel tanks on the tender and there is no need to store (flammable) gas on the mothership (if that is even allowed).
The HammerCat 35 has a very nice head / toilet in the center console cuddy, it is electric & fresh water flushing, so no nasty smells. Please contact us for more information.
How many hours after the first year? Any issues?
Are the engine blocks of cast iron on those diesels?
All aluminum.
How are those Diesel engines at say steady 8-12 knots and no wake idle with long low engine running slow speed and fouling?
You state that they are EPA compliant what kind of a farter is used and does the engine foul running at idle speeds for long distances?
Hi Paul, as far as we know you can run long times at idle speeds, but I have asked COX just to be sure. What I know is that Diesel Engines like to run 'under load' and the manual states that every now and then you should put the hammer down (pun intended) and run the engines WOT. What do you mean by 'what kind of a farter is used'?
Beautiful boat. You claim this to be a sea trial. How does the fuel burn & range compare to the standard 350 gas options ?
Cox diesel engines are 20-25% more efficient compared to the standard 350 gas engines
1500 rpm - 10 knots - 3 gph
2000 rpm - 16 knots - 5 gph
2500 rpm - 22 knots - 7 gph
3000 rpm - 26 knots - 11 gph
3750 rpm - 40 knots - 18 gph
Why would you not give fuel burn? That should be your main selling point....
1500 rpm - 10 knots - 3 gph
2000 rpm - 16 knots - 5 gph
2500 rpm - 22 knots - 7 gph
3000 rpm - 26 knots - 11 gph
3750 rpm - 40 knots - 18 gph
Being they are 25% more efficient than gas engines, are they more expensive to purchase??
Yes, the COX diesel outboards are quite expensive / double the price of our standard engines
@@hammeryachts5838 Aah. There go the savings then. And their market. If they were only marginally more expensive they could steal a bunch of market share but at that price, very few will make the switch. Large yacht owners only because of convenience. That's a shame. Combining the Hammer weight/efficiency with the diesel 25% efficiency could have been a serious game changing paradigm. Oh well back to Mercury for my future boat.
It's either Hammercat, insetta or invincible for my dream boat purchase next year. Love the Hammercat for efficiency and thinking outside the box. Insetta for styling and design features and ease of maintenance. The invincible has a bit of both. Tough decision.........
🌟🌟🌟🌟💫💫💫👍👍👍👍💪💪🙏🙏🙏🙏🙏🙏
I dont understand why you dont show the most important part... fuel burn at all rpm!
1500 rpm - 10 knots - 3 gph
2000 rpm - 16 knots - 5 gph
2500 rpm - 22 knots - 7 gph
3000 rpm - 26 knots - 11 gph
3750 rpm - 40 knots - 18 gph
@@hammeryachts5838 Is that total or per engine?
@@SlipItIn.Fishing that is total fuel consumption for both engines
