Ouch!

That shot was featured in MBY a few years ago and, if I'm not mistaken, the shot of it nose diving in to the oggin was taken on a camera phone!

Cheers,

Well, if they verified also that the diesel engines were supercharged, I'd be really curious to hear more about them!

They didn't did they?
What they were verifying was the incident took place, as confirmed by Carver Yachts.

Oh dear. That is such as sad sight. Anyone know the size of the insurance claim. I'll make the first guess: £80k

Actually, in the webpage you linked, they seem to classify "True" the whole frame reported as an example, which includes the description.
And incidentally, the value reported in that example is much more realistic ($2.5m), but the engines remain supercharged.

Feel free to update the score, I'm not that interested.

thought so when I read it, was there ever a supercharged diesel engine on anything (let alone boat)

All two stroke diesels are supercharged, aka Detroits.
Also all opposed piston diesels, aka, Leyland L60 (Cheftain tank).
Also deltic diesels.
Also lister blackstone.
Marinised commer.
Plus quite a few other marine diesels, especially very large ships type.

The good news is that this particular pair can be considered very much water cooled....

slightly confused. Alf's (Divemaster) detroits are definitely turbocharged and not supercharged, just check the pics posted yesterday evening.

Am I missing something?
I understand supercharged as in Mad Max's car engine.

cheers

what are the two white patches on the keel??? stripped antifoul?

Unless I've been sold a pup there are a couple of superchargers bolted to the side of my D4's, and the KAD300's before that.

just checked some specs in the web and you are right, apologies.
These engines do have a supercharger for low revs that passes the load to a turbocharger once at 2700rpm or so.

Yes they can be either super or turbo charged. All they need is an air source that is pressured to push the exhaust gases through and out the outlet port, while also inputing new fresh air for combustion hence why some uncombusted fuel escapes.

Yep, indeed. Funny, I forgot the small Volvos in spite of the fact that I've had two boats with them (kad42 and kad43)...
...though they couldn't suit the above boat, obviously.

No, AFAIK sorry two stroke diesels cannot be purely turbo charged or how do you start them? You have to have exhaust gases whizzing round the turbos to get air blown into the cylinders, I have seen detroit v8's (in M107 and M109 self propelled howitzers) with both super and turbo chargers, but never seen a two stroke with turbo alone, mind you not seen all engines built!!
Just checked the photos mentioned, about diemasters detroits, that engine is indeed supercharged and turbo charged, if you look at the pictures, the outlet from the turbo, goes through an intercooler and into a plenum and then into a roots type supercharger.

Must need either a supercharger alone or both then
