"Kahu" Refloating

[MILLIE BOO TOO]

Wow what a state. Very interesting how they refloat sunken boats.

Please no more emotional outbursts from the usual suspects, it would be a good idea to keep that to the previous thread on this sad episode.

Looks like they labelled them on Youtube the wrong way round to the titles, this shows the bit before:

She's just been floated into Saxon Wharf tonight to be lifted. Going over tomorrow to have a peek

 

[aquapower]

Why go to Saxon Wharf via Portsmouth ?

 

[itchenseadog]

Mentioning no names, but I heard that the people who originally craned the boat out (they owned the only available floating crane in the area that had the lift capacity and were based in Portsmouth) thought they could name any price to cut the wreck up. The insurance rep subsequently "sold" the wreck to a Southampton concern who will be using the basically sound hull for conversion to a houseboat.

a terrible state at Saxon today. The insides have just ended up in a pile in the hull . How anyone is going to convert this will be amazing, Heard its only going to be at Saxon for 6 weeks

Yes so true, I saw the mess sitting there yesterday morning. Very sad to see it. I was going to take a piccy but thought it was a bit too morbid. The boat was lifted and then floated over on a Bladerunner I was told and then had to be relifted onto a barge to get her to Saxon /wharf.

Extra expense all the way. Kahu was at Saxon in June, probably why was minimal fouling but loads of mud right up the stabilizer wings. Thay had also flame cut through the bow thruster props to make room for the bow lifting strap. Quite a project, getting her up again.

...The boat was lifted and then floated over on a Bladerunner I was told and then had to be relifted onto a barge to get her to Saxon /wharf...

She never went on a Bladerunner, she went straight onto the barge in Cowes which took her to Portsmouth.

 

[itchenseadog]

When it was decided she would go to Saxon Wharf she had to be transhipped on to a narrower barge that would fit between the piers of the Saxon lift dock

Down there yesterday, very sad sight.

 

[lisilou]

Yup..very sad

Have the engines been removed? I'd guess not as both shafts and props seem to be there. Or maybe they are also considered to be totally written off.

 

[MapisM]

Waddumean "both"? Can't see why they should have fitted a second engine/shaft/prop after refloating the thing...

Main and wing. That's my get out!

 

[MapisM]

Haha, funny you mention it, 'cause I did wonder what sort of wing engine the boat had.
I can't see one in the pics, but I suppose she must have had some sort of get home system.
Maybe an electric motor coupled to the main shaft?
I've seen a few of these solutions, though never on Nordhavns...

 

[Firefly625]

most single engines Nordhavns have a wing engine, normally something circa 30hp, often Yanmar, nice thing about Nordhavn they do things properly, the wing engine is totally seperate, so own starting battery, shaft etc, and it operates off separate fuel supply. Their aim is in the event of a total engine or drivetrain failure, the wing engine gives 5 knots propulsion in calm seas..

 

[MapisM]

nice thing about Nordhavn they do things properly

Well, this pretty much depends on where you set the "properly" bar.
If it's survival in every conceivable event that you're after, then there are steel trawlers where the wing engine is also located in a utility room, separated by the main e/r through a fire and waterproof door.
Aside from having everything else separate, as you point out, this solution grants that the wing engine can still run even in the event that the main e/r is completely disabled by a catastrophic fire, and possibly also flooded.
I've never seen that in any Nordhavn.
Of course, being built in grp, a Nordhavn is unlikely to stay afloat in the event of a catastrophic e/r fire anyway, so I suppose they might argue that such layout would be pointless...

Kahu was for sale with Ancasta and,according to their details,she was powered with a main DD @535hp plus a Lugger wing engine .

Main and wing engine plus generator/s all completely written off. Nothing left except lumps of scrap metal and skip loads of sodden burnt mat

As I understand, you posted this in reply to my "never on Nordhavns" comment, but actually I was referring to the rather peculiar solution of an electric motor, powered by a big genset and coupled to the main shaft.
A wing small diesel with its own (sometimes foldable) prop is indeed more common, and afaik it's what they fit on single screw Nordhavns.
I was just wondering because I didn't spot a secondary prop in the above pics....
