One bad weld, a bit of corrosion, a leak and it's "DIVE, DIVE, DIVE"
(In fact, I'm sure I've seen similar structures on submarines)

Simon P.,

No, these sponsons are air chambers only. The welding,from what I've seen and I am not a welder, appears to be deep penetration stuff, from both sides, with joints beveled before welding. They have been using a sort of redish paint like product in an aersol can to spray over the welds.Something to do about checking the welds? There is talk however of each water-tight chamber being tested with pressurized air for integrity.


Cheers!

Hi Michael,

They do have one bilge pump per water-tight compartment within the sponsons. Each pump is connected to a seperate pipe and leads aft,through watertight sponson bulkheads to exit through the transom of each sponson.

That is how it was set up, as we can see in this photo:





However, the most recent photos of the now closed and welded sponson transoms shows no exit hole for these pipes! I haven't a clue why this is so however it may have something to do with the fact that all these bilge drain pipes would exit bellow the originally drawn water line and the latest inspection tour may have put an end to that idea?






Also, with the very real need for these sponsons to be water-tight, would this not also make them somewhat air tight thus creating something of a problem for the bilge pumps as a vacuum would be created once the pumps attempted to pump any water out?

And yes, I suspect condensation will indeed be a major concern inside these structures considering our roller-coaster temperature swings


Cheers!

Hi TimH.,

That would be a prudent way to proceed however this particular boat exceeds both the capacity of the yards' own travel-lift and the travel-lifts' launching basin dimensions. Hence the custom made trailer upon which the boat rests.

There are no other travel-lifts anywhere near here which could handle this boat either so trailering her is out of the question.She sits too high anyway to pass under some key structures.(overpasses and bridges).

Which is one,of many, reasons why I really hope she floats and gets out of here.Otherwise, "we" get stuck with her. Talk about an albatross!


Cheers!

Albatross? What flavour is it then?
Flavour? It's no flavour, it's f*n albatross, bleedin' seabird flavoured!

anything new on this boat? I loved reading the entire thread...helped pass the time waiting for the computer to finish it's back-up yesterday.


BTW, what happens when they puncture one of those fancy looking sponsons... my guess is snap roll and DIVE DIVE DIVE

Nah. Someone just jumps over the other side and punctures the other one too. See, you don't have to make this complicated.

ok pick my self up off the floor and apresiate that Boat dude
flipping cracked me up big times with that one

snap role and dive dive

LMAO

I would expcet they are getting anxious to get this piece of garbage in the water. It is not warming up all that much and if they wait too long they will be launching onto ice.

Yeah. But at least on ice of sufficient thickness it would be stable. No roll problems, nosiree Bob! (couldn't help myself )

And the LWL would be easy to calculate, no surprises like on the first launch attempt.
