Should vessels that are abandoned mid-voyage be scuttled?

Didn't realise you had alergies?

I think I may have messed up reply and edit. A sort of mixtamepostes

That was just a temporary measure while he fixed his mast head light from the dinghy. You can see him in the cockpit as he works the Whale Gusher

It's only a guess, but i think that cutting hoses on a sinking boat is kinda pointless.......

The point is that one sound hull of a multihull may well support a sunken hull if the hatches remain above water level when the boat is at, say 45 degrees. The damaged hull may well have a certain amount of air trapped & with the other hull still floating it may not tip the wreck to a full 90 degrees. It depends on the design of the boat. ie taken to its extreme-A caravan is different to a Warram

Colour me unconvinced. Water weighs a lot.

But I don't know, really.

Water in water (of same type ie fresh-fresh)weighs nothing until you want to displace it
Immerse a bucket of water in a pond & the weight you get is that of the bucket ( adjusted for specific gravity of the bucket)

Most multis are designed to be ‘unsinkable’, ie there is buoyancy built in to the structure. Usually collision bulkheads forward double up, ie hitting a container might breach that but the rest of the boat is undamaged. If the rst of the boat floods, as long asylu haven’t hit a container as well, you still float. There will be several in each hull, and in many cases voids are filled with closed cell foam, in addition to foam or balsa core construction. Unless theres catastrophic damage, ours floats with about waist deep water in the cabin I believe. I think opening a seacock makes no difference to that. To make sure there’s not enough left to be a hazard, maybe some diesel and a flare?

Put a bucket in water. Fill it until the bucket becomes negatively buoyant. It sinks.

I shouldn't think that many boats are stuffed full of (heavy) buckets. A bucket of water in the sea weighs nothing. I thought you might realise that already.

 

[Wandering Star]

Could I ask that anyone considering scuttling their boat fitted with ST30 winches, removes them first and gives them to me after the ordeal is over as I’d like a pair but can’t afford to replace my current non self trailers. Also would appreciate if you’d keep them dry in the meantime.

Here are some pics of the Gunboat 55 Rainmaker that I took at a yard in Bermuda when I stopped there on a delivery of a bigger Gunboat.

Rainmaker was abandoned on her maiden voyage just off the Carolinas in the USA.

She was recovered about 2 years later by someone out fishing off Bermuda, and I believe is now a power cat in the UK.

Given that she was abandoned just near the NE flowing gulf stream, it seem likely that she drifted NE, and then E pretty far in the Atlantic, and then S enough to get into the easterlies, before ending up in Bermuda.

Not sure of your point here. I don't think any boats are stuffed full of heavy buckets. What I do know is that a bucket lost over the side of a yacht generally sinks. Because it becomes negatively buoyant. Its good to know this if any9ne tries the old fender and bucket thing for mob. When the handle eventually comes off the bucket, it sinks.

I wonder if the boat lost its rig and therefore a lot of weight? Wonder why anyone would put time, effort and money into refitting that?

it had a carbon mast, which came down in a squall.

that was the reason for the abandonment.

my guess is it would float even with the rig

the restored boat is a power cat - so no rig.

However, if it was a double walled ice bucket, it would float even if full of water. Deep, maybe, but definitely float.

But IIRC, the ice bucket challenge ended up with no ice in the bucket?

(Sorry, I couldn't resist. I'll get my coat and flounce for at least ice minutes)

It's a bit complicated, I suppose. Weight, mass, buoyancy, sea state, free surface area of flooded spaces, yadda yadda. Its difficult to find anything definitive online.

But when I've been sat on watch on catamarans in the middle of the night in the middle of the Atlantic, its not something that's troubled me. You always get someone though who asks ' how often do these things flip over? ' Stock reply is 'just the once'.

My mate did the honourable thing when he abandoned his Vertue on the way back from the Azores. 25ft of lovely wood didn't float long with the sounder pulled. She was filling up already mind! There were at least 3 buckets on board if I remember correctly but I can't guarantee the density of the plastic they were made of.

While I agree that leaving a shipping hazard borders on the criminal....going below in desperate circumstances could be risky.....what if you get trapped or injured ?.....as captain you are the most competent person aboard which means that you have a duty to those in the liferaft as they may not be able to survive without you.

Depends what the bucket itself is made of. A metal,bucket sinks, some plastic ones float. It depends on the density of the bucket material. The water weight is irrelevant

By the logic of some here, wood floats .........
