What if the boat turns turtle?
sp. "buoyant", "detachable" |
|
| |
//Isn't this a lifeboat?// Carley float. |
|
| |
Depending on the size of the boat/ship and the sea stte this may be worse than being in separate lifeboats or on floats. Some form of hydrostatic release should be used or the first good wave to break green over the boat will take the roof off. |
|
| |
If the roof is held on by gravity, rough seas could make it move and while it may not come off the movement may cause damage to the rest of the boat. |
|
| |
If it is held on by a catch then this would have to be released which could cause a problem if the release fails. |
|
| |
Finally, what advantage does this have over lifeboats. It seams to create a 'all eggs in one basket' situation |
|
| |
It begs the question, why not an insubmersible boat? |
|
| |
Baked, RNLI (coastguard) boats are self-righting if they are capsized. |
|
| |
I will remind you that boats were formerly made entirely of insubmersible and detachable materials (i.e., wood). People still went down with their ships. |
|
| |
The boat itself has to be insubmersible, or you get sucked down in its wake when the boat sinks. (This is why you are advised to swim well away from a sinking ship when it's going down.) |
|
| |
So, you're basically putting a boat with no ballast on top of a boat. Or within a boat. Either way, you're building a liferaft, just on a grand scale. |
