Boats, ships and vessels do not collapse, they capsize. If they sink to depth with a enough air retained inside they may implode, but this more common in movies than in real life.
When a vessel capsizes, one of three things happens. It simply rolls over and the hulls sticks out of the water. The vessel partially submerges and the remaining air partially floats the vessel or it sinks to the bottom, depending on the depth of water.
A boat collapses when the engine is not functioning well.
Collapses? Don't know what you mean by that but if you mean flips over, it's called "capsizing". I hope it helped. If not, elaborate a bit more and I'll see what I can do. Ch33rs

There's no mass range that's between "collapses into a neutron star or pulsar" and "collapses into a black hole". It'll be one or the other.

The collapses star gets squeezed by collapses gas and turns into a black hole.
A Headland is formed

Yes, if the star is massive enough when the core collapses a supernova explosion happens.
The can collapses and closes in on itself.
