This was a VIOLENT explosion, typical of a propane tank explosion. I believe propane is ODORLESS, therefore it could've already leaked into sleep compartments below.. Remnants of boat are torn apart, ripped apart from explosion. 34 dead on a 75 ft. boat merely 60 feet from shore is shocking. Perhaps the 34 were rendered unconscious from the lateral shock wave and the crew above were able to jump ship.

Prayers for victims families.

Commercial propane is NOT odorless. The manufactures add chemicals to it like they do with natural gas.

Propane itself is odorless, but the propane sold commercially normally has a chemical added to it so it has a distinct smell. That said I don't know if the smell would awaken you from you sleep.

It does tend to pool at low points, displacing the air under it. In that situation the result is usually a flash fire more than an explosion, but some mixing with air is all it takes to turn that situation into an explosion.

I believe propane is ODORLESS,

True; but the stuff they mix with it ain't. It's mixed in just SO we can detect it by smell.

No, you can smell it.
