I asked in a post on another forum if it might be prudent, or a viable plan/option, to have all personnel topside with PFD's on - as miserable as it might be - to avoid the potential of being trapped below in a capsizing/sinking. A responder said it would be better to have 'non essential' people go below with the cabin secured.
Then I read this in the FWYC newsletter:
The Cal 24 the trio were racing on had broached, turtled and sunk. Two other crew members that had gone below to put on their lifejackets had been trapped in the cabin when it sank...and (topside crew) recounted seeing their two fellow crew members float to the surface, lifejackets on, but they were non-responsive with no pulse.
Now, certainly the type and size of the boat, and how well the cabin can be sealed, are important variables. But, I can't help but wonder again if having everyone topside is something to consider.
