It would be cozy but 11 wouldn't be hard I reckon, they are a fair sized bit of kit.
5 in that cabin on other hand would be hard to get out of if you were dressed for cold and with a LJ on.
Sad, so sad.

I wouldn't necessarily assume the five fatalities were in the cabin. They'd just have to be trapped under the boat (cockpit) once it had turned over. Good chance the survivors were thrown clear when it rolled. Obviously being in the cabin means you aren't going to be thrown clear. That and the cold shock.
Assuming the average weight of twitchers was 80 kg, 10 twitchers, 800 kg. Centre of mass at 1.5 m above the deck. What does a boat like that weigh? 1,600kg? I don't know enough about form stability of boats to know how much force you'd need to tip one over. But I do wonder if they all ran to one side and it went ca-plop.

Nephew has the 1850 super cab and it is just a fishing platform.Most uncomfortable ride,totally crap unless flat calm,in sw 15 knot middle of the firth be lucky to do more than 8/10 knts. |

So latest witness reports saying a whale breached under the boat, capsizing it. Sounds a rare but plausible event. And difficult to avoid tragedy with even more layers of legislation.

Look at the number of yachts that have had a coming together with whales, there's been a fair few over the years.
Chatting do NZ's leading Whale biopsy taker, they are building an impressive data base of genetic etc, he said whales can't generally hear yachts sailing or stationary craft and told me that whenever I'm in the deep blue and quiet then suspect whales maybe around to turn the depth sounder on as the whales can detect the pings or tap the hull a bit to alert the wildlife they aren't alone. I thought that was very interesting.
If he's right, and I have more to believe it is than he isn't, if the photographers boat was stopped engine off a breaching whale probably just did not know it was there. They start the breach quite deep to get inertia to get their many tonnes out of the water so the whale may have been in full upward mode and did see it but too late.
I wonder if the concentrated into a smallish area use of the many boats and aircraft used for whale watching had any input? Just thinking maybe the Whale heard the boat but has been trained to ignore the noise as semi-constant background one. We'll never know but it would be interesting if we could.

Yes the depth sounder thing has been around for a while. In the old days when we had those old spinning units you switched on just for a depth reading, then switched off, there were (apparently) more whale strikes, proportionally.
Nowadays we mostly all have connected instrument systems that have speed / depth constantly running even in the open ocean. Resulting in fewer whale strikes, apparently.
I’d have though that charter boat would still have had either a depth sounder or even a fish finder running, even if engines off?
