I would hate to be the cox’n of that lifeboat as the ships moved apart.
Guess who is to blame for that.
If the boats had been tethered together there was every bit as much chance of the smaller boat capsizing. At sea transfers are risky at 10 knots more so because of too many uncontrollable factors. I wasn't a Coxun but I worked boat crew { as engineman} on 50' UB's and 35' PB's for the ship while deployed when we entered ports. I about bought the farm once from a swell when we were tied to a deck house and the ship anchored.
This was one of the reasons when that cruise ship went D.I,W. last year off Cali/Mexico coast they had the passenger stay put while it was towed. There is no such critter as a risk free at sea rescue.
