I finished the game yesterday and solved all the fates without having to cheese or cheat and was quite pleased with myself especially after uncovering some complex clues that were smartly constructed by the dev. However there was one scene which felt a bit 'guesswork' and that was the scene where 4 people 'disappeared', namely the surgeon, the two English ladies and I think Davey was the last person's name, on the lifeboat.

I correctly identified the people and determined they escaped with the boat missing from the next scene and using the map I worked under the assumption they were alive and in Africa based on the ship's last know location. However it felt like it, albeit right, was perhaps more of an assumed guess and I was wondering if I had missed any other blatant clue or if this was the intended way to solve this part?

Thanks!
