It's a wonder I didn't find you all back in the summer when I followed this story! Two points I'm not sure were ever made:
1) the amount of calories it takes to constantly stay upright on heavy seas + dehydration from sickness-- I don't think that poor child had a chance to get well had they stayed on the boat.
2) if you read charlotte's blog in February/March, she was having active suicidal thoughts. Now, she did the right things: she wrote about it, she called a few people, she had a medicine change. BUT BUT BUT any suicidal thoughts aren't "normal" and I personally believe it was unreasonable for them to set out with only her as crew three months later. Too much stress.
How can one person be crew and watch a baby and a 3/4 year old? You can't. The whole thing was beyond irresponsible.
I think with the baby sick, Charlotte lost it and I actually wonder if she was the one who pushed the Epirb locator, with or without Eric's knowledge. Once she did (if she did) he would no longer have say in the matter as a rescue would already be in the works.
