Here's the thing, is she truly going "alone" or is there going to be a flotilla escourt or a one boat escourt, or what?
If there is going to be any escourt, what's the friggn' point? All she would be doing is taking directions from the escourts anyway. Are they just trying to get into the Guinness book of stupid ideas?
Now, if instead she is truly going -alone- as in zero escourt or outside help, well, that's just stupid. Forget about the weather, how is she going to deal with pirates for example? What is she Annie Oakley? And can she physically pull herself back aboard if washed, or just trips and falls overboard? Even if she is wearing a harness and teather it's a tough haul if the boat is moving.
And when (not if) she turns up missing, who will be held accountable?
And Robi, you can appreciate this, in that story about the shortest boat I mentioned above, the reason Hugo had to leave from Nova Scotia on his second crossing was, the US Coast Guard sent him a letter which said his vessel was unseaworthy and if he was found in US Waters, he would be towed in, arrested, and his boat would be confiscated. So he went up north to launch.
