I don't know about "normal". Slocum wasn't, Chichester wasn't. By definition, to do a sort of endurance style of sailing, you have to be a little crazy. If it's accompanied by competence, people forgive weird, or at least tolerate it (not that individuals should pay attention to herd mentality, necessarily).
But the decisions this guy has made...and from his own writings...do not reflect more than dubious decision-making, a touch of mania, and a monstrous self-absorption that nonetheless is able to persuade others to participate in both his achievements and his delusions.
The whole "spaceship boat" theme was dubious as an analogy from the first, and seemingly indifferently planned. Bringing aboard an inexperienced girlfriend with apparently compromised inner ear organs...and then to knock her up
...seems to be more about semen than seamanlike.
This is saltwater reality TV, a barren stunt and a great big begging bowl presented to the credulous. It doesn't advance anything beyond a bank account.
Finally, I even concur about the Hunter
. Even a ferro-cement Hunter
