I have had to turn back on the odd occasion, but I don't enjoy turning back. There have probably been more than one occasion where I didn't turn back and should have, but successfully made it through. What seems like such a big reason to press on at the time, in reality, can always wait until later or the next day. Processing those reasons at a time of duress puts us under even more stress.
I've also had many a boating experience where many would set off and not make it and had to turn back. Sometimes you might be stuck for days whilst waiting for some better weather, so you just have to deal with it, seek alternatives and ride it out. A day off work at short notice is better than never showing up again.
PS: Not suggesting that this has anything to do with this tragic accident, am just adding to the pressing-on posts.
