I've usually doffed fins at the ladder or on the line. I don't believe I've ever climbed the ladder with fins still on. That said, I don't doff until I've got a good grip on the ladder (or line), either.
Since I've never tried it I'm just guessing. It seems like climbing a ladder with fins ON in rough seas would be very difficult. You'd be catching all that wave action! I think it would be easy for you to get your feet pushed off the side of the ladder when the back of the boat was on the downstroke.
Any way you do it, boarding a boat in rough seas can be an interesting experience. Personally, I wouldn't want to be close enough to the diver in front of me that it would be possible for them to accidentally fall off and onto my head. I know it's not much to look at but I want to keep my head mostly the way it is. Tank dents would not be appealing, well maybe some of those guys who are into tattoos/piercings/body modifications may disagree.
