Which zoom for fishing boat?

[Blade Canyon]

Going gulf-stream fishing all day Saturday with 5 guys on a 32 foot open-console fishing boat. Even though my waterproof Nikon AW-120 gets good shots, I want big RAW files to work with later. I have a waterproof "pickle bag" and will take my cheaper D600 body (FX) and only one lens. That's the rub. My first instinct was a 24-70 2.8, but the other option is the 17-35 2.8. It will be very bright, so shutter speed will be high and VR will not be an issue.

Anyone here have experience shooting on a boat like this? Now I'm leaning to the 17-35mm to get those wide open horizons and the action shots, and use the AW-120 for people pics.

What do you suggest?

i would go with 24-70mm and dramamine. Take some practice shots @ 16-32' i think you will like the shots better than using 17-35mm.
A lot of difference from 35mm to 70mm. Do a pano @ 24mm if you want wide open. Or leave a couple of beers at home and take both.

Hah, I'm not sure how good a pano would be while bouncing around on a boat. Only room for one lens and body in my waterproof bag, and there will be no sheltered place to change lenses at sea. My canned goods (beer) will be carried in a cooler.
