This is a less expensive option than modifying the boat. The way I transport 100+lbs of ice for fishing trips is in these soft sided coolers. You can transport the ice in these bags and add ice as needed to the front box (or store your drinks in them). They are easy to load/unload and the empty bags store inside my console. If your buddy needs ice you can just drop a bag overboard and they can pick it up. I didn't get this exact brand of cooler, but they look identical and can hold approx 15 - 20lbs of ice each. I carry 6 of them. There was a JOB LOT special $15 each.
