That is a beautiful thing if you are blessed with a boat freezer that will reasonably freeze warm water? Not all boats are create equal. One issue with this practice is the risk that the basic rule that "only the Admiral who has taken the leadership tasks in the galley ever opens or goes in the boat freezer" could be breached.

Ice Management is a learned talent on a boat. First and foremost never add hot beer or drinks to any cooler except when the cooler is being packed with new hard ice. Place the coolest cans of drinks in the cooler and pack that cooler with clean, hard ice and no water. Drain that cooler as the ice melts. Add no new drinks until the next ice run is complete. When possible appoint a skilled ice man as the dinghy captain and cooler manager. Dinghy Captain should enjoy exploring to get ice and have the sole task during any engine operation to keep the dinghy painter clear and the dinghy clear of any exhaust of water discharge. When the dinghy moves the dinghy captain runs the clean and dry dinghy once his guests have boarded. Some young people can make great Dinghy Captains. Some adults should never be trusted with the duty and freedom that comes with "owning" the dinghy and ice for the group. The Dinghy Captains duties start at checkout to make sure they know everything about the dinghy and your boats dinghy starts reliably.

Last always stay out of Mom's boat refrigerator and freezer. Unless you are fully prepared to run the galley stay out of the galley. That rule triple applies to rhum drinkers playing with blenders.
