I thought I was over this once I got my refrigeration working. I discovered last night that one of my neighbors screwed around with the power at the pedestal and disconnected me! I was all thawed out. At least I know for sure now that it shuts down before it completely drains my batteries. I tie wrapped my outlet cover.
Tie wrap the neighbor! No names needed! :cowbell:

My experience in the outdoors with Scouting and Camping was that we would mix dry ice and wet ice in the cooler. Would buy the dry ice and put it in a brown grocery bag, put the wet ice in the cooler with it and it was generally good for about a week. If you wanted to keep something hard frozen, put it next to the dry ice. The purpose of the brown bag was mainly to keep some insulation between the items you wanted to keep cold but not frozen. The dry ice will keep the wet ice hard frozen longer than it would on its own. My 2 cents.

Earlier in this thread there was a link to a test with three identical ice chests all with the same weight of ice or dry ice put in them. The chests with ice stayed cool longer than the dry ice. It must be that the transfer of energy through the chest is proportional to the difference in temp inside to ambient. Since the dry ice chest was colder, there was a larger temp delta and hence a higher energy loss rate through the insulation.
The greater the difference the faster the heat transfer. As the temperature difference decreases the rate of heat transfer slows.

The article doesn’t have specifics on that incident, but does say - “the incident in Washington bears similarities to a case described in a 2004 report by the US Centers for Disease Control and Prevention in which an Alabama man bought dry ice anticipating a power outage after Hurricane Ivan. He transported a 100-pound block, divided into four brown paper bags, with the windows closed and the air conditioner recirculating the air inside his pickup truck.”

So yeah, don’t put 50 people’s worth of daily respiration in an unventilated car, and let it melt quickly with bad insulation. That’s not quite the same as one cooler with some dry ice in a well ventilated boat. Don’t get me wrong, it’s worth knowing the potential risks and evaluating those, but I don’t think it’s an absolute no-go.

You would be surprised by some people.... there is a ton of articles on a birthday party where they put a bunch into a pool and three people died. Not quit applicable but interesting.

Hi Guys,

Every year (since 2014) I do the Around Long Island Regatta (except this because it's been cancelled). Every year I but one block of dry ice. Half goes in the boat ice box, the other half goes in a large cooler. We also take a few bags of regular ice. We are on the boat from Wednesday morning until Saturday afternoon. By the end of the day Saturday almost all of the dry ice is gone and there is just slushy water in the cooler and at the bottom of the boat ice box.

During the race the companionway is open but the hatches are usually closed.

No one has ever complained about feeling strange b/c of the dry ice. I do admit that fruit stored near the dry ice will absorb some of the CO2 and will taste a little carbonated.

Greg - I buy the dry ice at Countywide Ice Cream in Holtsville. You can buy a full, half, or quarter block. They will cut it for you.
