how much ice is needed for ice fishing插图

How much ice do you need for a dinner party?

That’s about 11.25 pounds of ice. With one ten-pound bag of ice, you’ll be pretty close to the amount of ice you’ll need for a dinner party with 12 guests. Assuming your ice isn’t melting in storage, this is a good equation for estimating how much ice you need for a party:

How many ice cubes are in a pound of ice?

Multiplied by three cubes each, that’s 180 ice cubes! An average ice cube is about one ounce, which translates into about 16 cubes per pound of ice. That’s about 11.25 pounds of ice.

How many ice cubes do I need for my event?

Assume your guests each enjoy one drink per hour, with an average of three ice cubes per drink (some will surely use more, but others might not use any). Twelve guests multiplied by five hours is 60 drinks. Multiplied by three cubes each, that’s 180 ice cubes!

How long does it take for ice to melt in water?

A single ice cube will melt in about 90 minutes in a 75F room, 60 seconds in hot water, and about 15 minutes in cold water. With an ice pack or bag of ice included, an insulated lunch box will stay cold for about 2 to 2.5 hours. A 3lb (1.5kg) bag of ice left in a 73-75F room, without insulation, will melt in about 5-7 hours.

The Importance of Correct Estimation

Accurately estimating the amount of ice needed for a fishing trip is crucial and walking the line between having too much and having too little may be difficult. Space is at a premium on most fishing vessels. If the fishermen bring too much ice they may not have enough space for fish and other cargo and they will incur needless extra expenses.

Basic Formula and Rule of Thumb

The following chart shows the amount of ice needed to lower 10kg (22.04lbs) of fish to 0°C (32°F) for various starting temperatures of the fish.

Consider the Size of the Fish

Another important consideration to determine the amount of ice that will be needed for a fishing trip is the size of the fish that will be caught. Naturally as shown above the more fish caught the more ice will be needed to safely cool them. However, besides the pure weight of fish itself, the size of the individual fish is also a factor.

Consider the Length of the Trip

A fishing trip that lasts a day or two is quite a bit different than one that lasts more than a week. Naturally the longer the vessel is out to sea the more ice is needed on hand to compensate for melting. Likewise longer duration trips may yield more fish which would require more overall ice to cool.

Consider the Storage Conditions

Finally, the storage conditions on the boat are also a crucial factor for calculating the amount of ice needed. If the storage hold is well insulated and double lined it will hold in cool temperatures and keep out warm temperatures vastly more effectively than a non-insulated hull and will thus not require as much ice to get the job the done.
