[Rhodes22-list] Dry Ice

[Bill Effros]

I purchased a dry ice maker at the beginning of this season that could be of interest to anyone thinking of short term cruising.

It cost $125, which I though was a bit pricey for what it is--little more than a fitting for a CO2 tank, and a cloth sack that can be attached to the fitting via a hose clamp.

However, it does work.  And a pound of dry ice in the top section of the ice box will keep the bottom section as cold as a home refrigerator all day and night with just a little effort.

CO2 is not expensive and can be purchased at welding supply companies.  The tank must have a siphon.  That lets out 5 lb. tanks.  25 lb.s is the minimum tank size.  The efficiency is 20-25%.  A 25 lb. tank will fit in the lazarette, however, remember it weighs more than 25 lbs when full, and gets lighter as you use the gas.

If you buy some dry ice before you start, and replenish as you go you could probably stretch it out to a week of cruising if you are careful.  Some of the dry ice would be stored along with food in coolers as Roger has described in the past.

I don't know about the safety factor, however my boat is less than air tight, and I have the pop-top up most of the time I'm on board.
