Re: Sailable projects?
Coolers vary a lot boat to boat too. On my Catalina 25 the cooler would keep ice solid for a day or maybe two (reports from similar boats are that only 2 sides are insulated), on my Pearson it'll keep the same ice solid for 5 or more days. This is in days with 80 degree highs, 60s in the evening.
Most of the 12v fridges when installed into a good smaller cooler seem like they need about 25ah of power per day. That means a pair of group 24 batteries last roughly 3 days, or somewhere around 100-150 watts of solar panels can keep up with the daily draw.
Whenever I price it out I decide that ice isn't much of a hassle and a lot less expensive.
