You might find that a soft cooler with a few bottles of frozen drinking water and a pound of dry-ice is adequate for your needs for a weekend. We used a Polar Bear soft cooler for years (and still use it on weekend trips) and find it quite effective, even in the heat of southwest Florida summer temps. A version of this cooler is still available through Bass Pro Shops.

FWIW...

On June 22nd, I was singed up for a Summer Sailstice event, and was ready to take off at 9:00 am from Ventura to Santa Cruz Island for an overnight. I wound up delayed til afternoon because the only other boat from my marina going had his FRIGGING FRIDGE ON THE FRITZ!

Why would his frigging frig fritz delay your departure? Did he have all the beer?
