Weight vs comfort: car camping or backpacking

On a boat, weight matters less than footprint and stability. A cooler that fits under a seat or doubles as one saves space. For kayaks, a small soft cooler is often best; see our best small cooler guide.

Weather & season ratings

Coolers have no season ratings. Sun is the enemy on open water, so UV-protected shells and light colors help. Keep the cooler shaded when you can, and pre-chill it before loading.

Setup, packing & storage

Pack ice on the bottom, drinks next and food on top in a dry basket. Secure the cooler with a strap or tie-down so it does not slide. After a trip, drain, rinse and dry it, then store it with the lid open.

Materials, repairs & warranty

Stainless hardware resists salt. Rotomolded LLDPE shells are the toughest. Replace worn gaskets and latches when needed. Warranties range from one year to lifetime.

How much should you spend?

• Under $70: compact marine coolers like the Igloo Marine Ultra; the best cooler for boats under 70.
• Under $100: larger marine coolers and basic wheeled models; the best cooler for boats under 100.
• Under $200: big marine coolers like the Coleman with UV protection and stainless hardware; the best cooler for boats under 200.
• Under $300: rotomolded coolers like the RTIC 45.

How long does a cooler last?
