I prefer yetti. I bought a 5 foot fiberglass yetti last summer that doubles as a port side seat in the helm area. It holds 200 lbs of ice with minimal melting for 3 days. Engel coolers are phasing out - they stopped making them last year. My buddy has a couple fiberglass engels on his black fin. Good cooler but I think yetti keeps contents cooler for a longer period of time.
