Frequently Asked Questions
Do I need a rotomolded cooler for a small boat?
Not always. Rotomolded coolers provide the best ice retention and durability for longer trips, but they are heavy and take up space. For day trips or small watercraft, a high-quality soft waterproof cooler can be lighter, floatable, and easier to stow.
How should I secure a cooler on a small boat?
Use built-in tie-down points or wrap a marine-rated strap through molded handles and around a deck cleat. Add non-slip pads under the cooler and route straps so the box cannot slide forward or sideways. Securing the cooler prevents accidents and protects the contents.
Can soft coolers keep ice as long as hard coolers?
Soft coolers with thick closed-cell foam can keep ice for a full day and are great for short trips. Hard rotomolded coolers with thicker insulation typically hold ice longer—several days to multiple days—especially with block ice or frozen packs and proper pre-chilling.
