On the water, conditions change fast. Spray from waves, sudden rain, fog rolling in. Regular binoculars fog up or get water inside, ruining the view when you need it most. Waterproof binoculars seal out moisture and keep working when it matters.
Look for O-ring seals and nitrogen purging that prevent internal fogging. Floating models won't sink if dropped overboard. Built-in compasses help with navigation. Magnification between 7x and 10x balances detail with stability on a moving boat. Larger objective lenses gather more light for dawn and dusk viewing.
