What is the best marine flashlight out there? As you might expect, the answer is subjective. However, there are several things we can agree on:

The best marine flashlight would:

  • need to be waterproof
  • have a grip that is non-slip
  • not be too heavy
  • have an easy to operate switch
  • be very bright
  • have long lasting power and potentially be rechargeable
  • (Extra feature for spotlights – a collapsable stand for hands-free operations)


Oh, and don’t forget that a marine flashlight needs to serve boaters both day and night! How many times have you had to inspect dark engine compartments, bilges, and under-deck areas in broad daylight?

Sailors – make sure it’s bright enough to shine to the top of your mast at night!


So what flashlights make the cut?
