Many boat owners though are finding that as well as producing an interesting and unusual appearance, underwater hull lights also do an admirable job of also providing practical benefits. One of the most popular uses for underwater lighting is fishing, with hull lights acting as excellent bait fish attractors, which in turn attracts a whole host of larger and more desirable game fish species. Using underwater lights for fishing has gotten so popular in fact that a whole slew of companies have sprouted up which specialize in providing a dizzying array of lights geared only towards the sport fishing enthusiast. There is no doubt that using light to attract fish can be effective, and many anglers have used the trick of setting bright lights over the waterssurface to attract fish for decades. Modern versions of this method though, make the process as simple as flipping an onboard switch and illuminating the entire area around the boata far cry from the old days where a gas lantern hung from a pole or rope was standard practice. Placing lights below the waterline can also benefit divers and swimmers as well. Particularly for those who perform night diving excursions, finding the way back to the boat can be made fool proof simply by having someone onboard switch on the hull lights when it s time to finish a dive. For divers who enjoy photographing sea life, hull lights can provide spectacular opportunities to capture images during evening hours that normally would be almost impossible to create. For the diver who finds himself in the unenviable position of having to dive to inspect props or perform repairs, hull lights can prove to be an invaluable tool that allows him to free his hands up for working rather than holding a light and trying to effect repairs at the same time. Another suggested practical benefit of underwater hull lighting includes emergency situations where boaters may be adrift or in some other way in need of assistance. With the water around the vessel well lit, it s hard to argue that finding that craft wouldn t be easier for emergency responders. However, this isn t one of those instances where hull lights should be expected to perform a vital function, and it would be wiser to rely on more accepted methods of allocating assistance. Other practical uses would include illuminating the area around the boat while setting to dock, preparing for cast off, locating the vessel among a group of similar craft at anchor, and other related instances where extra illumination would be considered beneficial.
