Ideally, the binoculars should be rugged, durable and water-resistant to be used in different weather conditions. Generally, binoculars with 7 - 8x magnification range are suitable for general use and travel, as anything greater will result in unstable images. Objective lenses of 25 - 35mm range will keep them compact while maintaining sufficient level of light-gathering capacity in the day time. If using binoculars in dawn or dusk, you would want objective lenses with 40-50mm range, but keep in mind that the larger the objective lenses, the bulkier the binoculars will be.

As you would be in close proximity to waters, it is advisable to get a pair of binoculars that is waterproof, tightly sealed with nitrogen. Pick a pair with high light gathering capacity or large objective lens. Objective lens over the size of 40mm is sufficient enough to yield bright images. Choose binoculars with lower magnification for marine/boating purposes as they would result in less image shakiness as opposed to those with high magnifications. This is especially true when you are in a moving boat with continuous wave motions. Experts believe that a good marine binoculars have a balanced 7x50 specifications range. As water conditions may be rough, it is also recommended to get an Image Stabilization binoculars to counter the shakiness.
