Opticron's Marine-3 7x50 Binoculars feature enlarged porro prisms and anti-reflective multi-coatings, which maximizes field of view, cross-field resolution, as well as low light performance. They are nitrogen gas filled, waterproof, and protected from knocks and bumps with specially mounted prism assemblies and a strong die-cast aluminum body with thick rubber armoring. They are very durable, but also quite large. You probably don't want to lug these around all day on a hike, but they're superb when size and weight aren't an issue such as at your helm. Marine-3's have individual eyepiece focusing which means they have a large depth of focus. Once your eyepieces are set to your eyes the need to focus is generally eliminated for everything over ~50yds, so you can just pick them up and go.
The Marine-3 was selected as Yachting Monthly's Best budget buy binocular. It is a great option for captains or anyone else requiring a durable binocular with an emphasis on long distance viewing. Supplied in a soft case with a rainguard, objective lens caps, and a comfortable wide neck strap.
