Advice please: Best everyday compact / lightweight binoculars for general use

I work in the Caribbean and spend a lot of time in outside, on the water, and generally in areas where I'd like to check out boats, nature, and the very occasional bird. I wear prescription sunglasses and 90% of my use would be with those script sunglasses on. These would live in my pack that goes everywhere with me. I recently got the Leica 8x25mm Monovid but I can't get comfortable with just one tube. This is a buy once cry once situation so Leica or Curios are on the table but I don't have the access (or time) to shop and test. Must haves: Durable, small, lightweight, works with my prescription Ray-bans, and saltwater-environment capable. Thanks in advance!
