Q: 5. Would these binoculars be be good for boating in open water? Thanks

A: While the stabilization system in the ZEISS 20x60 Classic S Image Stabilization Binoculars would work well on a boat, the 20x magnification is not considered a good magnification for nautical use. The 7x50 binoculars are considered best for boating and because they are only 7x magnification, a stabilizer is not needed. I would recommend this Steiner 7x50: https://bhpho.to/3otqVti
