wide angle? I have tried 10 x 52 but sent them back as they were not sharp

With binoculars as indeed with any optical equipment price does affect the quality, you'd be looking to spend between 100-300 quid. I'm an astronomer not a maritime observer my binoculars are Hilkinson 11x70, 4 degree field of view bak-4 prisms multi coated. 10 years ago they cost me 250 quid. Sharp , so sharp i can cut cheese with them. Top quality so you can use my info as a benchmark.

And if price is a consideration, I can recommend Celestron SkyMaster 15x70 - or Oberwerk 15x70
You should be able to find either for less than £100 (the Celestron maybe a good bit less)
4.4° field of view, bak-4, and optically very nice - but with just the one caveat - not the toughest binocs out there.
But I suppose you get what you pay for
