Hi Daniel, this is great subject matter for a story. Over-fishing and dredging are really worrying. The setting is also very interesting and there's lots of opportunity to develop a great sense of place and action.
At the moment I don't think you're achieving as much as you could in terms of descriptive writing. As others have said, the story reads more like journalism than fiction. It's easy to slip into this mode if you're simultaneously trying to think of all the things you want to say in a story.
As well as thinking about point of view, you could do a lot more showing of what happens and less telling. Using showing will help you get into a character's POV and make the writing more immediate for the reader. For instance:
¬The boat [does she have a name?] heaved rose and fell through the heavy chop/waves/rollers half as high again the boat. Every bottom of a wave jarred his spine. Icy saltwater stung sharp as pins and would be doing the same to Isaac. There was no point in wiping it away and in any case letting go of the steering wheel would be damned stupid. Skippers had broken their arms and legs when thrown across the cabins of rolling trawlers. Hang on and and keep an eye on Isaac. The boy was scraping the ice-blurred windshield just like he'd been taught. Every scrape with the [what tool is he using?] left a space for more water, more ice and a length of vision that sometimes reached the boat's bow but most of the time was a grey cloud over the wet deck.
I've taken liberties with your story, my writing is a bit cliched and clunky and the seafaring facts are probably wrong, but I hope you can see what I mean about showing rather than telling. You want the reader to feel that icy water, Matt's pulled muscles and his anxiety. Naming the boat will help too.
At times I wanted a clearer description of the seafaring aspects. You make it clear a little later that Matt must steer across the waves rather than end up sideways to them (I think this is how it's supposed to be done?) but that's not obvious in an earlier piece of description. Part of the thrill for the reader will be to learn something they don't know already - how to steer through a storm. I wondered too if Matt would refer to maps or charts. In the UK where I'm from I think it would be charts. This may be just a language difference, but using some technical terms can really help in a scene like this. Too much and the reader gets lost, but the right amount creates atmosphere and interest.
Keep going with this story. I think it's a really good one, it just needs more of the feeling of fictional writing and emotional connection with Matt. He's an appealing character and with his son on board as well, the jeopardy here is high and could be nail biting.
