Hole at bow anchor plates

I have an old wooden mirror (40250) which sits on a mooring on tidal mudflats in the summer - when it isn't being repaired! Unfortunately today in a gale it flipped over, pulled out the pointy thick bit of wood with anchor plate where the painter attaches, and also the anchor plate for the forestay and left a hole in the ply at the bow where both anchor plates and the pointy bit of wood had been attached. In spite of having turned turtle on the mud with all spars flattened underneath it, that seems to be the only damage (other than existing repairs that need doing - there is no end to them!). I'm thinking about getting two pieces of wood and sandwiching them either side of the original ply at the bow. It's not in a position where it needs to be watertight, but it does need to be strong as it can get a buffeting on the mooring - it came adrift on a previous occasion when the anchor plate for the painter came off as the screws just pulled out and all I was left with at the end of the painter was the anchor plate (luckily the boat washed ashore rather than out to sea). My question is, what type of wood would be best? I want the sandwich to be thick enough to screw the anchor plates into with decent screws. My previous repair with better screws held firm today, but the next weakest point gave way - this time I had anchor plate and pointy bit of wood at the end of the painter (the tide was out so the boat wasn't going anywhere and I now have it attached at a second point too, for good measure!). It seems the pointy bit of wood (wish I knew what it's called!) is only held on by glue and a few nails, so I want something more substantial to use as a mooring point.

I'd welcome any suggestions as to type of wood and thickness and whether a sandwich is the right way to go. It doesn't have to be pretty, nor does it have to conform to class rules (I only potter about in it). I'm not great at repair jobs, they're usually a bit of a bodge, so the simpler the task the better. I have no indoor working space so have to do all repairs outdoors and I have limited tools.

Also, any suggestions for a cover (mast and boom up)? The cover also got badly torn (it had lots of holes and was due for replacement anyway). All the covers I've seen advertised have straps going under the boat, whereas my existing cover has eyelets all round with a rope going through so you just pull the rope tight and tie at the bow. Straps going underneath are not ideal when the boat will be sitting on mud!
