Too late! There are already a lot of holes there!

This seems adequate, I think.
Certainly the bolted winch stand itself is fine. And I frankly doubt that more screws into the horizontal pad would help; if it's going to break or come loose, I feel it will do so with or without extra screws. Actually, more screws might even weaken the cleat board.
More likely, if it breaks it will be nearer the cleat, and not where it attaches to the coaming anyway.
But this is a pre-existing setup, and it seemed to work just fine during its previous incarnation. Where were all those extra screws before?
