Maybe it's just the angle of the picture, but could there be a little twist in the hull? It looks like the plywood seam farthest aft slopes slightly from right to left and the one farthest forward slopes slightly from left to right.
It might not be a bad idea to lay a level and straight edge across the gunwales aft and forward to see if they're both level. If there's a twist, it will be a lot easier to correct before the deck is glassed in and it becomes permanent. Or maybe it's just my overactive imagination.
Anyway, your work is moving right along. You'll have her in the water in no time at this rate. I see you've made good use of the space heaters to keep your resin active. I think I'm going to have to invest in a couple more of those myself.
