I weigh about the same - and Tom's scantlings are just fine. I've built plenty of his boats, including the Sea Rover, and never noticed any sag or spring in them. Each piece of wood is different, but it should work just great for you. The Sea Rover is a fine boat, which I paddled for about a year - and sometimes almost daily - in a variety of conditions.
Perhaps the pic you saw was one of his aluminum framed boats, which are considerably more flexible and definitely sag. Tom came up with various schemes to stiffen some of those frames.

Too late for you, but I feel Tom's Rolldarka to be superior to the Sea Rover in every respect. A little more leg room, much more stable, carves turns well and rolls even easier. To be fair, I modified my Sea Rover a bit, making it both shorter and narrower, and that was likely a mistake, handling wise. You'll likely be very pleased with yours.

Looking forward to seeing your boat!
