For weight in the bow, I’m thinking that when the boat needs to be manoeuvrable in moving water then the pack should sit behind with me jammed back against it; but for better tracking on flat lakes and the like then the pack would be up ahead, sitting on the floor and leaning on the bow; when the gear needs to be certain of keeping dry then it would go in the hold with the seat maybe moved forward a bit; and with a passenger then all the gear (except lunch) would go in the hold and along the tubes as needed for balance. The shape and size should make the boat quite versatile.
The angle between the tubes in the photo is not quite right, partly because too much air is escaping through the stitching and the hot air gun is barely keeping enough pressure in it.
