Rick, "What you are observing in the videos is characteristic of a slender hull in displacement mode. Water crowds at the bow providing some buoyant lift and there is a wave trough at the stern causing the stern to sink a little. That has nothing to do with dynamic lift generated when planing."
When I watch the video of your pedal boat I see a displacement boat, the bow is high and the stern is down. I dare say that if you added some width to the stern the bow would come down and you would go faster. It would improve your AOA.
Also you are getting a lot of ventilation at your prop, might I suggest an anti cavitation plate. That by itself might decrease the drag in the stern.
I am sorry though, when I watch the videos of the HP's I see the bows down and the sterns up. Which tells me either the sail moment is driving the bows down or there is a Monk affect from the Stern. Probably both.
