Best small wood hydroplane to build w/ son?

My ten year old son and I would like to build a small hydroplane for him over the Christmas break. I have great memories as a kid playing around with some friends hydros. We live on a river and he's excited about building and driving it in the summer. I've surfed around and it appears that all the little (8') hydro plans are from the 60's and maybe 70's. It appears that the Mini Most would be a relatively easy build and perform well. Until he's 16 he can only drive a 10 hp boat. Is this a good boat, and will it run w/ 10 Hp? Is there really nothing newer or better than a 40 year old design? A little runabout semi V seems like it would be more versatile, but I can't seem to find any designs. Does anybody have any experience with this?

thanks, Matt

I can't say how new the designs are. I suspect you will find they have newer construction methods. I didn't investigate though.
