I did not built a DuckHunter but did seriously look at the plans though.It was a toss up between the DuckHunter and a Kara Hummer.I liked the Hummer so thats what I made.Only had a chance to use it once though.It seems to want to sideslip(if that is a word) alot when first starting to get the boat moving,but once moving it's ok.I do think my problem lays in the use of too small of keels.They turned out smaller than I wanted and like a dumbhead I put them on anyway.I may try and make a taller/wider keel that will slip over the small ones and seal them up good with 5200 sealer.Some people say that it doesn't paddle very good,but the first time I used it,I did paddle coming back to the launch.Used a electric motor when I left the launch in the morning.
