My Viszlas used to come out of the water almost like a seal and into my Ducker with little effort on my part. Always wanted to make a ramp, but never did. Now I'm stuck with a 102 lb (when dry!) Wirehaired Griffon. I can get him in, but have to have my stabilizer poles in the mud and pull hard on his collar. I row over deep water, but don't hunt where it is over my chest waders. Duckers are made with air tanks on each end; they have a flat ribbed bottom, so a large person can sit on the gunnel with legs extended inside and they won't flip over. I'll never hunt out of a canoe again.
