I have a Double Dutch Atlanta 4m boat, cut-down at the stern to around 377cm. At 72kg I find that I am a bit heavy for it and am looking for a bigger boat. Paddled it in div 3 at Fairnilee this weekend and all was watertight.
Let me know if you would like photos sent. I am likely to be at Howsham Weir and Abbey Rapids div 2/3/4 events if you would like to see it or try it out.
