Not that common a task. There was a used 10' Hopper 2 single seater in Sequim but it got snatched up by someone from B.C. Good luck on the 12' Koffler... I've seen one in the past 6 years on the used market, which I bought... and should've kept, but its all good.
Reviving this thread to see if anyone has any interest in selling there pram...I would consider any other makes/models as well as long as they are not made out of wood(I abuse things too much to have a wooden boat)
