its kind of late on this one but i been busy killin springers I bought a 17x56 diamond back new 2 yrs ago it has been the best rowing boat i have ever owned i have had alumawelds and willies in the past and the diamond back is a dream to row compared to those doug at diamond back was willing to set it up any way i chose and with out any extra cost for my modifacations to his design in my opinion the diamond is one hell of a boat and a lot less cash then a koffler willie or alumaweld
