Hi Dobrosailor- I may be of some help, as I have 2 sets of sheets for k-boats. I do not know a lot about the sails, and I am only a casual sailor. I am well versed on the k-boat and its history. I have hull #112 in very rough condition, and no mast in servicable condition. I would like to put this boat back into service, but I am not able. Alternately,if you are interested in selling your hull, I may be interested. Please let me know. T.C.
