In the November / December issue of WOODEN BOATS, Harry Bryan has a design for a 10 foot long take-apart sculling oar. His oar has a downward bend at the blade that is in the waterto make sculling easier and to add more thrust per stroke. He has an ingenious method of making his oar two-piece and easily stowable. Have a look. It might be just what you need for an M15 or M17. Connie
