S&T Sculling OarScull your small craft with one oar off the transom. Our unique offset curved blade, combined with incredibly flexible native Maine ash, makes sculling a joy. Our standard length is 710, which is suitable for most rowing boats. The shaft has a diameter of approximately 1 1 4". The flex and strength of ash at this diameter makes for an excellent sculling oar. For sculling larger craft, we recommend purchasing a single flatblade oar. One customer
