I import a fine range of wooden oars and paddles from an old establshed manufacturer in Poland. They use best Baltic pine which is light and strong. They can produce every kind of oar and paddle you can think of but I limit my current stock to flat bladed rowing oars between 1.95mts and 2.7mts in length, which are the most popular. I can supply them with rubber collars for an small extra charge.
You will find my prices much cheaper than most chandlers and I deliver around my locality of Poole for free. Dorset and Hampshire for £20. Delivery is also available elsewhere in the UK by discussion.
