Mike – Ours are 2.4m or about 8ft, plastimo oars. They fit reasonably well in our Mk2 and with a small modification are comfortable to row with. The mod consists of moving the collars about 150mm further out (guessing) to bring your hands closer together when rowing.
Everyone says they need to be longer if possible but we manage fine and any more length would make stowing more difficult.
See you at Beadnell Bay.
