I drew these oars up to suit the Goat Island Skiff, for a particular person. They are suitable for most boats with beam of 4'6" (1.37m) to 5' (1.52m) - email me if you are in doubt.
As they were for a particular person I haven't created an integrated plan pack for them. However, the FREE PADDLE PLANS use exactly the same methods and sequence of assembly - so use the drawing for the oars and the paddle method and all will be well.
IMPORTANT - One thing to remember though is that the SPAR GAUGE that suits the oars will be larger than the one for the paddles. There is information for making any size spar gauge in the paddle plans - choose the right one!
IMPORTANT 2 - It is recommended that the Oars be epoxy sealed and varnished - they will look great - but the handle should be left natural for good grip. It could be oiled to protect it from the environment
