Oar lock Insert sleeve for rowboat

thingiverse

Oar lock insert replacement sleeve for rowboat. These are easily lost and often boats don't even have them which makes for sloppy rowing. They slide into the oarlock mount and the oar pins go into them when in use. As you can see from the measurement diagram I made these to fit snug for our boat, but they may work in a standard 5/8" oarlock mount set up to receive 1/2" oar pins.
