Inflatable Boat Oarlock Top (Ø35 mm) – Plastic Paddle Lock with Brass Pin

This oarlock top part is the detachable “clamp” component that attaches to your oar and slots into the oarlock base mounted on the boat’s tube. If your original oar holder is broken, worn, or lost, this replacement allows you to restore full rowing functionality without replacing the entire socket assembly.

Compatibility: The top part has a diameter of Ø35 mm – that refers to the outer diameter of the cylindrical section that inserts into the base (the bottom piece) of the oarlock on the boat. This size is common on many inflatable boat models (e.g., Kolibri, Aqua Storm, Bark, EVAL, etc.), but it’s always wise to measure your existing oarlock socket before purchasing. In practice, Ø35 mm indicates it will fit bases with an inner diameter of about 35–36 mm.

Construction: It’s made from tough plastic (typically nylon or reinforced polyamide) in black, which provides strength with a bit of flex. This is important because during vigorous rowing or if the oar gets struck, the holder can absorb some shock without cracking. Running through the center is a brass pin – this serves as the axle on which the top part pivots in the socket, and at the same time acts as the locking mechanism. Brass is used for its excellent resistance to corrosion and wear under friction.

Installation & Use: No special tools are required for installation:

1. Insert the top part (the cylindrical end) into the existing oarlock base socket on your boat’s tube.
2. Ensure the brass pin aligns with the corresponding notch or channel in the base. Typically, it locks the top part in so it cannot pull out vertically. Some designs have a spring clip or latch – if applicable, engage it to secure the top in place.
3. Place your oar/paddle into the U-shaped cradle of the top part. Depending on your oarlock design, there might be an additional clip or strap to lock the oar onto the holder (preventing it from popping out if the boat tips) – if your old holder had one, transfer it over or use the new one if provided.

After installing, test the setup: the oar should be able to pivot up and down freely for comfortable rowing, but it should not lift out of the socket because the brass pin holds it in place.

Advantages of the Brass Pin: Unlike a regular steel axle that can rust and seize up, the brass pin remains smooth and movable. This ensures you can easily swivel the oar up alongside the boat when not rowing (many inflatables allow you to flip the oars parallel to the tube). It also extends the lifespan of the part – brass won’t wear thin or snap easily, even with frequent removal and insertion of the oarlock.

With this spare part, you’ll regain confidence in your rowing setup – no more worrying that a strong stroke might send your oar flying out of the lock. It’s recommended to carry at least one spare oarlock top on longer boating trips, especially if you routinely remove the oars for storage or transport.
