Outward angle oarlock pin

Concept: Angle of the oarlock pin, perpendicular to the boat. Tilting the top of the oarlock pin away (outwards) from the boat is indicated by a positive angle, tilting the top towards (inwards) the boat is indicated by a negative angle.
Sizes: Measured in degrees: 0°–3°
+ Outwards, the blade is skipping the water at the catch and digging deep at the finish. As a result, the blade deepens less at the catch and skips less at the finish, which is beneficial.
Inwards, the blade is more like digging deep at the catch and skipping at the finish. As a result, the blade deepens more at the catch and skips more at the finish, which is unfavorable.

Measure: Use the inclino/angle/pitch meter to measure in degrees. Before measuring the angle, fix the boat with the fixing rods or use a batten and glue clamps. It is important that the boat cannot roll and the riggers cannot move up and down. Calibrate the meter by placing the meter on the deck, always in the direction in which there will be measured. So both oarlock pins need a different calibration direction. Set the digital meter to zero. Rotate the spirit level of the analog meter so that it is exactly between the two lines. The meter is now calibrated. Place the gauge against the oarlock pin and measure the angle. Measure the angle on the analog meter – by tilting the measuring plate until the air bubble is again between the lines – and read the number of degrees.

Adjust: Adjusting the outward angle of the oarlock pin can be done in different ways, also depending on the type of rigger. The different options are described here: Adjust the pin pitch & angle
