Finally! After months of trying, we managed to get measured today for our ORCI certificate. Everything has to come off the boat first, imagine turning your boat upside down, if it can fall out it comes off. The only thing left when we finished were the lines and the boom, 5 of us took over 2 1/2 hours to get everything onto the dock.
Sails went up on the grass and measured, then we had to test for stability. We rigged a couple of spinnaker poles for supporting a series of weights , and using a water level the heel angle is measured and recorded. The distance to the weights from centreline is recorded also.

We were getting results like 100 kg of weights at approx 3mtrs will give you a heel angle of one or two degrees.

Then the weights are moved one at a time to the opposite beam, each time a dataset is created. What this does is help find the boats centre of gravity, which is then entered into the boats electronic reference file which allows you to virtually rotate the boat through the heel angles, building a GZ curve, which helps calculate your ORCI handicap number.
Good fun, I learned a lot. Then we had to put everything back on the boat again. Not so much fun.10 hours start to finish, tired but a great day.
