Pleased to hear the rig has arrived after its mini tour, look forward to seeing you out on the race course again
With regards mast rake, 5m is a good starting point, measured from the black band to back of transom. The trick is measure the distance between the black band at the top and the one at boom level when the mast is on the the ground, this means you can ensure the tape measure is always in the same place when hoisted.
