Bridle height does influence change in rake with cant...see image.
Other than that, I agree with your sentiments about macca.
Doing a Macca here, altering the front stay bottom position alone will not cant the rig, the side stays length have to be altered or the mast base position ( easiest and most beneficial in our boats ).
arrrgghhh. my explanation is not enough...looking at the picture it is arranged for two boats, one with a high bridle (as normal for a beach cat) and one with a low bridle (not normal and used for illustrative purposes only).
the rakes are shown for the upright positions of the rigs.
then beside each of those is the canted rigs (with sidestay adjustment) for high and low bridles. notice that the high bridle
decreases rake with cant and the low bridle
increases rake with cant.
the only way to cant the rig without also changing the rake is for the forestay attachment to be at the same height as the mast step. this is with a fixed length forestay which our class rules require with the rig tension adjustment requirements.
mmm...pretty girls on pretty boats...it is my happy place
