That is a concern, namely, the arrangement in option B would place large compression loads on the CF pole, something CF isn't particularly spectacular at handling.

or is it torsion CF struggles with? i always get those mixed up.

In any event i could always run an aluminum tube from the front beam to the forestay, hook all my wires to that, and slide the CF tube inside.....

i'm just really not crazy about fabricating a 112 inch long bow foil. haha
