aluminum pole thickness vs CF

[asdf777]

I already placed an order - flying next week and need to get everything ready by Monday, but hopefully it will work out: the pole is 2 3/8" OD, 0.90" Wall thickness, 94" long. CF filament wound, from forte carbon. I'm replacing the radome with furuno 15" scanner, so the total pole weight with the pole itself, scanner, mounting plate, cables, and antenna mounts should be less than 20 lbs.

20 lbs (~10kg) at the top max, so assuming the boat heels sharply (free fall acceleration), the force on the radome would be:

F = ~10 kg * ~10 m/s^2 = 100 N

So the max moment should be with 2m above deck: 100N * ~2m = 200 Nm.

Does that sound right? What do I do next - how do I apply this value to CF pole?

Thank you,
Gleb

Hi again,
Moments, we need moments of inertia for a meaningful comparison. Having said that, for this application -- I thought somehow that you were making a spinnaker pole -- what you are getting should amount to massive redundancy.
Fair leads,
