Hoy,
For those of you with a carbon boom, what size are you using? Exterior diameter and interior diameter?
My new sail is longer footed than my old one, so my current aluminum boom is a tad too short. I'm just wondering what size to shoot for in carbon to have a boom solid enough to take the loads. For the record, I'm not sure I'm going to go carbon, depends on the price really, aluminum is cheap

I'm also wondering if a simple carbon tube can take the punishment of an internal cascade for the mainsheet if I choose to go this route as this would add quite a lot of compression that's not present when the sail is directly connected to the mainsheet blocks around the boom...
