On my H37c, the staysail boom is close to the mast when level at the lowest position. I'd like to hoist the sail higher but it interferes with the mast. It has 3 sheaves internally at the aft end. I'm not sure the purpose other than for the outhaul. I'm wondering if it is the original boom. I'm considering cutting it shorter by 3". Thoughts? Also... can't seem to post a photo!
