Suggest you rake the mast only as 'last resort' to correct for 'helm balance' !!!!!!
Also suggest that you contact your mast manufacturer and adjust-in the proper amount of mast 'pre-bend'. Prebend is also usually considered/corrected for in sail design so if your mast isnt at the proper pre-bend configuration ... the sail will 'more full' than the 'design'; more full shape increases (slightly) 'helm balance'.
If you dont know the mfgr. then put in 3/4" forward pre-bend in a single spreader rig and 1/2" for each spreader on a multi-spreader rig.
an example of setting pre-bend from the 'net': A Mast Tuning Guide - The Light Version or do websearch for "prebend + mast". Seldén masts have a very good source of info on prebending - Seldén Mast AB
