Are you sure the backstay needs to go through it Steve?. The bimini I bought from Whitworths
a few months ago fits virtually up against the backstay and reaches almost to the end of the boom.
So try it in situ before committing to any cutting.
def sam! i dont wanna have to do any mods, but prepared if need be! yeah hg im pretty happy with it. ill see where i get this week fitting it, but first i wanna tighten my back rail/frame which will mean i will need to be a bit of a contortionist to get in the cockpit lockers to reach the nuts!
