Relief Cuts on Displacement Hull Nose? Help!

Glassed 3 displacement hull boards now & the noses always get away from me when it comes to making relief cuts. These are sharp noses with displacement running about 1.5’ on the hull side blending into a modified v hull (slight). I’ve ended up just cutting 3-4 seperate pieces and basically patching the thing…there has to be a better way. Advice much appreciated folks. First time poster.

Have you considered something like this?
Make a test run/ pattern out of some clean paper before committing to glass and resin?
