So I'm making a lot of progress on prepping my 15' whaler exterior hull. Had the bottom farrow blasted and now doing final cleanup before repairs start.

What I did notice was on the port side, there was a rather large area that had cracks:

Questions is whether I should worry about this and grind out all the gelcoat and go through a full repair or if this is okay to leave as is.
