Outback Hull Crack - Repair Suggestions?

I've just discovered a crack in my Outback's hull and would appreciate any advice on what steps I can/should take to seal it and hopefully, keep it from expanding. It is a 2007 hull I received as replacement for a 2006 hull that had leakage issues in the miragedrive well. Photos are below.

The crack is open all the way through the plastic, and approximately 1.25" long. It's hard to tell from the photos, but the location is on the port side, at the rear of the top deck recessed area, where it drains into the rear deck. It's just forward of the rear port rod holder. As far as I can tell, accessing the crack from inside the hull is somewhere between a (censored) and impossible. All suggestions are appreciated. Thanks.

Simple weld repair I think. Above water line.

One guy rebuilt his PA deck with welding to install the rectangular hatch:

Thanks Matt, I appreciate the info. Thanks for the links, although I DID NOT need to read the PA thread. Still in cold sweat from reading that project. Thanks again.

Consider drilling a hole at each end of the crack to keep the crack from getting longer.

Here is a crack I found in my Outback hull yesterday. Looks like it is directly below where the sail mast tube is. Would this KP repair kit thing be the best solution for me?
