Oh boy. I guess I'll be pulling the tank. I was going to replace the floor, carpet, strengthen seats, etc next year, but it looks like I may have pushed that project on myself a little quicker than I was anticipating.

I'll pull the tank and put some backing plates on some through bolts. The only good news that I can think of is that all the lag bolts were very solid. The funny part is that I just filled the tank for winter storage and now I've got to drain it. I've also got to get with my basement clearing project so I can make room to bring it inside.

I think for the stress cracks I'm going to open them a little, mix some gelcoat, and see how well I can blend the color. I've got a few other minor places I want to repair and so testing the process on the transom, under the platform, seems like a good place to start. Thanks for all the input.
