If you are using epoxy, continue with it. Mix in some micro balloons until you get desired consistency. It sands easily, and is very strong. You should be able to make yourself a nice fillet.

I use wood dust and epoxy mixed to fill cracks.

You can also mix milled fiber glass.

Dave’s rec is the best for strength, but harder to sand

MASS has powdered wood

If your looking to strengthen that area, and can access the inside of the hull, you can use a piece of triangle stock epoxyed to the floor and transom...

Works good inside the radio box and engine
compartment to help the tub from splitting in half at that critical point...
