[quote=Dogboy]I'm not familiar with the Nacra construction, but as a general rule, these anchor points should be rock solid. If you're able to wiggle the tang with your hand, then something has let go. Injecting epoxy isn't going to add any significant structural strength and may just end up masking a bigger problem. Inspection ports are pretty easy to install, I would just try to find out if there are any bulkheads in the area that need to be avoided and then pop in a 4" or 5" port to take a look.
