Adding Support to Gunnels

[abl1111]

23' Tsunami - I'd like to add additional support throughout the length of my gunnels without creating any 'hotspots' ( while the topside is attached and the boat upright ).

Has anyone done this or have experience with adding structural support?

I'm trying to tighten up this area a bit. I was thinking to either add core ( it's straight up roving/mat ) or, adding more glass 1808 etc in structurally supportive way.

No matter what, working upside down seems like a PITA !

The hull, liner, topside joint is thru-bolted already.
