Is more tabbing needed

[outasite]

When fitting my new stringers I got the fit to within an eighth inch,then sanded (60 grit)primed the floor and stringer with wet epoxy.Then beded into a layer of thick Cabosil and faired it out.After it set,the whole stringer was covered with a layer of 8 1/2 Oz 45/45 than extends about 2 1/2" out onto the floor. Question,do I really need more tabbing for the stringer to the floor? I like the look as is.The out side of the stringer is set in mud 1" deep as it rest against an inside strake.it sure seems tough as is.
