Va Beach v20 project

[Kracker Jack]

I sanded my cap pieces down today and hot coated and glassed the bottom side. I figured if I glassed most of bottom now it would save me a back ache glassing it in the boat. The next plan of attack is to rough in the returns (Carling,Coaming) on the inboard side of cap, I plan on putting coaming pads all the way around the boat so how low should i make my returns? 4"? 3 1/2"? whats the measurement on the factory returns? or in boat building terms the carling. or some call it the coaming.
