I am glassing my first board at the moment. I am making a 6’6" 22 1/2 2 7/8" Retro Twin fish for lake Erie. I need a little bit of help. My glassing schedule is 3 layers of 6oz on the deck 2 layers of six on the base. Oh and it is a stringerless Home Depot EPS. So far I have 1 layer on each side of the board. I was told that for the next two deck layers I can glass them on at the same time. Is this true?? Also I need some help placing my keels. Where would you guys place them it is relativley flat base board. Any info is greatly appreciated. Thanks
