Board Design-Foil

I am building a board for a beginner surfer and was wondering where to put the foil of the board. I"m dealing with Rhode Island East Coast waves, so I may put the foil slighly forward rather than behind the center mark of the board. Does this sound correct to anyone? Even with RI’s small waves, should I put the foil behind the center of the board for a week paddler? Thanks for the help! Rob
