Jamie,

If you do a minimum 6/1 scarf using epoxy it will not matter where you put it.
Mine are a little less and I have them everywhere you have been told to not make them.
Test one out. Make a scarf every 2 feet with over sized stock (7/8" for 3/4" final stringers) and do a test. Bend the stringer about 50% more than your boat needs. For a yost at 24" beam hold the ends and push the center out as much as 18" - stop for a minute at 12" just to convince yourself. you could always bend it till it breaks just to find out how good it is.

Epoxy is good stuff and the stringer should break in the wood, not the joint. Don't use 5-minute epoxy if you can help it.

It is always good to do a test.

I buy western red cedar from Home Depot or Lowes, sorting thru the entire pile to get a couple of good boards. Knots sometimes make me scarf as many as 4 times in a stringer. I hate it but I hate breaking a board worse when I am in the middle of setting up the frame.

Have fun.
