wood stringer options

[Hayden]

I'm having the stringers replaced in my 1986 18' Seacraft. The originals were the foam filled box type. Wear and tear caused the foam to break up inside the boxes and they lost their integrity, deep cracks developed in the hull. The guy doing the work is experienced and suggests 4 wood stringers (2) 2x12 and (2) 2x4. He plans to use untreated pine. I realize treated or other "wet" wood is not good as the glass will not adhere properly. However, a friend in the lumber business suggested a choice grade of treated southern yellow pine, kiln dried. It has a moisture content of 15%, less than untreated SYP which is usually in the 19% range. This is supposed to be flawless stuff and very strong but I'm unsure what is typically used, other than Douglass Fir which seems to be difficult to find. I'd appreciate any feedback from you guys with experience. I just want to make sure we're not making a mistake.

The strength is in the glass you put over the core. I would not use wood. It will rot and absorb water,is needless weight and does not give you any strength. You should reuse the original box stringers,remove the foam and add more glass over them or get a 4 lb density sheet foam and fabricate your new stringers from that.
