Stringer material?

Postby fletchster76 » Sun Jan 22, 2017 5:23 pm

Got a new baby on the way so I'm gonna convert my boat over to a more family friendly ride boat. I'm gonna change hulls to a 15' viking with rod boxes. I've had it in the back yard for awhile because it needs stringers. Has 2x4 stringers now. Any opinions on best wood/material to use, would like to keep weight down but want to do it right. I used the search feature but really didn't see anything within the last few years so I figured I'd ask.

As long as the wood is not pressure treated you will be fine. The resin can't absorb into and bond to PT the same.

Regular old spruce pine huh? That will make it cheap. I had heard a recommendation of cedar but I was dreading trying to find that in 2x4x12 and then what it would cost. Thanks for the info.

I will preface this with the fact that I am not an expert. Only done the stringers on one boat. We used 2x4 only for the 2 stringers that the angle iron for the rigging sat on. We used 1x4 for the rest. Saved a little weight. As for the type of wood, I can't remember if it was birch or pine, but it wasn't pressure treated and it was cheap. Ran that boat for 3+ years after doing the stringers and they were still rock solid when I sold it.

The key is getting the glass tight to the stringers with no air gaps and sealing all holes completely when you install the rigging.

Rounding off the top 2 edges of the wood before glassing helps with that.

What way can you check stringers and to what extent is bad considered. Also, does a fiberglass boat have solid fiberglass bottom or is any wood used in between?
