stringer advice

[prolinews]

Well I'm getting started on another project a 20ft legend bass boat. So far I've pulled the motor pulled and all hatches, drilled out all rivets the cap is loose and ready to be pulled as soon as I build a rack. I'm getting my material list I"m going to use epoxy resin and coosa composite instead of wood. The stringers are 13ft long the longest panel I can get is 12ft . The strigers are 3/4 I'm going to have to make a joint some where. I'm thinking of a butt joint with butt panel under seat frames about a 9ft+ 4ft section. Any suggestions? also I'm ordering 9 gallons of resin is this enough? doing floor stringer and transom. I've been told the coosa sucks up resin.

Re: stringer advice

I would not splice the stringers like you stated, using gussett plates both at the same exact spot will still give you a spot for failure. Personally I would either use 2 layers of 3/8 and stager the joints, or even 1/2" and increase the stringers to 1" on them.

I have used 12 gal of epoxy for my 21' cuddy cabin but that also includes reglassing the entire interior hull of the boat, complete new deck, glassing the bait wells etc.

Coosa isn't to bad for sucking up resin, I used it for my transom but to be honest although its really nice stuff, it is a little pricey. To do it again, I would go with ACX and save the money for other things. I know they say it is impervious to water and such but so is ply once you seal it & glass it in, especially if your using epoxy.

Hope I have helped a little, Good luck with your project

Success I finally got a picture up! Now I have to download the rest. The biggest reason for going with the coosa is for weight reduction. The boat is lite to begin with, but if I can shave a few pounds might get another 2 or 3mph. I am a speed junkie. I agree about the double 1/2 for the stringer stagger joint stonger and more reliable. I think when I order resin I'm only going to start with 6 gallons . I have a two week vacation coming up and just trying to get enough materials so that when I start I don't have to stop.

My boat originally came with a 3/4" plywood stringer and I'm using (2) 1/2" ply glued together to make mine.

I used 4 1/2 gallons on the same boat. I used red oak for the stringers, cut and shaped to match old ones, and 3/4" plywood for deck. Treated wood as follows;
Mix fiberglass resin and dilute to watery consistancy with acetone. Paint 3 coats on all surfaces. Acetone evaporates and impregnates wood with fiberglass resin. Add final full strength coat of resin and add fiberglass mat, then 1 final coat of resin. After cure, rough up resin with orbital sander before applying carpet adhesive. Use a roller when applying carpet to eliminate bubbles and get carpet smooth. I used a heavy wooden bakers rolling pin.
