Reinforcing with carbon

[meatball]

So, just as a second opinion, for a mostly flatwater boat, and bay chop (no higher then 5 foot chop, and closetogether, so you cant launch over 5 feet or so, at least not with my stocker)

I could go with one layer of 17 oz biax on the sides (extra strip along the bond line), and lip,

3 layers under the pole mount,

one layer of 9 ounce on the bottom,

and one layer of 17 oz in the nose (does the nose need reinforcing? With the foam I'd think it wouldnt, just curious)

How do I go about reinforcing the rear? Can I get by by just hardening a layer of 17 oz and cutting it and riveting/epoxying it to the crack prone area in the rear from incomplete BR's? Do I need to reinforce the transom or the bottom in any way?

My tray has delaminated from the foam, and has formed an air bubble (the glue in the engine bay came apart a bit allowing air in) so I may refoam if I find it wet, But I definitely need to cut open the tray and relay the glass there, so Ill put an additional 17 oz layer on when installing the footholds.

Does this sound like enough or not enough for a 90 percent flatwater/bay chop/cruiser wake boat, and occasional surf (2 hour drive)?

One last question, the exhaust side tray wall on my SJ has beercanned inwards. I'm guessing from the exhaust tube heating up the foam. Is this a common thing? And what exactly from?

Just planning for this winter!! :biggthumpup:
Need to start getting parts together.


Thanks for any comments

carbon and carbon kevlar are for the bling AFTER you reinforce with biaxial mat.

the difference in weight is minimal. stop eating cheeseburgers and large fries if youre thinking that a little extra resin is killing your game.

Yep thats how mines done 12oz biax and 5oz plainweave carbon. But on the next one I will just use Carbon kevlar and no glass. I would like to see some bare hull weight comparisons on a biax reinforcement and a carbon one. I bet the difference is pretty minimal.

I'm sure the difference is minimal. I think I only added 18lbs on the last one I weighed and I used a LOT of glass.

meatball, that sounds like plenty. If you'll have the footwell areas open, reinforcing from the inside will look and help better than a biax deflector on the outside...
