Thanks fuzz. I know I still have a long way to go but I feel like I am starting to see the light at the end of the tunnel.

I got a few of my bulkheads cutout today. Any opinions/suggestions on whether I need to wrap over the bulkheads like I did the stringers? Or will they be fine to put a layer of 1700 on either side and tab them in with 3 layers of 1700? These are 3/4 coosa as well.

What are you defining as a bulkhead?

A 3/4" thick coosa bulkhead probably only needs a piece of 1200 or 1700 each side and a couple of tapes would be plenty.

If you mean floors below the sole; 1200 and two tapes is plenty..

I was referring to the pieces I have cut out in the above picture that run in between the stringers. I still have more to cut out I just haven’t decided on the exact location for the rest of them.

2 tapes is plenty

Your work is looking really nice. Agree on the 3 layers of 17oz.

None of us are structural engineers so we are making our best guess based on our experience. The range has been 24-51 oz of glass. I am going to say do what feels right to you within the range you have been given. One thing for sure is your work looks very good :wink:

Somehow didn't see Fallguy's rec when I responded. He knows better than me. Agree with Fuzz on making your own call. I'd use the 17 since you have it.

Just make sure to fillet and stagger the tapes and not stack them. I'd go 6",4" or 4",4" staggered.

Main structural components in my build always used 3 tapes; secondary structures used two; non-structural things like cleats used single tapes.

There are no seams in the Skoota untaped. I wish I had used smaller tapes for some stuff. Like 6 oz wovens for the cleats.

I have a forward hatch that is super heavy. Guaranteed to break someone's finger someday. I was gonna glass it cuz it won't dent so easily. It is Aqauplas.

I gotta 2nd Fuzz. The work looks great. I am eager to see it decked. The space across the tank is a bit too wide for walking loads; you may want to glass under that panel if 3/4" coosa. Do some walking tests to see.

Thanks for the compliments. I finally feel like I am getting the hang of things and the work is more relaxing than me wondering if I am doing things right. I am definitely going to have to address the gap across the tank. Right now it is 30 inches across from inside to inside of the stringers. I do plan on gluing cleats on the top of the stringers but that will still leave a wide span. I definitely want to make sure it is strong as the front of the boat will see heavy loads. I still have a few bulkheads to cut out but this is where I am right now.

You can make a coosa i beam. How much height do you have above the tank?
