Hermit- the sides including the 1/4" corecell are a little over 3/8 inch thick. The top is 1/2 inch thick including the 3/8" corecell. I can stand on the top without any flex and I weigh about 190. The seat box weighs 41 pounds.
Biglew- The seat box pictured will be used to store dead fish. The other one I'm making will have a small livewell in it. Both will have liners glassed to the underside of the seat box with appropriate plumbing and both will be foam insulated. Below is a picture of the harbor freight tool I use to cut glass.
Ken- I get by with about 5 hours sleep... believe it or not I have been working 10 hour days lately. Most of the work is done at night and weekends. I usually don't leave the shop till around 10-11 O'clock...and I have help with the sanding that needs to be done...I have not been out fishing since November...most importantly my family is very understanding about my boat addiction. I just want to get this thing finished so I work fast

BTW you are moving along nicely on the 27.
Titaniumboy- both hatches are cored with plywood cut into squares. If you go back and re read the project from 2 years ago you will get the answer as to why we core with squares instead of one big piece of wood.
thanks fellas for all the cheering
