    Does VE require csm matt between plywood core and transom skin or is thickened resin sufficient? Between plys of plywood also?

    I would probably use 2 layers only because 1 layer may not fully fill all the gaps between the two sheets of plywood. But if the plywood is very flat 1 might be sufficient.

    20231008_201848.jpg Thanks, I went ahead and used 2 layers of 3/4 Oz csm for 1-1/2 Oz total.
    I got it all installed before evening hit. Pulled up with screws to exterior skin and straightened with a 2x6 from port to starboard.
    Thanks for your help!
