Finished work for the time being. Back on Amadeus.
Molded a canopy to get back in the groove.
A layer of 50 gm glass outside 1mm rohacell core 25 gm glass inside no gel coat. 200gm carbon joiner and around the flange, 85gm and nice and stiff.
It's OK but could be neater and could also loose 10-15 gm with out most of the carbon.
