Michael,
I'm definitely intending to follow Matt's advice.
I've now got all 6 hull planks assembled, awaiting sanding on the joints, sanding around the edges and then epoxy coating, before I start the hull assembly in earnest.
I think it's just a base epoxy coat that goes on at this stage, to seal the wood. For strength the glass cloth has to overlap the seams of the assembled hull, so goes on later. I guess one could put the glass cloth on the panels before they are bent to shape and then put glass tape on the seams. But that could make the panels too stiff to bend, so I'd rather not risk it.
The only place where I think it is recommended to use glass cloth before assembly is the inside of the centreboard case,
Regards,
Anthony
