While not using tights the Dundee Club had several 36r yacht hulls made by a friend whose job was making prosthetic limbs. The hulls were made for the clubs centenary in 1985 to put more yachts on the water (club was formed as a yacht club, a number of 6m yachts were converted to radio as well.)
A wooden plug was covered by fabric sleeves and resin, this was then removed from the plug after it hardened. I think it may have been under vacuum in an outer sleeve while it hardened. This gave a strong but light shell and the only difference was the outside showed the fabric weave, this could be filled before painting but most didn't bother. ( Some later hulls were made by vacuum forming in plastic but this soon stopped as the plug was being damaged by the heat during moulding.)
We still have a model of the Bell Rock lighthouse produced in the same way for shows and displays.
