This idea is worth a mention………..Leverages and all that stuff
A clamp was required to secure the tip of the skin
After trying all sorts of nonesense, this Eureka Moment emerged!

It may look crude, but it did the trick!
After applying the waterproof PVA glue to the joint…..
I clamped a lever at the bottom edge of the hull
Attached a cord to the other end of the lever and loosely secured it to a clamp on the bench
A local block of wood was placed exactly where needed and pressure was applied, by pushing the top of the lever
When satisfied with the setup, the cord was finally secured to the anchor point
Problem neatly solved
