Hello Alan
I'm sorry, I misunderstood that at first
so I put small drops of glue ( 1mm ) on the underside of the base plate / waterline about 1 to 2 cm apart along the outer edge and a few in the middle if the hull is a bit wider .
To remove I use a full blade of a cutter demolition knife. This is quite simple .
I hope to have helped you with this
Best regards from Styria
