Details: Keel Support for Jinker/Trailer Repairs

I have left over fibreglass sections from jinker repairs (rust along steel keel support).

They are:
1.5m long;
100 x 100mm equal angle; and
10mm thick (Treadwell) sections.

Internal shape matches bottom of Etchells keel.

Can be seen on Sunshine Jinker (Aus1056) at RPYC Crawley.
