In November 2014 OKDIA introduced new rules to control the construction of masts and to try and slow down the progression towards more expensive materials and methods being used. This resulted in a Licensing Agreement that all mast manufacturers must now sign.
List of licensed builders.
All new masts built from materials other than wood or aluminum now have to have an official OKDIA Mast Label on them. Further, all existing masts built from materials other than wood or aluminum that have repairs of over one meter in length done to them must also carry a label.
The label proves to the owner, measurer other sailors that the mast was built or repaired by a licensed builder.
The cost per label is £10 including shipping and should be applied by the builder. Orders should be sent to firstname.lastname@example.org
