Andres, Aloha!

Have you put the plastic/delrin chip in the mast base?

You may check out the photos from our regatta this past Sunday on www.gulfsailing.com - note how tight the jib luff remains as the boats round the windward mark and set chutes. The trick to rig tension is to prevent headstay sag when bearing away.

Spreader rake is the key to mast bend and diamond tension, and that path takes you to the sailmaker.
