G'day from Australia / Kauri sea worm

[Crayboat]

Hi I am new to these forums.

I am currently restoring a 36' NZ Kauri timber crayboat and was interested to know if anyone knows why NZ Kauri is so good at resisting marine worm infestation.

Cheers.

I have removed a few metres of worm eaten kauri from a yacht I'm restoring.
Teredo in three planks, and gribble in sections down aft where not much light reaches. The teredo was in planks that had rested on mud when the tide was out, and the gribble where there was damage.
I was suprised with how little worm there was as the vessel had been pretty much abandoned for years.

Another NZ timber that is known for resisting worm is Totara, the Soren Larsen was sheathed in it a few years back.

Hi Troy,

Thanks for your response... very interesting.

My vessel was built in 1968 out of 1.5" thick NZ Kauri planking. The complet hull has been taken back to bare timber.
During it's life it had periods of not being slipped for up to 3 years and yet the planking is unmarked like the day it was built.

Best of luck with your vessel and may all your winds be fair.
