Is anyone having issues with their Drop-in outrigger bases twisting where they locate in the Rod holders? Mine appear to have Manta bases made from 1.5mm thick tubing.

 Those are strong . Not what I use though .. I use proper killwell drop in riggers  mine that are about 20 yrs old.. pretty soft rigger a lot didn’t like. They fit into solid stainless rod holders ( decking foam under them) which are real nicely set into alloy stabi gunwales. No issues and have set some 80w tiagras on riggers sometimes.  If drag too tight on a blue will shear bolts out of the alloy if drag is set too tight … but basically ok if set drag 5kg or less.

I find them here now on the Oceanblue website.    https://outriggers.co.nz/collections/outrigger-bases/products/drop-in-bases.

 I have e-emailed Ocean blue. But if these are the only choice out there, I will just have to strengthen them myself. 

you should aslso be running a stay, that stops the forward backward loading at the base and saves distruction

Thought of installing an insert inside existing and then run a stay to bow.

I also had to drill out and replace locator pins as they bent on mine.

the photo of the set from Buckaneer above appear to be the same length notch as the pair I had that failed.
