So the OPs Boat , varnish in question was painted at the factory?
Then someone decided to strip all the paint and varnish it?
Sounds like it’s got varnish now.
I highly doubt that it was painted stripped and then varnished.
Evidently this one came with varnished teak trim.
Boat builders do all kinds of stuff overtime on their various builds.
I am not an Alwood user but will be one day once I completely stripped all my one part varnish off the boat. I like what I’ve heard about it.
I have read their instructions doesn’t talk about removing all sealent out of the wood that I remember just the old varnish that was applied.
