Polish SAR-1500's
were built by Damen.
Well, it's indeed my fault that when I read that Polish SAR-1500's (with "SAR-" particle as part of class designation) were built
at shipyard belonging to Damen conglomerate and "under Damen license" I assumed it was their design.
(And I'd argue about calling them SAR ships in the sub-type because, for example Polish ones are border guard vessels and as such are used primarily for wholly different tasks)
As for the Arie Visser - true, I didn't investigated it more deeply, but I read somewhere they are related to 1500's, so again made an erroneous assumption.
Unfortunately, this time, number of volunteers willing to participate in the upload is markedly smaller than previously, which results in higher workload, and therefore probability of error, on those that actually do something.
