24m yacht support vessel hull built in Poland - but at which yard?

[rd77]

Hi all,

On 18/7/'13, the short sea vessel ROCKANJE (IMO 9196228) arrived at IJmuiden from Gdansk with the aluminium hull for a 24m yacht support vessel, to be finished Lynx Yachts in the Netherlands:

I have learned in the meantime that the hull was built in Poland, but does anyone know which Polish yard built the hull?

Cheers,
