Oh geez, I JUST noticed the daggerboard on that boat. It is definitely not a Solaris. It also looks like a solid foredeck?
I have no clue. An older design for sure. The daggerboard helps, but with the hull shape, beam, short boom etc, it is a bit like lipstick on a pig compared to later designs. Jib sheeting angles are tight with the inboard shrouds, but there must be backstays out of the picture that prevent a large main?
I'm very curious, so if you find any information, please post it.
