One from the Tornado family, Tornado, Hurricane, etc.

Looks very similar to a Tornado, but different centerboards and no dolphin striker.
Class emblem on the sail looks like the Dart emblem.

"Classic" damage to the hulls. Failed in compression on the inside near the mainbeam.

I dont recogize the emblem. I thought Hurricane, but it's only 16.5 ft and from 1978, earlier than I thought the Huricanes were introduced? Perhaps a mix bag of parts and rigging?

Looks a bit like a Condor. I cannot see if there is a step on the hull at the main-beam. Sail logo is wrong. Same type trailer and mast. Bow is also wrong.

I knew that Grant Piggott would know . His answer: "Thats a Hydra, it was a scaled down tornado from australia". Thanks Grant.

Thanks
Those are fun to solve. Looks like a nice little design.
