I have had a similar boat. Every time we went out in a decent breeze we broke something. Everything from beams ripped out of the hull to delamination, deck and hull coming apart, ripped out forestay fittings, broken rudders and centerboards.. Fixing up an old Tornado is doable, but taking it apart and checking the inside is a good move in my opinion. Old Tornados are great movers, but they did have a reputation for beeing fragile back then.

There will be a lot of work to make that boat nice again. The question is always if you want to work on the boat or sail..
