Are you planning to sail that tri on one hull?
I think you will find that one Blade hull dont have enough bouyancy to give you the performance a cat would do.
There is in my opinion a crossover point on cats vs tris where the extra hardware of the tri slows down the boat until a certain size is reached. Below this size the cat is the better performer. Especially a potent cat like a Blade.
If you want to experiment, why not work on a tilting rig instead.
