You can definitely overpower the H14 type boats as you pointed out -- not much freeboard or buoyancy.
At the Spring Fever two years ago we had an F14 class, with two or three H14s and my Wave.
When the wind picked up, they were a bit faster with their Hooters, but both H14s in the class capsized. No problem with the Wave with Hooter.., and I could have added a lot more sail area.
Haven't had much time to do so, but I had plans for a huge Hooter, fairly large self-tacking jib.
Every time I used it, it was screaming, but broke something every time (bow sprit exploded from the load one time). Still on the drawing board.
