This is one of those "Yes, but" things. Yes, you can go faster than hull
speed with enough power, but there is still a limit. And there's a point at
which your rig simply can't stand up to that much power, and you are
dismasted. Surfing allows a boat to go much faster than hull speed, but it's
also tricky and requires expert helmsmanship.

There are sail boats that will plane off at literally 2 and 3 times
theoretical hull speed, skimming along the top of the water. It's all
a function of weight, length, bottom shape, sail area, etc.
