These boats are another option, a new category of the sport of sailing fast. Apparent wind sailing as it is called.
Also there is the facet of being able to do your 30knts boat speed with 2 people on board in like 12 knts of wind. maybe less.
Many locations have 10-12 knts of wind fairly regularly.
Once the wind is in the 30s then a yacht or a board make much more sense. Although a small cat makes for a real challenge, almost an extreme sport in the 30+ knots wind.
