It isn't just how high you can point - it's VMG (Velocity Made Good) to weather that counts. A Hobie 16 will point really high - and go really slow. If you put the nose down and foot (especially in a breeze), you actually go faster to weather.

A good race committee will set their weather mark to provide about a 10 minute weather leg in moderate to heavy conditions (that's roughly a 40 minute race, two laps around). In 15 kts of breeze, a Hobie 16 can cover a nautical mile straight upwind in that time. That's 6 kts VMG, or about 12 kts over the bottom (actual distance travelled ~2 nm).

Good luck getting a mono-slug to go that fast.
