It's time to set the record straight
If your logic were true, then football, both Aussi rules and American, rugby, hockey, any kind of alpine skiing (with maybe the exception of slalom), freestyle/mogul skiing, auto/motorcycle/boat racing, bobsled, skeleton, luge, pole vault, ski jumping, high dive, etc. the list could go on and on, would not currently be sports. Either too dangerous or not accessable enough to the masses. But somehow these are all sports and enjoy varrying degrees of popularity across the globe.
Snowboards do go fast. The 1999 world speed record for snowboarding is equivalent to 125 mph.
: I've only gone that fast in a car and on a motorcycle. How 'bout you? I don't know what the current snowboard stats are if they are different, but the current ski speed record is only 29 mph higher at 154 mph (and the snowboard record is from 7 years ago).
I don't know if you've ridden a race snowboard, but you can tuck and get lower in the tuck than if on skis, therefore becoming more aerodynamic. As far as the lowered edge control, the same issue occurs for skiers. Skiers also don't stay in a tuck the whole race, they are forced out of it to mangage the turns (edge) and bumps and rutty terrain, so as far as a challenge for edging, it's no more of a challenge than what skiers go through. And that challenge is the idea of the sport: see who can make it down the course in the fastest time possible, managing the turns, slope, rutty terrain and equipment to the best of one's ability.
So my question to you is are your comments directly from experience, or just speculation?
A snowboard downhill racer would not choose a snowboard that has a sidecut that's "grabby". This wouldn't make sense. The board would be squirrelly at speed and not great for competition. Just like skis, snowboards are designed for their desired use. So a downhill snowboard would not have the sidecut that a slalom board would, just like skis. I just checked the specs of a race ski and race board from the same company and the ski is at 13.5m @170 and the board 12m @173. Crazy that they're almost identical. So I guess that the skis are just as prone to "hooking up" as the boards
. Glad I only have to deal with one piece of dangerous equipment.
