To transition skis, you buckle your boots, lock your heels, and can remove your skins without taking your skis off. Most experienced ski tourers can transition in 1-3 minutes without too much fuss. Adding layers and fussing with helmet/goggles may take an extra minute or two. In comparison, with a split board, you have to unstrap both boots, remove both skins, remove both bindings, assemble the board, reattach the bindings (often with a little de-icing, depending on the snow conditions) then strap on the board. Then you do the opposite at the bottom. I end up waiting around 5 minutes at each transition for splitboarder buddies, even ones who transition fairly quickly. If you make 5 laps in a day, that’s around 50 minutes of standing around. (5 bottom transitions and 5 top transitions, 5 min wait time per transition). Obviously if youre only transitioning once, and plan on hanging out in a summit for a bit, the transitioning efficiency become less of an issue.
Second, In terms of skinning, the efficiency has to do with weight and flats. With modern ski touring equipment, the boot attaches to the binding at the toe, so you’re not lifting an entire binding during each step. In contrast, unless you go hard boot, you’re lifting an entire binding on each step. I don’t know apples to apples weight comparisons between ski and splitboarder weights, but assuming equal total weights, lifting an extra couple of ounces each step over the course of a day will equal a significant difference in energy output.
The final thing as danmelon alludes to is traversing in split mode. On skis, you can negotiate weird downhill/off camber traverses fairly naturally. On a split, unless you develop experience, that 20 foot downhill off camber traverse around an outcropping on an exposed ridge line becomes a bit of a chore.
Finally, there’s the issue of flat run outs. Skiers can skate, pole, or sidestep to get through flats in the backcountry. If a splitboarder loses momentum, they either have to boot, or transition. When the snow is deep, booting is not an option. So a transition is required. Another case where what is a simple task for a skier can take an extra 10-20min for a splitboarder.
When you add it up, the same tour could take a splitboarder an extra hour compared to a skier of equivalent ability. Time isn’t everything, but it can be the difference between getting that extra lap in, or getting back to the car before dark.
Like I said, some of my best touring partners are splitboarders, so I don’t mean to bag on it. There’s a reason they still board, and it’s because they can’t give up the feeling of surfing pow. But backcountry snowboarding, whether splitboard or snow shoes is going to create challenges that skiers almost never face.
