last snow storm of season (hopefully ) blew thru here. So took some pics of two empty sleds. The Otter has water skis and the Jet Sled has snow skis. As you can see by pics. The snow ski equipped jet Sled sinks deeper into the snow. Although the Jet Sled is way lighter than the Otter. earlier this season when we had our extremely short ice season in Ohio this year. The water
skis seemed to pull easier.
Without getting into all the scientific crap about surface tension of liquid versus solid. Or the viscosity of any given material. Remember aerodynamics states that bumblebees should not be able to fly.
Anyway thought this was my idea but wife ( damn her ) reminded me at garage sale of old timer seeing my jetsled. Mentioned using waterskis back in the old days for this purpose.
As plainly shown snoskis do sink deeper into snow so not my imagination. Both make the job of towing easier as opposed to bare tub. Course on bare ice everything pulls easy. Since the water skis do present a smaller surface area than just the tub by itself it is far easier to pull when snow enters the equation.
