That all makes sense to me. After all, the snowmobile companies surviving today make watercrafts in their snowmobile "off seasons". a modern variant on your thoughts.

I always enjoyed seeing those "kits" for sleds that would turn them into summer toys. They would have wheels that would replace the skis (or bolt right onto them), as well as in the back, though the track would still turn.. Of course, these were all for bogie wheeled suspensions which didn't require the lubrication of snow like the sliders did. I think some sleds came with these options available straight from the manufacturer.

There are some good websites with images of sleds of many makes and models. It's always nea tto see and learn about ones I never knew existed. Some have complete fiberglass canopies, housings, etc to enclose the rider.
